Abstract
This article develops a novel methodological framework to investigate the exposure of eco-
nomic systems to the risk of physical capital stranding. Combining Input-Output (IO) and
network theory, we define measures to identify both the sectors likely to trigger relevant capital
stranding cascades and those most exposed to capital stranding risk. We show how, in a sample
of ten European countries, mining is among the sectors with the highest external asset strand-
ing multipliers. The sectors most affected by capital stranding triggered by decarbonisation
include electricity and gas; coke and refined petroleum products; basic metals; and transporta-
tion. From these sectors, stranding would frequently cascade down to chemicals; metal products;
motor vehicles water and waste services; wholesale and retail trade; and public administration.
Finally, we provide an estimate for the lower-bound amount of assets at risk of transition-related
stranding, which is in the range of 0.6-8.2% of the overall productive capital stock for our sample
of countries, mainly concentrated in the electricity and gas sector, manufacturing, and mining.
These results confirm the systemic relevance of transition-related risks on European societies.

1 Introduction
A low-carbon transition is now almost unanimously considered as a necessary and likely scenario
(IEA, 2017; IPCC, 2018; UNFCCC, 2016). However, less certainty exists on the socioeconomic
and financial implications of such a large-scale structural change. The decarbonisation process, if
not properly managed, might result in reduced economic prosperity, unemployment and financial
instability. In particular, a significant body of work has been developing to study the extent to
which the low-carbon transition might negatively affect economic and financial wealth by creating
“stranded assets” (Caldecott, 2018). Most of the research conducted so far on the topic has focused
on the stranding of fossil reserves (McGlade and Ekins, 2015; Mercure et al., 2018) or on the knock-
on financial effects of a drop in the market valuation of fossil fuel companies (Battiston et al., 2017;
Carbon Tracker, 2013). The exposure of the financial system to transition risks has also raised the
concerns of international financial regulators, who wish to avoid any risk that might create systemic
disturbance to the global system, still recovering from the global financial crisis (Carney, 2015;
Campiglio et al., 2018).
However, fossil reserves are only part of the picture. In a rapid low-carbon transition, a large
amount of built infrastructure, industrial plants and machinery would have to be abandoned or
entirely reconverted. This applies not only to the stock of extracting infrastructure, pipelines and
other forms of capital linked to fossil fuels, but also to a large amount of industrial plants whose
output requires fossil fuels as material inputs or for process heat (metals, coke, chemicals, steel,
etc). The reduction in production and consequent asset stranding (in the form of idle productive
capacity) would in turn cascade to physical stocks supporting the rest of the economic activity (e.g.
warehousing, transport infrastructure, etc.) following chains of intermediate exchange. While some
studies have explored the stranding of physical productive assets (Pfeiffer et al., 2018; IRENA, 2017),
the topic has not been thoroughly investigated, and never from a systemic perspective.
This article contributes to filling this gap in the literature by providing a novel analysis of the
process through which a low-carbon transition would affect the utilisation of productive capital
stocks at the sectoral level. More specifically, we employ data available for ten European economies
to achieve three main objectives.
First, we use Input-Output (IO) concepts to derive national matrices of “asset stranding mul-
tipliers”, including the entire range of productive sectors. These multipliers capture the monetary
value of physical capital stocks that would become idle (i.e. stranded) in a sector due to a unitary
drop in primary inputs1 utilised by another (or the same) sector, considering both direct and indirect
effects. To offer an example, these matrices are able to provide the monetary value of the capital
stock becoming unutilised in the transportation sector due to a drop in manufacturing, both directly
and through its intermediate effects on, say, wholesale trade. We identify the sectors most likely to
have large stranding effects and the sectors most exposed to the risk of capital asset stranding for
the countries in our sample. While the analysis developed here maintains a systemic perspective,
we highlight how mining - where fossil fuel extraction is included - is among the sectors with the
highest potential to trigger capital asset stranding in the rest of the economy.
Second, we focus our analysis on the mining sector in the attempt to identify the most relevant
channels of asset stranding propagation caused by a low-carbon transition. In order to do so, we treat
the matrix of asset stranding multipliers as an adjacency matrix for a directed weighted network and
show that, while countries exhibit different cascade processes depending on the peculiarities of their
1We define “primary inputs” as the main factors used in production (labour, capital, land, imports, and others).
IO tables report their factor costs (e.g. compensation of employees, consumption of fixed capital or net operating
surplus). See Miller and Blair (2009), Eurostat (2008a) and OECD (2001).

industrial structure, certain regular patterns emerge. The sectors most at direct risk of stranding
include electricity and gas; coke and refined petroleum products; basic metals; and transportation
and storage. The stranding in electricity and gas often cascades in a significant manner down to
public administration and water-related services. The coke and refined petroleum products sector
affects the capital stock of the chemical and land transport sectors the most, with further links to the
rest of transportation sectors (water and air transport, warehousing and postal services). Finally, the
stranding in the basic metals sector has significant impacts on fabricated metal products and motor
vehicles, which in turn cascade down to the trade and repair of motor vehicles. In contrast, the
service sectors appear to be the least at risk in terms of transition-related physical asset stranding.
Finally, we provide a ballpark estimate for the overall amount of productive capital stock at
risk of becoming stranded due to a complete transition away from fossil fuels. Results differ widely
across countries, ranging from less than 1% of capital stock in Belgium and Sweden to more than
8% in Slovakia. In absolute terms, the largest countries in terms of capital stock are also the most
affected ones. In the majority of countries in our sample at least half of the stranding takes place
in the electricity and gas sector. The main exceptions are the United Kingdom, where a large part
of the stranding happens in the mining industry, and Belgium, where manufacturing is the sector
proportionally more at risk. In general, these results confirm that capital stranding driven by a
transition away from fossil fuels could have significant effects on European economic systems.
To the best of our knowledge, our paper is the first to offer a systemic empirical analysis of
the productive capital stocks at risk of stranding due to a low-carbon transition. Previous work on
“committed cumulative emissions” has already shown that the greenhouse gas emissions embodied
in currently existing (and planned) capital infrastructure are incompatible with a 2°C-consistent
decarbonisation process (Davis et al., 2010; Davis and Socolow, 2014; Smith et al., 2019), thus
suggesting the likelihood of premature decommissioning of productive stocks in the event of a low-
carbon transition. Building on these results, Pfeiffer et al. (2018) calculate the amount of capital
stock that would become unutilised in the power generation sector, finding it to be equal to 20% of
total sectoral capacity even in the unlikely event of all currently scheduled projects being cancelled.
IRENA (2017) also provides estimates that suggest a significant capital stranding in several sectors,
including upstream energy, power generation, buildings and industry. However, none of the cited
studies considers the entire range of productive sectors, where capital stranding might take place
through cascade effects, nor disaggregates among industrial sub-sectors.
We complement this literature by providing an alternative methodology to study transition-
related stranding risks based on concepts and methods borrowed from the IO and network analysis
literature. Following Blochl et al. (2011), Acemoglu et al. (2012), Joya and Rougier (2019), and
others, we treat input-output linkages as the edges of a directed weighted network representing the
complex web of economic interconnections among productive sectors. Unlike most of the research in
this field, however, we do not study the effect of demand-driven sectoral shocks on aggregate output
volatility, nor are we interested in determining the “centrality” of sectors. Given the focus of our
analysis, the origin of the shock is by definition located into the mining sector and, we claim, is more
suitably interpretable as a supply, rather than demand, disruption. For this reason, we adopt the
supply-driven IO model (Ghosh, 1958), complementing it with sectoral data on capital stocks.
The Ghosh model can be used to identify the relevance of productive sectors in supporting
downstream economic activity through the calculation of sectoral “forward linkages” (see for instance
Aldasoro and Angeloni, 2015; Antras et al., 2012; Cahen-Fourot et al., 2019) or, in the case of
this paper, their relevance in keeping downstream capital stocks in operation. In contrast, its
plausibility as a theoretical approach to investigate the inter-industry impact of supply changes -
3
especially large ones - has been questioned due to some of its limiting assumptions, such as perfect
elasticity of demand in reacting to changes in supply and perfect substitutability among input factors
(Oosterhaven, 1988; Galbusera and Giannopoulos, 2018). Some of these criticisms can be solved
when treating the framework as a price model (Dietzenbacher, 1997), and are further mitigated
by the features of our specific research questions, which, for instance, do not include the issue of
allocating an excess output supply. Nonetheless, the figures provided in section 4.2 do assume perfect
input substitutability and abstract from dynamic considerations, and should thus be interpreted as
a ballpark estimate of the lower-bound of the capital stock currently at risk of stranding due to the
decarbonisation process.
We also aim to contribute to two additional streams of work. First, our results offer new insights
to the burgeoning literature on the macro-financial implications of a low-carbon transition (Battiston
et al., 2017; Stolbova et al., 2018; Vermeulen et al., 2018). These studies usually investigate how the
value loss of financial assets issued by firms in fossil or fossil-related sectors would affect the portfolio
of financial investors, with potential knock-on effects within the financial network. A more sophisti-
cated assessment of sectoral physical capital stranding would contribute to improving the accuracy
of the real-financial cascade effects. Second, the stress put on the relevance of potential capital stock
underutilisation during a low-carbon transition could contribute to the climate economic modelling
literature, which traditionally focuses on flow variables when evaluating the economic implications
of mitigation scenarios (“GDP losses” or, more recently, “investment needs”), rather than stock vari-
ables (Tavoni et al., 2015; McCollum et al., 2018; Tol, 2009)2. Productive capital assets are often
present in the analysis as the main factor of production (“K”) but, despite a few exceptions (see for
instance Rozenberg et al., 2018; Baldwin et al., 2018), the possibility of their idleness is not usually
contemplated. This methodological approach is justified by the century-long perspective taken by
most of these modelling exercises, a horizon within which shorter-term phenomena (e.g. low capacity
utilisation or a drop in firms’ market valuation) can be netted out by longer-term trends driven by
capital accumulation and technological innovation. However, addressing the complexity of safely
managing the decarbonisation process cannot abstract from these short-term phenomena affecting
both flow and stock variables.
The remainder of the article is as follows. Section 2 introduces the method to compute the
matrices of sectoral asset stranding multipliers. Section 3 presents the results of the analysis for ten
European countries, discussing the sectors most likely to create large stranding and the ones most
exposed to stranding risk. Section 4 focuses on a low-carbon transition, identifies relevant channels
of asset stranding and provides an estimate of the total amount of capital stocks at risk of stranding.
Finally, Section 5 concludes.
2 The asset stranding multiplier matrix
The starting point of the proposed methodology is the inter-industry matrix Z, a square matrix
recording intermediate consumption of industries and thereby showing all the transactions of goods
and services among industrial sectors measured in monetary units (Miller and Blair, 2009).
In an IO table (IOT), the Z matrix is complemented by a set of column vectors representing
final consumption i.e. demand (f) and by a set of row vectors representing value added items (v)
such as compensation of employees, consumption of fixed capital and gross operating surplus. All
sectors appear twice in Z: as producers of goods and services (rows); and as users of intermediate

often incorporated. See Piontek et al. (2018) for a recent example.

inputs (columns). The core principle in IOTs are monetary industry balances, where total supply
xT = iTZ + v must be equal to total use x = Zi + f per industry, where i is a column vector of 1’s
of the same dimension of Z3. In other words, the sum of all flows over a row (total industry output
broken down by type of use, i.e. intermediate use and final consumption) must equal the sum over
the corresponding column (total industry input broken down by “source”, i.e. other industries and
value added items). Two main types of IOTs are usually included in a single-region IO dataset: the
“domestic” IOT reports only goods and services produced domestically; the“total” IOT reports also
imported goods and services, which are again used either as intermediate inputs or as final demand.
Table 1 shows a stylized version of a “total” IO table.
The most common use of IOTs in economic analysis is aimed at estimating the direct and indirect
effects of changes in final demand using the Leontief model, where the matrix is often referred to as
the Leontief “inverse” (Leontief, 1951). However, while both demand and supply patterns will be
crucial in defining the process of decarbonisation, we believe that the demand-driven Leontief model
would not be the most appropriate methodological approach to study the low-carbon transition and
its implications for asset stranding. The shifts in consumption patterns due to climate-related drivers
(e.g. changes in relative taxation, rapid technological innovation, more widespread environmental
awareness) will most likely materialise in shifts of final demand from high- to low-carbon versions
of the same category of goods, rather than a shift between distinct categories. In other words,
consumers will mostly shift their preferences towards energy-efficient durable goods and electricity
produced via low-carbon energy sources, rather than shifting preferences from one category of goods
to another (e.g. from manufactured goods to food products). This is also due to the relatively low
proportion of final demand for fossil fuels, which are instead mainly used by other productive sectors
as intermediate goods. Hence, the main effect of low-carbon transition drivers will concern the way

in which goods and services are produced. In this context, the demand-oriented Leontief model is
not suitable for studying rapid processes of substitution away from fossil-based input factors. We
should instead focus more on the supply side and the production process.
A better methodological approach for our purposes is provided by the Ghosh (1958) supply-
driven IO system (Augustinovics, 1970; Beyers, 1976). Instead of calculating a matrix A of technical
input coefficients as in the Leontief model, the Ghosh model defines a matrix B = x−1Z of output
allocation coefficients, whose elements represent the allocation of the output of a sector to all other
sectors. In other words, each element bij quantifies the share of industry i’s output that is used by
industry j. The Ghosh matrix G is then defined as:
G = (I−B)−1. (1)
For convenience, we transpose G to be able to read the effects of changes in sectoral primary
inputs over the columns (similarly to the Leontief system) of GT , where T denotes the matrix
transposition. Each element gi,j of GT describes the change in output x in sector i that would
result from a unitary change of primary inputs flowing into sector j. In other words, an increase
(decrease) of one monetary unit of primary inputs contributing to production in sector i will increase
(decrease) the output of sector j by an amount equal to gi,j , where gi,j includes both direct and
indirect effects. “Primary inputs” refers to any item appearing on the rows below the inter-industry
matrix. Traditionally, this has been meant to represent compensation of employees (and thus labour
input) but, more generally, it can be used to represent any form of societal effort put in producing
the output of a specific sector, as represented by factor payments.
We then combine the Ghosh matrix with sectoral data of physical capital stocks k. We define
κi = ki/xdi as the capital intensity of sector i, where xd is the domestic output of the sector. By
multiplying the diagonalised form of the vector of capital intensities by the Ghosh matrix, we find
the matrix S of asset stranding multipliers:
S = κGT . (2)
Each element sij of matrix S represents the change in the utilisation of capital in sector i triggered
by a unitary change of primary inputs used by sector j. For our purposes, the elements of S define
the amount of capital stock of a sector i that could become stranded because of a unitary decrease
in the primary inputs used in the production of goods and services of another sector j (e.g. fossil
fuels).
The column sum of matrix S gives a measure of the total amount of stranded physical assets
resulting from a unitary reduction of primary inputs in a sector j. We define this as the total asset
stranding multiplier of a sector:
sTOTj = iTS (3)
where n is the dimension of matrix S. We expect the values of sTOTi to be strongly affected by
sectoral capital intensities, and hence by the amount of internal asset stranding. We thus also
define a measure for the external asset stranding multiplier, to calculate the effect of a unitary
reduction of primary inputs of a sector on the capacity utilisation of capital stocks in all other
sectors:
sEXTj = sTOT
j − sdiagj , (4)
where sdiagj represents the j-th element of the diagonal of S.
Finally, we can interpret the sum of the rows of S as the exposure of a sector to stranding risk
(i.e. the loss in capital utilisation resulting from a unitary loss in primary inputs used in all the rest
6
of the sectors):
sEXPi = Si. (5)
3 Physical capital stranding networks
We apply the methodology described in section 2 to a selection of European countries4. The main
source of data for both IO tables and capital stock data is the Eurostat statistical database. More
specifically, we use symmetric input-output tables at basic prices5 and the cross-classification of
fixed assets by industry and by asset6. In the case of Sweden, we complemented Eurostat data with
retrieving C20-21, H52-53 and M71-72 sectors fixed assets data from Statistics Sweden. Sectors
are classified using the NACE classification system (Eurostat, 2008b). Table 2 lists NACE level 1
categories, while Table A1 in the Appendix offers a more detailed disaggregation. We consider both
physical productive infrastructure (N112N - Other buildings and structure) and machinery (N11MN
- Machinery and equipment and weapons systems)7. This will be referred to as productive capital
hereafter. The geographical representation of our sample is mainly determined by availability of
data, especially for capital stock data. After harmonizing sectoral aggregation between IO tables
and capital stock data, we are able to offer results for ten European countries using 2010 data:
Austria, Belgium, Czech Republic, Germany, Greece, France, Italy, Sweden, Slovakia and the United
Kingdom. In 2010, these countries represented approximately 74% of the European Union Gross
Domestic Product. The disaggregation of data among NACE sectors differs across countries, with
some (e.g. Germany) reporting only NACE level 1 values and others (e.g. Austria) offering a more
disaggregated perspective. For each of them, we use the most detailed disaggregation level available.
Table 3 reports the results for: i) total stranding multipliers; ii) external stranding multipliers;
iii) exposure to stranding risk. We focus on the top 5 sectors for each country. Given the capital
stock composition of the economy and leaving all else equal, the first two sets of multipliers show
the sectors that are likely to create the largest amount of stranded assets in the economic system
following a unitary drop in their primary inputs. The third set of results report instead the sectors
that are likely to be most affected by capital asset stranding from a unitary drop distributed equally
across all sectors8.
Regarding total multipliers, sectors in the E category (Water supply; sewerage; waste manage-
ment and remediation activities) are by far the most prevalent, appearing among the top 5 sectors
for nine out of ten countries, and as the very top sector for six of them. Where further disaggregation
is possible, we observe this to be particularly true for sector E36 (Natural water; water treatment
and supply services). Studying the S matrix, one can notice that sectors often significantly affected
by the stranding originating in E sectors include L (Real estate activities) and O (Public admin-
istration and defence; compulsory social security). In certain countries (e.g. Sweden and Austria)
this is likely to be mainly driven by the high proportion of hydroelectric power in the energy mix9.

an online appendix at: github.com/capital-stranding-cascades/online material.5naio 10 cp1700, total economy, product by product in million e.6nama 10 nfa st, stocks at current replacement costs in million e.7We assume that most dwellings will continue being inhabited even in the event of an abrupt low-carbon transi-
tion, and thus exclude the dwelling category (N111N). We also exclude cultivated biological resources (N115N) and
intellectual property products (N117N).8A large value in this column may represent small contributions from a large number of sectors. In that case, the
risk is mitigated to the extent that changes in primary inputs to those sectors are uncorrelated.9The share of hydropower in the electricity mix was 56.5% for Austria and 44.6% for Sweden in 2010 according to
the World Development Indicators database of the World Bank.

In addition to E sectors, activities included in categories A (Agriculture, forestry and fishing), D
(Electricity, gas, steam and air conditioning), H (Transportation and storage) and O (Public ad-
ministration and defence; compulsory social security) all appear among the top 5 sectors in terms
of total asset stranding multipliers for six of the examined countries. For those countries in which
further disaggregation of category H is possible, we observe a particular relevance of sectors H50
(Water transport) and H52 (Warehousing and support activities for transportation). These results
appear to be strongly driven by the high capital intensity of the sectors, thus highlighting significant
potential internal asset stranding. Significant exception to these patterns are Greece and France,
where sectors N77 (Rental and leasing activities) and B (Mining and quarrying) represent the top
sectors, respectively.
External asset stranding multipliers, which abstract from the internal stranding of a sector and
thus offer a more accurate representation of the stranding effect of a sector on the rest of the
economy, exhibit a significantly different pattern. The relevance of capital-intensive activities is
drastically reduced, although water and waste management activities (E) still exhibit significantly
high stranding effects in Austria and Sweden, and transportation and storage sectors (H) appear
at the top of the ranking of both Czechia and Slovakia. Sectors B (Mining and quarrying), C
(Manufacturing), M (Professional, scientific and technical activities) and N (Administrative and
support service activities) become the most recurrent sectors, appearing among the top 5 sectors for
six, five, seven and nine countries, respectively. For those countries in which further disaggregation
is possible, we notice a particular prevalence of sectors C33 (Repair and installation services of
machinery and equipment), M74 75 (Other professional, scientific and technical activities) and N80-
82 (Security and investigation activities; buildings and landscape; office support). All these sectors
appear high in the ranking of external asset stranding multipliers because they provide significant
amount of inputs to capital-intensive sectors. For instance, both sectors C33 and N80-82 provide
substantial intermediate goods to transportation (H), real estate (L) and public administration (O).
Table 4 offers a closer look at the mining sector, reporting the top 5 sectoral values for the external
stranding multipliers originating in B (excluding B itself, to abstract from internal stranding). Sector

D (Electricity, gas, steam and air conditioning) appears as the sector more at risk of physical asset
stranding in all the countries in our sample except for one. Several manufacturing sectors appear
among the top 5, most notably C19 (Coke and refined petroleum products) and C24 (Basic metals).
Other recurrent sectors are in the A, H and O categories.
Finally, looking at the values of total sectoral exposure to asset stranding, we can identify three
main sectors at risk, repeatedly appearing among the sectors with the highest row sums in S: O
(Public administration and defence; compulsory social security); H (Transportation and storage);
and D (Electricity, gas, steam and air conditioning). Exceptions include the real estate sector (L) in
Austria, manufacturing (C) in Germany, and construction (F) in the United Kingdom. These sectors,
in addition to having high capital intensities, are affected by multiple relevant inward stranding links.
To observe this, we treat S matrix as an adjacency matrix for a directed network (Godsil and Royle,
2013), interpreting productive sectors as the vertices of the network and the si,j elements of S as
the weight of the edges going from vertex j to vertex i. It is possible to represent visually the
network as a chord diagram. Figure 1 shows the outcome of this procedure for Germany, whose low
sectoral granularity contributes in improving the readability of results10. The size of each sectoral
segments is a function of the aggregation of both inward and outward stranding links. While most
sectors exhibit both inward and outward links, there are several (B, F, I, J, M, S) which only have
outward links (i.e. they affect capital stranding in other sectors but are not themselves affected by
any other sector), and one sector (Q) which only has inward links (i.e. it doesn’t create stranding
in any other sector). The figure offers a more detailed and disaggregated picture of the data showed
in Table 3. Sector N has the highest stranding multipliers, with the ones directed towards C, E and
H being particularly strong. The stranding effects triggered by the mining sector (B) focus mainly
on manufacturing (C) and electricity and gas (D). As for sectoral exposure, the sectors most at
risk appear to be manufacturing (with the strongest stranding coming from A and B) and public
administration (with a particularly relevant stranding effect stemming from R).
4 The stranding effects of a low-carbon transition
4.1 Cascades of physical asset stranding
After having shown the stranding potential and the stranding risk exposure of the entire range of
productive sectors, we now shift our attention to sector B (Mining and quarrying). Our aim is to
investigate the relevance of the potential stranding of physical assets due to a transition away from
fossil fuels, and understand how the stranding process originating in the fossil fuel sector might
propagate throughout the economic system. In order to do so, we start by identifying the most
relevant stranding links originating from a unitary loss of primary inputs supporting the production
of B (i.e. the largest values appearing on the B column of matrix S). We retain only the top q
percentile of the values, and position the affected sectors on the first layer of our cascade network.
We repeat the procedure for the sectors in the first layer, identifying the sectors within the top q
percentile of stranding links originating in the layer. The weight of the resulting network edges are
re-weighted to take into account that the loss in primary inputs in these sectors will be lower than
one and a function of the strength of the upper edges. In other words, the stranding links tend
to be stronger the closer they are to the shock origin, and get gradually weaker as they cascade
downwards. We then repeat the same procedure for each layer, excluding the sectors that had
10To further ease readability, we first eliminate less relevant network connections computing the “minimal fully-
connected network” of S as in Campiglio et al. (2017).

Figure 1: Chord diagram of S minimal fully-connected network for Germany (2010)
already appeared in upper layers, until no new sectors appear. The results of this procedure for a
selection of countries11 are shown in the pyramid-like networks of Figure 2, for q = 0.05. The width
of the edges as represented in Figure 2 are proportional to their weight. The numerical weight of
the top 10 edges is shown for reference.
The sectors in the first layer of the network overlap with the ones reported in Table 4. The
strongest stranding link is the one flowing to the D sector (Electricity, gas, steam and air condition-
ing) for all countries with the only exception of Belgium. Manufacturing activities, especially coke
and refined petroleum products (C19) and basic metals (C24), as well as transportation and storage
(H), also frequently appear among the sector most strongly affected by the immediate stranding
caused by B. From the electricity and gas sector (D), the stranding cascade often continues affecting
public administration (O) and water services (E36). Given the strength of the original stranding
from B to D, these links are often the most relevant after the ones affecting sectors in the first layer,
and are justified by both the high capital intensity of the sectors and their large consumption of
D products (e.g. water pumping and purification are energy intensive). From the coke and refined
petroleum products sector (C19), the most common cascades proceed through the chemical sector
(C20) and the land transport and pipelines sector (H49). The stranding in the basic metals sector
(C24) often propagates through to the fabricated metal products (C25) and the motor vehicles sector
(C29), with the latter frequently further affecting trade and repair of motor vehicles (G45). Finally,
when the disaggregation among H subsectors is available, we observe a relevant stranding clustering
11The choice of the four countries represented in Figure 2 was mainly determined by the granularity of national
data and the richness of the resulting networks. The cascades for the rest of the countries in our sample can be found
in the appendix.

Figure 2: Cascades of productive capital stranding for selected countries
among them, and especially between land transport and pipelines (H49) and warehousing (H52).
In addition to the sectors mentioned above, several other sectors frequently appear in the cas-
cade networks. For instance, public administration (O) often appears on the second layer of the
network affected by multiple stranding links (originating from electricity and gas, transport sectors,
and others). The sectors in the E category also often appear, sometimes with E36 (water services)
affecting E37-39 (sewerage and waste services). The latter in turn sometimes appears to have rele-
vant stranding links towards basic metals (C24). Of the primary sectors, only agriculture (A01) is
12
present in the cascade networks (presumably due to high fossil-fuel inputs in modern agricultural
systems), while forestry (A02) and fishing (A03) never appear. Service sectors such as information
and communication (J), finance and insurance (K), professional services (M), administrative services
(N), Human health and social work services (Q) and arts and recreation services (R) also tend not
to be present in the networks, or only to appear at lower layers, suggesting that the decarbonisation
process might not be particularly detrimental for them in terms of capital asset stranding. Accomo-
dation and food services (I), on the other hand, is often present and usually affected by stranding
cascading from agriculture (A01).
Studying the structure of the networks in conjunction with the weights of its edges, we can identify
particularly relevant cascades. Both in Austria and Czechia it is possible to observe a deep stranding
cascades passing through sewerage and waste (E37-39) and basic metals (C24), and then affecting a
significant number of manufacturing sectors (fabricated metal products, machinery and equipment,
motor vehicles, and others) as well as trade of motor vehicles (G45). Sweden exhibits several fairly
long stranding cascades, with the most prominent one passing through coke and refined petroleum
products (C19), land transport and pipelines (H49), warehousing and postal services (H52-53) and,
finally, water transport (H50). The cascade network of the United Kingdom is peculiar, in that it
has two particularly deep cascades originating in wholesale trade (G46), with the first one involving
several manufacturing sectors and agriculture, and the second one mainly involving service sectors
(accommodation and food, residential care and social work, sports, arts and others).
4.2 The capital stock at risk of stranding in a low-carbon transition
The aim of this section is to provide an estimate of the overall productive capital stock at risk of
becoming stranded from a switch away from fossil fuels. In order to do so, we must distinguish fossil
fuels from metals and minerals in the use of B sector products by each sector in each country12.
However, the Eurostat database does not provide the required granularity. To overcome this issue,
we use the data provided by Exiobase (Wood et al., 2015), a multi-regional IO database covering 200
types of products13, to calculate the proportion of fossil fuels within the overall use of B products
by the sectors of a national economic system. This proportion tends to be close to 100% in the
electricity (D) and manufacturing (C) sectors of many countries, while it is usually closer to zero
for sectors such as construction (F) and wholesale and retail trade (G). Calling fi the fossil fuel
proportion of sector B product use by sector i, we define the amount of capital at risk of being
stranded due to the transition away from fossil fuels as
Strandi = fisi,BZB,ji
GB,B, (6)
where si,B is the element of matrix S representing the stranding effect on sector i of a unitary drop
in primary inputs used in sector B, ZB,ji is the sum of the elements of row B in the inter-industry
matrix Z representing the total use of products of sector B in the economic system, and GB,B is
the B element of the diagonal in matrix G representing the loss in production in B due to a unitary
drop of primary inputs in the same sector. Division by GB,B transforms the projected loss in output
of sector B into the equivalent loss of primary inputs required to produce it, making it compatible
with the units used by S.
12Sector B includes several distinct activities: Mining of coal and lignite (B05); Extraction of crude petroleum
and natural gas (B06); Mining of metal ores (B07); Other mining and quarrying (B08); and Mining support service
activities (B09). While only some of them concern fossil fuels (B06, B07 and, partially, B09), available Eurostat data
for the sector is usually presented in an aggregated manner at the NACE level 1 category.13The database is available at www.exiobase.eu.

Table 5: Productive capital stock at risk of stranding (million e at current prices in 2010 and share
of total/sectoral capital stocks)
This procedure must be amended in the case of the B sector itself, where the stranding of the
capital stock triggered by a transition away from fossil fuels will originate from the phasing-out of
production (e.g. oil platforms remaining inactive) rather than a lack of input factors as in the case
of all other sectors (e.g. electricity plants interrupting production because of missing fuels). Using
Exiobase, we calculate the ratio of fossil fuels production on the overall production of sector B and
assume that the same proportion of capital stock of sector B is to be considered at risk of stranding.
The stranding impact on the remainder of the capital stock in B, used to extract metals and other
materials, is calculated using the same methodological approach as the rest of the sectors14.
Table 5 reports the results of this procedure. The overall amount of capital stock at risk of
stranding due to a transition away from fossil fuels is shown in the first column (values in million e;
share of total capital in brackets). The largest absolute exposure is in the United Kingdom, where
around e84 billion worth of capital stock (3.6% of the value of the total capital stock) may become
idle if fossil fuels were not used in production anymore. The other large economies in the sample
(Italy, Germany, France) follow, with approximately e59, e40 and e36 billion of capital at risk.
The least exposed countries in proportional (and absolute) levels appear to be Belgium, Sweden and
Austria (0.6%, 0.8% and 0.8% of total capital at risk, respectively), while Slovakia is by far the most
exposed economy, with around 8.2% of its productive capital stock at risk. The remainder of the
columns report the stranding values for the three sectors that tend to exhibit the highest sectoral
stranding across countries: B (Mining and quarrying), C (Manufacturing) and D (Electricity, gas,
steam and air conditioning).
The stranding of physical capital in sector B strongly varies across countries. In absolute terms,
the United Kingdom is by far the most exposed, with around e46 billion (69.3% of total capital
in sector B) at risk of stranding in the form of built infrastructure for the extraction of oil and
gas, especially in the North Sea. No other country in our sample gets close to these values. In
contrast, mining sectors in countries such as Austria and Sweden, are only minimally exposed,
as they are relatively small and mainly oriented towards the production of metals and minerals.
In proportional terms, the United Kingdom, Czechia and Greece appear to be the most exposed
countries. Computations based on World Development Indicators natural resources rents and current
prices GDP data for 2010 show that oil amounts for 84% of the total natural resources rents (that
14Lacking a specific value in the G matrix capturing the output effect of a unitary loss in primary inputs for fossil

14
include coal, forest, mineral, natural gas and oil) of the UK while coal amounts for respectively 78%
and 45.7% of Czechia and Greece total natural resources rents. This indicates that the mining sector
of those countries is dominated by fossil fuels15, which explains the high stranding values of the B
sector capital stock.
The manufacturing sectors in our ten countries are all quite significantly exposed, in a range
that has France as the lower bound (2.1% of total C capital at risk of stranding) and Slovakia and
Greece as the upper bound (7.7% and 8.1%, respectively). Such a high exposure may be explained
by the share of the coke and refined petroleum products sector (C19) in the whole manufacturing
productive capital stock: 11% for Greece and 8.1% for Slovakia, with a sample average of 4.3% 16.
Conversely, the French C19 sector only amounts to 1.9% of its whole manufacturing sector capital
stock. For Slovakia, the motor vehicles, trailers and semi-trailers and other transport equipment
sector (C29 C30) also amounts to 18.1% of the capital stock, with a sample average of 11.2%.
Moreover, it is important to note that the figures in table 5 take into account the indirect effects
of a complete decarbonization, that is the effects through the non mining sectors supplying the
manufacturing sectors. Therefore, these percentages capture the reliance of the manufacturing
sectors both on raw fossil fuels and on fossil fuels dependent sectors, i.e. transportation.
Turning to electricity and gas, the capital at risk of stranding in this sector is the largest sectoral
value in absolute terms for all the countries in our sample with the exception of the United Kingdom.
Italy is exposed by around e31 billion worth of capital, followed by the UK (e28 billion), France
and Germany (both around e21 billion). In proportional terms, the most exposed countries are
the UK and Slovakia, followed by Czechia and France. Part of the explanation lie in the electricity
production capacities. Generation capacity based on fossil fuels amounts to 77.5%, 40.6%, 56.8%
and 20.5% of the total electricity production capacities in, respectively, the UK, Slovakia, Czechia
and France. The electricity generation origins vary considerably between these countries: the UK
and Czechia produce respectively 76.4% and 60.1% of their electricity from oil, gas and coal sources
but this figure is only 25.1% for Slovakia and 10% for France. This level of exposure of the Slovak
and French D sectors to decarbonization is consistent with their electricity generation, which is,
respectively, 53.1% and 76% from nuclear power and 21.6% and 14% from renewables, according to
World Development Indicators data.
Due to data availability and limitations of IO data, the estimates provided should be taken as
rough ballpark figures. First, it is likely that the decarbonisation process would entail a gradual
phase-out of fossil fuels utilisation as production inputs rather than a sudden and complete disap-
pearance (Kemp-Benedict, 2018). In this sense, the figures provided should be interpreted as the
upper bound of capital stocks that would potentially become idle due to a low-carbon transition. In
a dynamic perspective, a forward-looking technological shift to low-carbon inputs, combined with
the gradual depreciation of current fossil-intensive capital stocks, would lead to lower stranding
impacts. Second, the analysis attributes shares of sectoral capital stranding in proportion of the
relative use of fossil fuel among all the production input factors of a sector, thus implicitly assum-
ing complete substitutability among input factors and ignoring complementarity effects. In reality,
however, the relative proportion of capital asset stranding due to, say, diesel is likely to be much
larger than its monetary share among input factors, for the simple reason that without diesel a
significant proportion of machinery cannot operate at all. In this sense, hence, the figures provided
represent the lower bound of capital asset stranding due to the loss of essential production factors.
15This needs to be nuanced for Greece: non-fossil fuels mineral resources amounts for 48.4% of the country total
natural resources rents.16We exclude Germany from this computation because disaggregated data is not available for C sectors.
15
Third, using static IO data, it is not possible to fully capture the macroeconomic feedback triggered
by a low-carbon transition, which would also affect employment and aggregate demand, with more
complex implications for the overall capital stranding.
5 Conclusions
The transition to a decarbonised economic system will involve a large-scale reallocation of material
and economic resources. While an expanding literature has been investigating the economic and
financial repercussions of leaving fossil reserves in the ground and the consequent loss in market
capitalisation of fossil companies, less attention has been devoted to the understanding of the poten-
tial stranding of productive physical capital stocks, and how this would cascade within the network
of economic interdependencies. This article contributes to this effort by providing an original mea-
sure to quantify the monetary value of productive capital stock of a sector that is at risk of being
unutilised because of a reduction of primary inputs flowing into another sector.
Analysing the data available for ten European countries, we have shown the sectors with the
highest “asset stranding multipliers” to be linked to water and waste management (E); real estate
(L); and public administration (O). This result is mainly driven by the high capital intensity of the
sectors and the consequent significance of sectoral internal capital stranding. When abstracting from
internal effects with the aim of identifying the sectors that are likely to have the strongest stranding
impacts on the rest of the economic system, we have found the mining and quarrying sector (B) to
be particularly relevant, together with sectors linked to manufacturing (C); professional, scientific
and technical activities (M); and administrative and support service activities (N). These sectors are
key in providing essential inputs to other sectors with high capital intensity. Finally, we have shown
how the sectors most exposed to the risk of capital asset stranding include public administration
(O); transportation and storage (H); and electricity, gas, steam and air conditioning (D).
When focusing more specifically on the mining and quarrying sector in the attempt of studying
the stranding effects of a low-carbon transition, we have shown how moving away from fossil fuel
would have a particularly strong stranding effect on sectors linked to electricity, gas, steam and air
conditioning (D); coke and refined petroleum products (C19); and basic metals (C24). We have
identified regular patterns in cascade structures, such as the links from electricity and gas (D) to
water services (E36) and public administration (O); from waste services (E37-39) to basic metals
(C24) and then to fabricated metal products (C25) and motor vehicles sector (C29); from the coke
and refined petroleum products sector (C19) to the chemical sector (C20) and the land transport
and pipelines sector (H49). Other sectors usually present in the stranding cascade networks include:
agriculture (A01), wholesale and retail trade (G), transportation and storage (H), accommodation
and food services (I) and public administration (O).
Finally, we have provided a ballpark estimate of the overall and sectoral productive capital at risk
of stranding due to a transition away from fossil fuels. The figure is in the range of 0.6-8.2% of the
overall productive capital stock for our sample of countries. In absolute terms, the United Kingdom
has the largest stock of capital at risk (around e85 billion), a result mainly driven by the stranding
of its fossil extraction infrastructure. The UK is followed by Italy, Germany and France, where more
than half of the capital stranding takes place in the electricity and gas sector. In proportional terms,
Slovakia is the most affected country in our sample, with 8.2% of its productive capital stock at
risk of stranding. In contrast, the least affected countries are Belgium, Sweden and Austria, with
0.6-0.8% of overall productive capital at risk. Looking at specific sectors, the stranding in mining
and quarrying varies widely across countries, depending on the size of the sector and the relative
16
share of fossil fuels over metals and minerals. While the UK mining would suffer a loss of almost e46
billion of its capital stock, only e1 million is at risk of stranding in Belgium. The manufacturing
sector is significantly affected in all countries in the sample (never less than 2% of its capital stock
is at risk). Greece is the country with most manufacturing capital at risk in proportional terms
(8.1%), while Italy would lose the largest amount in absolute terms (almost e20 billion). In the
electricity and gas sector, the relevance of capital stranding strongly depends on the energy mix
used to produce electricity, going from 1-3% of sectoral capital in Belgium and Sweden to as high
as 35% in Slovakia and United Kingdom.
The results of our analysis suggest that the drop in capital utilisation triggered by an abrupt
and unplanned transition might be substantial and systemic. While our methodological framework
is not able to provide insights regarding the transition dynamics, the large proportion of productive
assets directly or indirectly dependent on fossil inputs, together with the planned capital expansion
in coming years, indicate that cascading physical capital stranding is a likely scenario to consider.
This offers valuable insights for two main areas of work. First, current research studying the impli-
cations of climate mitigation trajectories through numerical simulations, usually predicated on the
assumption of full capital utilisation, might be underestimating the economic effects of a low-carbon
transition. Second, the burgeoning literature on the macro-financial repercussions of the decarbon-
isation process might improve its analytical power by considering the effects of financial stranded
assets in a wider range of productive sectors than just fossil extraction and power generation. En-
hancing these strands of research with the inclusion of capital utilisation considerations will support
policy-makers in the management of a rapid and smooth transition to a low-carbon economic system.
