Food Climate Research Network
This presentation• Climate change: an overview• Food & its contribution to climate changing
emissions by life cycle & food type• Specific issues: transport, refrigeration, waste,
health• Climate change & its impact on food supply chains• How might we reduce food chain emissions?• What’s going on? Government & industry• Observations & conclusions• About the Food Climate Research Network
1. Climate change: an overview
The facts
• Latest (2007) IPCC report:• ‘Warming of the climate system is
unequivocal…’• Most of the observed increase in globally
averaged temperatures since the mid-20th century is very likely [over 90% certainty] due to the observed increase in anthropogenic greenhouse gas concentrations
Climate change…
• Temperature increase of 0.74ºC in last 100 years
• 11 of last 12 years have been the warmest on record
• Warming of oceans• Faster than average warming in Arctic
What is more…
• Under BAU temperatures to rise by about 3°C by 2100 (range: 2 to 4.5°C ).
• 2°C rise = ‘dangerous climate change’• We’re already ‘committed’ to 1°C rise even if we
stop producing any more GHGs right now.• We need to achieve 80% not 60% cuts by 2050• UK not meeting our CO2 reduction targets
• Will EU meet its 2012 Kyoto target (8% cut)?
Defining terms
GHGs = greenhouse gas emissions
CO2 the main GHG but…
…others also important especially for food• Methane 213 x greater global warming potential than CO2
• Nitrous oxide 296 x greater global warming potential than CO2
• Refrigerant gases thousands of times greater than CO2
2. Overall food related GHG emissions
Need to consider emissions at all stages
Need to consider emissions at all stages in the food chain:• Agriculture• Manufacturing • Refrigeration• Transport• Packaging • Retail• Home • Waste
They all affect one another

Overall food-related contribution to GHG emissions
• EU EIPRO report: 31% all EU consumption related GHGs
• FCRN UK estimates: around 19% (probably an underestimate) - Defra estimates similar
• World agriculture contribution – 17 - 32% total global emissions
• Huge uncertainty / variability between countries / differences in what’s included and what’s not
UK GHG emissions – how does food contribute?
Agriculture7.4%
Fertiliser manufacture1.0% Food manufacturing
2.2%
Packaging (incomplete data)0.9%
Transport incl overseas2.5%
Home food related2.1%
Retail 0.9%
Catering1.5%
Waste disposal0.3%
Non food81.3%
FCRN work in progress 2007
The GHG ‘hotspots’ vary by food
1. Agriculture Meat & dairy; glasshouse veg
2. Manufacture Bread baking
3. Storage Frozen peas or potatoes
4. Transport Anything airfreighted eg. berries
5. Cooking Baked potato, pasta, tea, coffee
6. Packaging Small bottle of beer
7. Waste Fruit & veg
And there are real difficulties drawing meaning from your measurements
For example:• Relative contribution: Eg. Banana transport emissions
greater than strawberries since we eat more of them but flown-in strawberries are more GHG intensive by volume. Policy implications?
• Specific behaviour: farmer, consumer – huge variations How do you address this?
• What’s the functional unit? Emissions per KG? vit C? pleasure? What do you want to achieve?
• System boundaries: Farm machinery? How employee travelled to work? When does food end and everything else begin?
• The existing infrastructure eg. Refrigeration: If the fridge is on whether the peas are in there or not can we really attribute refrigeration emissions to those peas? And what does it mean for the consumer?
Impacts by food type: FCRN work so far
• Meat and dairy – about 8%
• Fruit and veg - about 2.5%
• Alcoholic drinks – about 1.5%
• This is of the UK’s TOTAL GHG emissions• Similar to this Dutch study…

Food impacts by type: Fruit & vegetables
• GHG contributions approx 2.5% total• Trends: increasing consumption of GHG
intensive produce:– Air freighted– Unseasonal protected – Pre-prepared– Fragile / spoilable
Key impact areas
• Transport– 1.5% f&v air freighted, accounting for 40 – 50% total
f&v transport emissions– Air freight growing rapidly
• Refrigeration– from post harvest home– Trade offs AND synergies with transport
• Waste – Approx 25% fruit and veg wasted – most at domestic
stage– Supply chain demands make waste inevitable
Less GHG intensive produce
• Seasonal and field grown: no heating; fewer ‘tradeoffs’
• Robust (less need for rapid transport, less prone to waste, less temp critical?)
Food impacts by type: Alcoholic drinks
• Contributes around 1.5% UK total
• Not much difference between types
• Hotspots: hospitality sector, transport, packaging
• Lack of data

Trends:
• More wine: relative importance of transport to grow?
• More chilled: cold lagers, cider over ice, chilled wine, spirit mixers
• More in-home: more single serve packages
• Hospitality sector??• More drinking
Scope for reduction?
• Brewing / distilling: progress being made• Packaging: lightweighting (but little recycling
from pubs etc.)• Hospitality sector: no policy focus here yet (but
this is changing – more later)• Consumption: adherence to Dept of Health recs
would lead to 18% reduction in consumption. BUT– Rebound effect– International trade
Food impacts by type: Meat & dairy
• Global – 18% global emissions (FAO 2006)
• EU – 15% EU emissions or 50% of all food impacts (EIPRO 2006)
• Dutch study: 50% of all food impacts• UK (from FCRN study):
– 6.6% production related GHG emissions (NETCEN & other)
– 8% consumption emissions (Cranfield plus volumes based on MLC & Defra)

But per capita developing world demand still lower than developed world (IFPRI 2001)
Poultry takes biggest share of growth
But
• We have to eat – there’ll always be an impact
• Livestock production yields food and non food benefits – they ‘save’ having to produce them by other means
• Some livestock rearing utilises unproductive land & by-products
• Would non-animal substitutes be any better for GHG emissions?
To understand why the impacts arise and how/whether they can be reduced you need to look at
• The inputs to the production system and GHG implications
• The outputs from the system and GHG implications

Different systems have different inputs & outputs
Livestock system inputs
• Cereals: How much? Alternative uses (food, biofuel)?
• Oilseeds: Second order impacts? Relationship between cake and oil?
• Grazing land: Inputs to? Alternative uses? Benefits of?
• By-products: Alternative uses? • Land: What’s the best way of using
the land for most output at least GHG cost?
• Energy: on farm and indirect
• What are the second order impacts eg. Lost carbon sequestration from land clearance?
• What is the opportunity cost – could these inputs be used in other ways?
Livestock system outputs
• Nutrition: protein, calcium, iron, B12, fat…• Leather & wool• Rendered products: glues, soaps, pet
food…• Manure: nutrients and soil quality• Soil carbon sequestration• Landscape aesthetics & biodiversity
Questions
• What benefits do we gain from livestock production?
• Are these benefits accurately accounted for in life cycle analysis?
• How much do we need these products?– (who defines need?)
• To what extent can we obtain these goods / services by non livestock means and what would the GHG implications be?
General conclusions on meat, dairy and nutrition
• Good source of calcium, iron & Vit B12• Not so important for protein• Provides fat in excess• Livestock products not essential• But useful in small quantities esp. for
vulnerable groups• Different issues for rich in developed world
and extremely poor in developing world
Non food benefits
• Leather: useful byproducts but not ‘needed’ at current levels (but developing world industries)– Comes with own environmental downsides
• Wool: v. small textile player• Rendered products: are we making the
most efficient use of the carcass?
Manure
• Costs & benefits– Avoids need for mineral fertilisers (although
harder to optimise input levels)
– Contributes to soil quality / carbon sequestering properties of soil
– Leads to methane and nitrous oxide emissions
Soil carbon sequestration, biodiversity & aesthetics
(grazing land) • Pasture land important for carbon
sequestration & biodiversity• But 20% land degraded by overgrazing
worldwide (73% in dry areas)• Hence carbon losses and decline in
biodiversity
Mitigation: relative importance of different gases - GWP
Source: Williams AG (2007) per comm. Based on Williams, A.G., Audsley, E. and Sandars, D.L. (2006) Determining the environmental burdens and resource use in the production of agricultural and horticultural commodities. Main Report. Defra Research Project IS0205.
Mitigation options
1. Husbandry (feed, breed etc)
2. Changing management (organic vs non
organic, intensive vs extensive)
3. Managing outputs (manure)
4. Changing numbers
In the context of
• Framing issues: Animal welfare, biodiversity, long term soil quality and soil carbon storage, rural economy
• Managing trade offs: With other social / environmental concerns & pollution swapping
• Land use: Need to consider the opportunity cost of using land for one purpose over another
GHGS: Foods with major impacts
• Meat and dairy– 8% + UK estimate– 13.5% total EU GHG emissions (half of all food
emissions): could we get our protein / iron / calcium / shoes /warm jumpers / glues in other ways?
– FAO estimates livestock =18% global GHG emissions• Certain kinds of fruit and vegetables
– Veg diets not always better• ‘Unnecessary’ foods and drinks – alcohol,
beverages, confectionary– Whose needs? Who defines them? (more later)
3. Specific issues: Transport, refrigeration,
waste, health
Transport: What about food miles?• 2.5 – 3.5% of UK GHG emissions (incl imports)• Is nearer better? It depends….• There are trade-offs to consider
– Eg. agricultural production, manufacturing efficiency, energy mix, cold storage, waste
• On the other hand…relationship between transport distance & refrigeration, & waste
• Structural impacts on economy and infrastructure investment
• Conflicting demands on land eg. biofuels. What should we use our land for?
• ‘Answer’ now might be different to ‘answer’ in 5 – 10 years time
What about air freight?
• The most GHG intensive form of transport
• Less than 1% all food carried by air but = 11% total food transport CO2 (including car trips)
• 1.5% fruit and veg carried by air but accounts for 40% total f&v transport CO2
• Kenyan green beans 20-26 times more GHG intensive than seasonal UK beans
Air freight continued….
• Absolute impacts small but in relative terms growing – and it subsidises passenger air travel
• The greater the volume, the cheaper it is to fly food
• Food is the fastest growing air freighted commodity
• Might climate change increase use of air freight (variability of supply leads to more use of emergency ‘top ups’)?
Is air always the worst option?
Sometimes other options can be more GHG intensive (eg. hothouse flowers in Feb from Holland compared with those from Kenya)
BUT
This doesn’t meant that air freight is ‘okay’It just means that both have very high impacts!
However…air freight and developing countries
Contribution of SSA countries to total non-EU fruit and veg air freighted imports:
• Kenya 22%• S Africa 6%• Ghana 6%• Zimbabwe 3.6%Of top 20 air freight importers by volume, almost all less developed countries1-1.5 mill people dependent on export horticulture • in SSA (up to 120,000 directly employed) • Lives depend upon it – some excellent projects• Joined up Govt policy implication?
Refrigeration life cycle stage

Contribution to UK GHG (total 179 MTCe)
Manufacturing 0.28 0.18%
Food retail & catering
1.46 0.97%
Domestic 1.9 1.24%UK total 3.64 2.39%
Embedded impacts from imports & emissions from mobile refrigeration not included. IF THEY WERE....
Food refrigeration & GHGs
Then overall refrigeration GHGs 3-3.5% of UK total
• Total food related GHGs around 19-20%
• Food refrigeration = 17-18% all food GHGs
Reducing impacts:How far will technology get us?
• Savings between 20-50% possible
• Novel technologies eg. trigeneration
• Institutional inertia & short term costing
• Policies in place / being developed
• Masses of advice
But we now live in a refrigeration dependent society: Why?
• Changes in foods & drinks we buy
• Changes in how we live our lives– Economic changes– Weekly shopping– Women – Lifestyles – Housing design/ temperatures
• Infrastructure development stimulates cold food manufacturing which stimulates infrastructure investment – and reinforces behavioural norms
Future refrigeration trends?
Some projections refrig. emissions set to decline. But:
• A warming climate? More dependency• New product innovation?
– product/technology/behaviour interface• Can’t look at refrigeration emissions alone:
– Nexus of transport, packaging, retail and IT infrastructure within which refrigeration technology is situated.
In short
• Refrigeration as marker of unsustainable energy use? – Nodal point of energy intensive
practices/behaviours
• Policies need to tackle not just
refrigeration energy use but refrigeration dependency
A less refrigeration dependent food chain
Foods• Less meat and dairy• Fewer ‘fragile’ foods• More seasonal robust produce
More frequent shopping / cooking patterns
Optimum fridge size / level of infrastructure?
Food safety / waste - issues more nuanced than at first appears.
Waste: why is it a problem for food GHGs?
• Decomposing food generates methane (small problem)
• Wasted food represents a waste of all the emissions generated during the course of growing, processing, storing, transporting, retailing and cooking the food. (BIG PROBLEM)
• Around1/3 food we eat is thrown away, most of it edible.
The most wasted foods• Top 5 waste categories: fruit and veg, meat and
fish, bakery, dairy, rice and pasta• High waste foods = mostly also GHG intensive• Most waste occurs at household stage – once food
has ‘embedded’ upstream GHG emissions
• BUT: • If we waste less will we buy less? Will farmers grow
less? Will supermarkets sell less food & but more GHG intensive? Or energy using non food products? Will we export more / import less? What are the policy implications? What action is needed?
What about organic?
• Many benefits to organic:– Long term soil quality– Biodiversity
• But it’s not always less GHG intensive– Eg. Poultry
• ALTHOUGH it sometimes is!• So how do you act consistently?
Is healthy food less GHG intensive?
It depends…
Potatoes
Dried peas
Carrots
Two balanced meals…A ninefold GHG difference
Rice
Tomatoes
Pork
Production of meal on the left is nine times less GHG intensive than the one on the right

4. Impact of climate change on the food system
Impacts on agriculture
Huge uncertainty... Impacts depend on Interplay between:
• Gradual temperature increase• CO2 effect• Wildcards (extreme drought, flooding)• Water• Economics, demographics, infrastructure
Impacts continued...
• May be positive in N. Countries up to 2050 - then negative
• Poor countries – negative and then more negative
• Changes in crop suitability• Crop and livestock diseases• Water
• Poor will suffer most
Source: IPCC 2004 Wkg Gp II Ch5
The picture by 2050
Climate change – knock on effects
• If current sources no longer viable – need to source from elsewhere (further?)
• Increasing reliance on emergency top ups (by air)?
• Weather related spoilage / waste
Major commodity crops - impacts
– Wheat: North – South divide– Rice: water shortages– Cocoa: W. Africa – threat from drought
– Coffee: more vulnerable– Wine grapes: water? Quality? – Cane sugar: water
• Increased developing world dependence on imports from developed world
Post harvest impacts
Food sourcing, processing and distribution• Disruptions to transport & stationary infrastructure• Unpredictability can lead to crop spoilage & waste• Changes in sourcing decisions? • More imports to developing worldConsumption• Changes in consumer demand?• Consequences for food industry & household
energy use?• Food safety problems?
The CC context
• Physical effects of CC need to be seen in social, economic, political, demographic and infrastructural context – feedback interactions
• Climate change exacerbates existing vulnerabilities of poor in developing world
• The more rapid the climate change the harder it will be to adapt
• Poor farmers less likely to be able to adapt – infrastructural, political, economic barriers
What might the impacts be for food supply?
• Current sources no longer viable?• More variability of supply?• Challenges for transport / distribution
infrastructure• The ‘right’ sourcing answer from a GHG
perspective depends on which part of the supply chain cleans up its act / adapts first
• Impact of legislation may be more important in the short term
5. Reducing food’s GHG contribution
How far will technology get us?
• Agriculture: plant breeding; better nutrient use; alternative fuel sources for greenhouses
• Manufacturing: CHP / trigeneration / polygeneration / life cycle costing
• Refrigeration: 20-50% efficiency savings possible; novel technologies including non HFC refrigeration, trigeneration (increases efficiency from 38% to 76%).
• Packaging: lightweighting, alternative materials, ambient storage packaging
More technological options
• Transport: modal shift, efficient supply chains; cleaner fuels (in future years)
• Retailing: massive scope for improvements in lighting and refrigeration; renewables
• Domestic: energy efficient appliances, visible energy metering
• Lots of little impacts/solutions rather than one big one
But
• Will this get us to an 80% cut by 2050?
• Technological improvements don’t address the root problems of the way we consume
• And technology shapes behaviour, fostering new (energy dependent) norms
• Two examples…
Eg.1: Ready meal vs home cooking
• Is the energy efficient ready meal the answer? * No trimmings or scraps: less waste* Production stage scraps can be used for animal feed* No packaging for individual ingredients* More efficient industrial ovens* Only transport what is eaten: less transport* Recent LCA showed little difference between home and ready-meal
But: complex multi-ingredient, elaborately prepared food
reliant on long supply chains and refrigeration becomes the
norm – triggering further innovations…problem exacerbated?
Eg. 2: Food waste: how to reduce?
• Wasted food = wasted CO2 + CH4• One third food bought is not eaten• The technology approach? Improve packaging,
portion size (no leftovers), extend food life span to match our lifestyles? Keep food properly refrigerated. Shrink-wrapped cucumber last longer than unpackaged cucumber
• The behaviour approach? Plan your meals, shop little and often, eat food soon after you’ve bought it, use your leftovers, compost scraps, shared living? Eat that cucumber sooner rather than later!
What might a less GHG intensive way of eating look like?
• Changing the balance of what we eat – Less meat & dairy - lower down on food chain
• Seasonal field grown foods (less storage, heating & transport)– UK seasonal when possible– Elsewhere seasonal when not
• Not eating certain foods– Avoiding hothoused/air freighted produce (but
developing world?)• Reducing dependence on cold chain
– Robust foods (including less processed)– Frequent non car based shopping / frequent turnover
of food
Less GHG intensive eating
• But wasting less– Eat what we buy, soon after we’ve bought it– Accepting variability of quality and supply
• Efficient cooking– Cook for more people and for several days– Less use of oven
• Redefining quality– Accepting different notions of quality– Accepting more variability

Food and its meanings
Influenced by wider forces• Price / affordability• Availability• Time – work / ‘stressed leisure’ syndrome• Culture, social & family expectations, norms, aspirations• Knowledge, information, fashions & beliefs (education,
media, marketing)• Demographic changes: ageing population, single person
society, wealth • Technological changes • Season • Tastes • Habits
What might this mean for the food industry?
Consistency, choice, ubiquity, availability, variety…
Versus
Less choice? More variability of quality? Non availability? A move away from cheap meat? From chilled foods….
You cannot wait for consumers to change their behaviour
• They don’t know enough• They don’t care enough• Behaviour ‘lock-in’
• They won’t unless they have to... Govt and industry must take the lead – change the context of consumption
6. The policy context – global and UK
The global context
• Rising population – 9 billion by 2050• Increasing food / oil prices• Dash for biofuels• Nutrition transition• Land pressures• (Climate change legislation...)
A few framing policies/initiatives
• Kyoto Protocol• Bali 2007 agreement on deforestation• EU Emissions Trading Scheme• European Commission Energy Policy
– 20% GHG cut by 2020 (should be 30%+)– Biofuels 10% transport fuels by 2020
(criticisms)• Biofuels support – EU, US
The UK context: the new Climate Change Bill
• New UK Climate Change Bill – 60% reduction by 2050 Targeted 5 yearly ‘budgets’ set at least 15 years ahead
• 26-32% cut by 2020• This is good but we need 80-90% cuts to
keep emissions below 450ppm • Target currently being reconsidered
Food/climate relevant legislation and initiatives (UK)
• Climate Change Agreements• Carbon Reduction Commitment (consultation)• Food Industry Sustainability Strategy and ‘champions
groups’ recommendations• Market Transformation Programme (radical
improvements in devt and uptake of energy efficient technology)
• Cabon Trust advice and support• Various Defra research programmes• Product ‘road maps’ on reducing impacts (eg. dairy
products• Developing consistent GHG labelling methodology (with
business and British Standards)• Thinking about personal carbon allowances (could food
be incorporated into this?)
UK policy
• Is this enough? Little direct focus on agriculture
• “Business running ahead of Government”
• Where is a coherent vision backed up with a plan?
Regulation
Legislation
Caps, quotas, thresholds, bans
Economic and fiscal
Voluntary agreements
Education, marketing & promotion
Social pressure
What new measures should we be considering?
What measures have worked for food & how can we strengthen them?
Policy instruments
Government: Some policy tools
Consumers

& uptake
7. What is the food industry doing?
Some food industry initiatives - agriculture
• Sustainable Agriculture Initiative (Nestle, Unilever, Danone, Kraft etc.)
• EUREPGAP
• Roundtables on sustainable soy / palm oil
• Not specifically climate focused
Food industry initiatives: retailers
• M & S: • £200 million ‘Plan A’• All operations carbon neutral by 2012• 25% energy cut; power stores with green electricity• Label and reduce air freighted produce• Tesco:
– Label and reduce air freighted produce– 50% energy cut in stores and DCs by 2020– £100 million renewables fund– Halve distribution emissions / case in 5 yrs
• Migros (Switzerland) – to introduce carbon labelling• French and Australian announcements
Food industry initiatives: manufacturers
• Tate & Lyle: biomass boiler to replace 70% fossil energy
• McCain's: up to 70% electricity needs from renewables including wind turbines and CHP plant running on biogas
• Cadbury’s: 50% absolute cut in carbon emissions by 2020
• Many others starting to carbon footprint their operations
• But focus of food industry is on efficiency rather than shifts in consumption.
Policy & business limitations
• Reluctant to question core business principles of Choice, Variety, Ubiquity, Repeatability, Convenience.
• And therefore scope for GHG reduction limited largely to technological change
• And technological change alone creates further behavioural changes
• Need not just to do things more efficiently but…• …Sell / don’t sell different stuff - ‘choice editing’
8. Observations and conclusions
Food’s impacts
• Climate change is happening• Food contributes to a significant proportion of
global GHG emissions• All stages in the supply chain contribute to
emissions• Agriculture most significant stage / meat and
dairy most GHG intensive food• Global food demand is moving in more GHG
intensive directions
• Climate change will affect global food supply - poor regions will suffer most
• Technology unlikely to get us to an 80% cut
• Consumption shifts needed too• Policy and govt beginning to tackle
problem but only from ‘efficiency’ perspective
Some major concerns
• 9 billion people on planet in 2050• Increase in numbers in absolute poverty AND
growing wealth in many parts of developing world• The poor will suffer most from climate change• An 80%+ cut in developed world GHGs needed • Tackle problems in isolation or as a whole -
atomised vs synthetic approach?
Land – the big challenge
• In the context of 9 billion on planet by 2050• What is the best use of global land so that:
– We are all fed adequately ...– At minimum GHG cost?– Stored carbon is not released?– Biodiversity is protected?– Other ethical non-negotiables upheld??
• Meeting Needs rather than demand - only feasible approach
In other words....
• Land to feed animals or to feed humans? • Land for feed production or for carbon
sequestration?• Land for animal rearing or for biomass
production?
• We need to collaborate globally and think strategically about how to make best use of land. But how?
Some research challenges• We need to:• Gain ‘good enough’ understanding of where the problem
lies by particular food type• Work out how far technology can get us • Improve understanding on what sorts of consumption
patterns (in the context of these technology changes) can help achieve reductions
• Understand more clearly how technological innovation influences behaviour and vice versa
• Frame the climate change debate in the context of other social, environmental and economic concerns
• LCA can inform policy but vagaries of consumer and business behaviour ALSO need to inform LCA
