Prof Roland Clift, Centre for Environmental Strategy (CES)
Industrial ecology asks us to understand how the industrial system works, how it is regulated, and its interaction with the biosphere; then, on the basis of what we know about ecosystems, to determine how it could be restructured to make it compatible with the way natural ecosystems function.

Industrial Ecology is an area of applied research which brings together:
• Engineering• Science• Economics• Behavioural Sciences• etc..etc.

ACCOUNTING METHODOLOGY FOR EACH MATERIAL STOCK IN MFA
Prof Roland Clift, Centre for Environmental Strategy (CES)
STOCKS AND FLOWS (1):
A flow variable is one that has a time dimension or flows over time (like the flow through a stream).
A stock variable is one that measures a quantity at a point in time (like the water in a lake).
Income is a flow: wealth is a stock.
(adapted from “Economics” by Samuelson and Nordhaus).

FOREGROUND SYSTEM:Set of processes whose selection or mode of operationis affected directly by decisions based on the study.
BACKGROUND SYSTEM:All other processes which interact directly with the foreground system, usually by supplying material or energy to the foreground or receiving material energy from it. A sufficient (but not necessary) condition for a process or group of processes to be in the background is that the exchange with the foreground takes place through a homogeneous market.

ASSUME - other products from Foreground are used in Background
- other Functional Outputs from Background unchanged
THEREFORE - other products from Foreground displace activities in Background and so
avoid some burdensTOTAL INVENTORY is then:
DIRECT BURDENS from ForegroundplusINDIRECT BURDENS from Background,

• 2 million tonnes per annum (UK)
• Target to recycle 4kg/head/year (across EU)
• In UK producers pay according to their current market share in a collective scheme
• Recycle what? (How?) / Reuse?

POLICY RESPONSE: LONG TERM
Move to sustainable materials and energy
• Pressure from:
- Legislation /fiscal measures
- Customers
- Scarcity(?)
Prof Roland Clift, Centre for Environmental Strategy (CES)
POLICY RESPONSE: SHORT/MED TERM
•(Extended) Producer Responsibility
-Initially concentrating on waste management
•Integrated Product Policy
-Will cover whole life cycle including ‘use’ phase
Prof Roland Clift, Centre for Environmental Strategy (CES)
EXTENDED PRODUCER RESPONSIBILITY (EPR)
• ‘an environmental policy approach in which a producer’s responsibility for a product is extended to the post consumer stage of the product’s life cycle.’ (OECD)
Prof Roland Clift, Centre for Environmental Strategy (CES)
WHAT EPR AIMS TO DO…
• Increase reuse and recycling to reduce waste to landfill
• Effect up-stream actions to combat down-stream problems
• Make producers financially responsible for ‘their’ waste

ADDED VALUE = Sales price of outputs – costs of (inputs + ancillaries + energy)

Where does this point?A redefinition of quality or luxury…
EQUITY includes:
– Equity along the supply chain– Equity of access to “environmental services” between
affluent and poor
This requires consumption in affluent societies to have low environmental impact per dollar spent and to provide social and economic benefits along the supply chain:
