Very quick background
Books
A sustainability consultancy largely
focussed largely on supply chains
BT, Booths, Taylor Wimpey, lots of SMEs
in many industries, public sector,
Lancaster University, Eden Project,
Science Museum, Guardian, community Research
projects ...

Most supply chains are complex and opaque Our understanding can never be exact but it can be ‘good enough’
Bringing transparency to supply chains

horsemeat
scandal
UK government increasingly understands embedded impacts
We need an up to date understanding of what ‘responsible’ looks like

Direct Tier 1 Tier 2 Tier 3 Tier 4PAS 2050 – Review of methods “Experts highlighted particularly two weaknesses of PLCA: cost and labour intensity of carrying out a PLCA and the system boundary problem … “system cut-off” is unavoidable in PLCA …The cut-off criteria suggested by ISO can be misleading and do not provide a satisfactory basis for a transparent system boundary selection…. The (resulting) truncation error is potentially very large. …” “…This is further aggravated when restrictions are imposed on the budget as typical in simplified PLCA approaches. Such simplified approaches usually fail to reliably reproduce results from detailed PLCA . However, only simplified PLCAs work under tight budget constraints required for the PAS to be applicable to organisations of all sizes. This seriously limits the usefulness of PLCA for the PAS development.”
Input Output Analysis Looks at the whole economy divided into industry sectors.
Input Output Analysis Demand for products stimulates output across the economy….
Input Output Analysis …. causing both direct and indirect emissions…
Input Output Analysis …. the ripple effects are endless…
Input Output Analysis …. the ripple effects are endless… but can be modelled as a complete system… …without systematic underestimation
A hybrid methodology is usually the most
practical way to get a reasonable
understanding
+Summary questions • What does responsible look like in 2013? • How can standards ensure the real priorities are addressed – within a finite resource? • How can standards work for small players? • How can supply chains become transparent • How can standards be greenwash proof?
Thank you for listening
