World Business Council for Sustainable Development (2002)

“There is a growing awareness that

shareholders’ value is enhanced by

increased corporate social and

environmental responsibility.”

“Corporate sustainability reports and

sustainability ratings are increasingly

used as key information for investment and

lending decisions.”

Challenges remain…

World Business Council for Sustainable Development (2002)

“There is little comparability among the various sustainability rating questionnaires sent to companies.”

“A key challenge remains reporting on the links between sustainability and the bottom line.”

Extend reporting boundaries

World Business Council for Sustainable Development (2002)

“Business will increasingly be expected to report across the value-chain, i.e. on supplier- and consumer-related impacts of activities, products and services.”

Trucost & Defra (May 2006)

Reporting on direct and indirect KPIs

“The Government expects businesses to report on their significant environmental impacts whether they are direct or indirect.”

“Businesses are likely to derive benefit from positively influencing their indirect environmental impacts.”

Trucost & Defra (May 2006)

Indirect (environmental) impacts

Supply Chain Impacts (upstream)

Direct Company Impacts (on-site)

Downstream Impacts

Energy

Water

Raw materials

Logistics

Products in use

Product disposal

Boiler emissions

Car fleet emissions

Manufacturing emissions

Landfill waste

Recycling rate

“… there is still a lack of quantification in most reporting. … the majority of reports lack depth, rigour or quantification.”

“Most business will have supply chain impacts that they should understand and consider reporting. There is no single, quantifiable measure that companies can use as a Key Performance Indicator for the effect of their upstream supply chain on the environment.”

Trucost & Defra (May 2006)

The problem of quantification

Principle 1: quantitative

Principle 2: relevant & reliable

Principle 3: comparable

Principle 4: complete

SD Reporting Principles

TBL Accounting

without boundaries

TBL Accounting

without boundaries

Where to draw the boundary?

e.g. total emissions (direct

plus indirect)

e.g. direct (on-site) emissions

e.g. purchases of a company

How to allocate

along a supply chain?
