This document outlines a clear, rigorous methodology for carbon counting to ensure transparency and accuracy in carbon accounting. It addresses the importance of recognized standards, such as PAS 2050 and the Carbon Trust Standard, while detailing the processes involved in site and product footprinting. Key components include numerical impact statements, boundary definitions, and verifiability for effective GHG emission management. The aim is to provide organizations with the tools necessary to measure, reduce, and communicate their carbon footprints effectively.

Carbon footprinting tools • Carbon footprinting; an introduction for organisations • On-site surveys; footprinting module • On-line footprint calculator • Training event
The Carbon Trust Standard • Measurement based on GHG Protocol • All organisations must have achieved a reduction • Absolute (tCO2) or • Relative -2.5% (tCO2/widget) • 2 year renewal cycle • Renewal will require progress since initial certification • 65 organisations certified • Certified organisations can display logo on marketing materials
Carbon Trust activity • Site and company footprinting • Carbon Trust Standard • Product footprinting • PAS 2050 • Carbon Label Company
Developing product footprinting methodology • Developing standards to: • Measure; • Reduce; and • Communicate • the GHG emissions from goods & services • Product footprinting • Reduction planning • Communication (including labelling)
Walkers re-certification • Nearing 2-year anniversary of original footprint launch • Recertified footprint: shows 7% reduction on 2007 • Mix of supplier & Walkers internal initiatives • Saved £400,000, to reinvest in carbon-saving initiatives • New label appearing in April/May • www.walkerscarbonfootprint.co.uk
International Update: Standards We are closely involved in the ongoing international work
International Update: Projects • US: Coke announced as new partner • US: Tropicana results exclusive in NY Times • Generated 78 follow-on stories with 3.5 million online page impressions • PepsiCo committing to footprint further brands • China: Footprinting trials about to begin with ~3 product categories • Sugar • Clothing • Toys • Possibly others to follow • Coordinating with other country initiatives e.g. Germany, Japan, Korea
Requirements for Carbon Accounting • To provide a clear and unambiguous statement of impact; • Numerical • Recognised methodology • Clear statement of boundaries • Verifiable • Allows; • Progress to be assessed • Comparisons to be made • Efforts to be accurately focused • Myths to be uncovered
