INSIGHT BRIEF: Accounting for impact: Refocusing GHG Protocol scope 2 methodology on ‘impact accounting’

 September 22, 2022 

The GHG Protocol (GHGP) — the world’s leading source of carbon accounting standards — has motivated sweeping clean energy investments and carbon reduction or neutrality goals from corporations and institutions worldwide. But are the emissions reductions currently being counted on paper actually translating into real-world environmental impact?

In WattTime’s Accounting for Impact report, we explore the GHGP’s current methods for measuring Scope 2 emissions and propose a new methodology to better align traditional GHG accounting with science-based decision-making tools. Our proposed solution focuses on measuring actual induced emissions caused by electricity consumption and the avoided emissions impact of renewable energy generation using marginal emissions rates. This approach can more effectively and consistently capture what GHG accounting ultimately should be about: measuring progress toward system-wide emissions reductions. By refocusing GHGP’s Scope 2 methodology toward this goal using impact accounting, corporate and institutional sustainability leaders can arrive at higher-impact choices and investments that help them reach a true state of ‘impact neutral’.
