CHAPEL HILL, N.C. (Callaway Climate Insights) — A new study shows how investors can prod companies to get their Scope 3 greenhouse gas emissions under control.
Reducing those emissions is a crucial part of fighting climate change. Scope 3 emissions, which are what is produced by the supply chains a company uses, represent the lion’s share of all corporate greenhouse gas emissions—75%, according to a World Resources Institute estimate. They are to be distinguished from Scope 1 emissions (those a company produces directly from its operations) and Scope 2 emissions (those produced by the electricity a company has purchased).
Despite Scope 3’s crucial importance, most companies only report emissions in Scopes 1 and 2.

As a result, investors are largely in the dark as to which companies are the biggest contributors to global warming.
In fact, as I pointed out in this space earlier this year, investors actually are being misled: That’s because companies with the highest ESG ratings based on their Scope 1 and 2 emissions tend also to be the biggest offenders when it comes to Scope 3 emissions.
