Policy Brief: Carbon emissions in public markets

Stock exchanges can play an important role in promoting emissions reductions in their markets. This policy brief provides a unique analysis by examining the Scope 1 carbon emissions of the top 100 companies by market capitalization listed on each of the G20’s major stock exchanges. Focusing on companies that are listed on exchanges (rather than a country level view that is more traditionally presented) allows exchanges to understand the state of carbon emissions associated with their largest issuers. This data can serve as a benchmark for exchanges in their efforts to promote net zero emissions among their listed issuers.
