The authors conclude this issue of Amplify by analyzing systems for governing greenhouse gas (GHG) emissions in markets in the US. They argue that public-private partnerships (PPPs) have the potential to fill the void in market governance left by the failure of the government to enact comprehensive climate change legislation. The authors highlight the Science Based Targets initiative (SBTi) as a tool that provides companies and other organizations with the means to make specific, credible plans to achieve decarbonization. They argue that aligning PPPs with SBTi target setting would be an effective mechanism to accelerate carbon emissions reductions.
