SBTi and RE100 provide direction for companies working toward decarbonization, and revisions to strengthen these standards are currently underway. In addition, the GHG Protocol—the global standard for corporate greenhouse gas (GHG) emissions accounting and reporting—is also being updated.
These standards not only have a significant impact on corporate activities but are also closely linked to the initiatives of national and local governments. Below are publications and events by Renewable Energy Institute on latest developments in each of these international initiatives.
