Twenty Years of Climate Policy: G20 Coverage and Gaps

This research paper by the NewClimate Institute analyzes the adoption of climate change mitigation policies within the G20 from 2000 to 2019, identifying significant policy gaps across all sectors that leave a portion of emissions uncovered.

• Between 2000 and 2019, the number and coverage of climate change mitigation policies in the G20 increased, yet significant adoption gaps persist. Approximately 50% of the 50 identified key policy options for a comprehensive sectoral package are not widely adopted, resulting in at least 10% of G20 emissions remaining completely uncovered by policies.
