Twenty Years of Climate Policy: G20 Coverage and Gaps

The analysis of G20 climate policies between 2000 and 2019 reveals that while the number of mitigation policies has increased, significant adoption gaps persist across all sectors. Approximately half of the 50 identified key policy options are not widely adopted, leaving at least one-tenth of G20 emissions completely uncovered by policy.

• Between 2000 and 2019, the number and coverage of climate change mitigation policies in the G20 increased, yet approximately half of the 50 identified key policy options remain inadequately adopted.
• Policy adoption is specifically low for measures targeting the phase-out of coal and oil, energy reductions in electricity and heat supply, industrial process emissions, industrial fuel switching, urban planning for retrofits, renewable energy for building heating/cooling and cooking, the removal of fossil fuel subsidies, and carbon dioxide removal.
• Policy adoption gaps are present in every sector, resulting in at least 10% of G20 emissions being entirely uncovered by policies.
