Reduction in greenhouse gas emissions from national climate legislation

Nature Climate Change, Published online: 13 July 2020; doi:10.1038/s41558-020-0831-z Climate change laws are shown to reduce national CO2 emissions by 0.78% in their first three years and 1.79% in the longer term. These reductions add up to 38 GtCO2 of avoided emissions for 1999–2016—equal to a year of CO2 emissions.
