SO2 emission trend
We measure the average annual growth rate of sulfur dioxide (SO2) emissions over the years 2014 to 2023 and adjust for economic trends to isolate change due to policy effort rather than economic fluctuation. A score of 100 indicates a country is cutting emissions by at least 8.4% per year, and a score of 0 indicates that a country is increasing emissions by 8.4% per year or more. Data come from the Community Emissions Data System.
