Ukraine had the fifth-biggest total GHG emissions reduction from 2010 to 2020 and the sixth-largest drop of total CO2 emissions from 1971 to 2020. At the COP26 climate summit in Glasgow in November, President Volodymyr Zelensky said Ukraine’s goal is to reduce GHG emissions by 65% ââby 2030 and reach climate neutrality by 2060.

Sweden was among the top 10 nations in total CO2 emissions reductions from 1971 to 2020, CO2 emissions per capita from 2010 to 2020, and total GHG emissions from 2010 to 2020. Sweden has committed to cutting its net carbon emissions to zero by 2045, lifting its carbon emissions target since the Paris Agreement in 2015.

Earlier this month, Switzerland offered new legislation to halve GHG emissions by 2030 via a carbon dioxide tax. It did not include levies on air flights and car fuel in the legislation. Voters in June rejected government carbon-tax plans.

Italy cracked the top 10 in total GHG emissions reduction from 2010 to 2020. As a member of the European Union, Italy’s emissions goals are connected with those of the EU. The EU recently introduced new guidelines on cutting emissions by at least 55% by 2030 from 1990 levels.

> Total GHG emissions change 2010-2020: -35.13% — #7 largest decline of 88
The United Kingdom, birthplace of the Industrial Revolution, posted the seventh-largest decline in total GHG emissions from 2010 to 2020, and the ninth-biggest reduction of total CO2 emissions from 1971 to 2020. In April, the U.K. government said it intends to slash emissions by 78% compared with 1990 levels and is aiming to reach net zero by 2050.
