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% ​​by 2030 and reach climate neutrality by 2060.

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.
