Climate change in Sweden has received significant public and political attention. Mitigating its effects has been high on the agenda of cabinets of the Governments of Sweden from 1996 through 2021. Sweden aims for an energy supply system with zero net atmospheric greenhouse gas emissions by 2050. In 2014 and 2016, Sweden was ranked #1 in the Global Green Economy Index (GGEI), because the Swedish economy produces relatively low emissions. Sweden's winter temperature is predicted to increase by as much as 7 °C (45 °F). This will increase the percentage of precipitation that comes from rain instead of snow. The Baltic Sea could see a surface water temperature increase of up to 4 °C (39 °F). This will decrease sea ice cover by the end of the century.
