摘要

Ambitious carbon neutrality plans are required to achieve the 1.5 ℃ goals of global warming mitigation under the 2016 Paris Agreement.For instance,compared with the business-as-usual case without any policy intervention,China needs to reduce carbon emissions by more than 90% and cut energy consumption by over 39% to achieve the 1.5 ℃ goals,which would cost 2.8-5.7% of its gross domestic product(GDP)by 2050.'The European Union(EU)has been active in carbon reduction for decades.A recent study showed that 78% of 327 studied cities in the EU aimed to reduce carbon emissions by 47%,but these cities need to double their efforts by 2050 to reach the goals of the 2016 Paris Agreement."These actions toward carbon neutrality are challenging,but the global league is continuing its efforts.New global collaboration and decarbonization pathways are being formulated as exemplified by the agreement of a 30% cut in methane emissions by 2030 signed by more than 100 countries.'
