Beijing has actively promoted the pilot construction of low-carbon cities based on the principle of reducing development，which has laid a good foundation for low-carbon development. Especially since 2013，Beijing has taken unprecedented and powerful measures to promote air pollution control，with the improvement of air quality as the core goal. Through industrial relief and regulation，clean energy transformation，strict supervision and assessment and other measures，Beijing has continuously reduced air pollutants，carbon emission intensity and total amount. Its low-carbon development experience is mainly reflected in the coordinated emission reduction of air pollutants and carbon dioxide driven by air pollution prevention and control，as well as the systematic and structural carbon reduction in industries，energy，transportation and other fields driven by institutional constraints and market mechanisms. The 14th Five Year Plan period is a critical period for China to reach the peak of carbon and explore carbon neutralization. Beijing has the responsibility and ability to play an exemplary role. In view of the current dilemma of low-carbon development in Beijing，we can ensure the continuous decline of carbon emissions and lead the national carbon neutralization process in the future from the aspects of improving the level of electrification，accelerating the use of clean energy，controlling carbon emissions by regions and sub sectors，taking into account low-carbon technologies and ecological functions.
