Climate change is a global problem facing mankind. With the emission of carbon dioxide in various countries, greenhouse gases have surged, posing a threat to life systems. In this context, countries around the world have reduced greenhouse gas emissions in the form of global agreements, and China proposed the goal of carbon dioxide emission peak and carbon neutrality. The peak of carbon dioxide emissions means that China promises that carbon dioxide emissions will not increase before 2030, and will gradually decrease after reaching the peak; Carbon neutrality means that enterprises, groups or individuals calculate the total amount of greenhouse gas emissions directly or indirectly generated in a certain period of time, and offset their own carbon dioxide emissions by planting trees, saving energy and reducing emissions, so as to realize carbon dioxide? Zero emissions? .
Carbon emissions are closely related to economic development, which requires energy consumption. The proposal of this goal means that our production mode and lifestyle will undergo profound changes in the future. At present, all provinces and cities in China are making corresponding plans for the peak of carbon dioxide emission. In Guangdong, especially in Guangdong-Hong Kong-Macao Greater Bay Area, the foundation of air defense and joint defense is relatively early. The early formation of the joint prevention and control mechanism of air pollution in the Pearl River Delta and the subsequent establishment of the joint prevention and control mechanism of Guangdong, Hong Kong and Macao in the Greater Pearl River Delta will help Guangdong to take the lead in achieving the peak of carbon dioxide emissions.
Global climate change is a major challenge facing mankind in the 2 1 century. China is the largest carbon emitter in the world. Coping with climate change is related to the overall situation at home and abroad, and it is related to the overall situation and long-term development. It is an important starting point for promoting high-quality economic development and ecological civilization construction, and an important field for participating in global governance and adhering to multilateralism. Since 2020, China has put forward strong goals and visions to deal with climate change on several major international occasions, and published a series of initiatives and viewpoints, which have pointed out the way forward for green and low-carbon transformation and injected new momentum into global climate governance.
