China has the largest population in the world. With the rapid development of industry and manufacturing, Chinese people's food, clothing, housing and transportation will directly or indirectly produce carbon emissions. Therefore, China is also the largest carbon emitter in the world. At present, coping with climate problem has become the greatest challenge for China to realize socialist modernization, but it also brings great opportunities for urbanization, agricultural and rural modernization and green industrialization. China has set a goal of achieving peak carbon by 2030 and carbon neutralization by 2060. In this context, energy-saving and carbon-reduction work of provinces and cities is facing new tasks and higher requirements. Under the “two carbon” goal, implementing dual control over energy consumption intensity and total amount, promoting energy conservation and consumption reduction, and promoting high-quality development are important ways to solve resource and environmental issues. Industrial and urban and rural construction are two major areas of energy use. Provincial governments have issued relevant action plans to control carbon emissions and embark on a green and high-quality development path.
