The development stage determines that China will achieve carbon peak in 2030 and carbon neutralization in 2060. The main reasons are that the economic foundation is not solid enough, the proportion of coal in the energy consumption structure is high, and there is still a lot of room for urbanization and industrialization. In the future, there is still a great demand for industrial products with large carbon emissions, such as steel, sludge and automobile; Carbon neutral will become an important driving force to promote the sustainable development of China's economy in the next 40 years, contributing more than 2% to the annual GDP growth; It needs to invest more than 120 trillion yuan in the energy system and drive up to 400 trillion yuan in related fields; The top priority of carbon neutralization is in the field of energy, from fossil energy (coal, oil and natural gas, accounting for about 70% of China's energy consumption) to clean energy dominated by solar energy, wind energy, hydropower, nuclear energy, hydrogen energy, etc; At the same time, the impact will be huge, involving transportation, construction, industry, agriculture, new materials, etc. The impact of carbon neutrality on China's economic development is no less than that of urbanization or WTO accession.
