In 2022，China continues to consolidate and expand the achievements of the three major campaigns of air pollution，water and land pollution. China also takes the task of pollution reduction and carbon reduction as the starting point，and coordinates the three major tasks of pollution control，ecological protection and coping with climate change. Meanwhile，China strongly promotes green，low-carbon and high-quality development. The air is fresher，the water is clearer，the soil is safer，and the ecology is more beautiful. The ecological and environmental problems have been solved in an efficient way. The “Winter Olympic Blue” and “Beijing Blue” have been praised by the international and domestic society. At the same time，however，the global ecological environment deficit has continued to expand，and the four key indicators of climate change，namely greenhouse gas concentration，sea level rise，ocean heat and ocean acid level，have all set new records. The problem of global sustainable development has become more and more urgent and challenging. Under the pressure of the domestic economy，China’s ecological environment protection faces the urgent challenge of how to combine green，low-carbon and high-quality development with the goals of stability and security of social and economic development.
