What you want to ask is to deepen the understanding of leading cadres at all levels on the peak of carbon dioxide emissions and carbon neutrality. Importance, urgency, scientificity and systematicness. According to official website of the State Council, the State Council has trained leading cadres at all levels in stages and at different levels to deepen their understanding of the importance, urgency, scientificity and systematicness of peak carbon dioxide emission and carbon neutrality. The peak of carbon dioxide emissions means that at a certain moment, the carbon dioxide emissions no longer reach the peak, and then gradually fall back. Carbon neutrality means that each subject calculates the total amount of greenhouse gas emissions in a certain period of time, and offsets its own emissions in various ways to achieve zero carbon dioxide emissions.
