The risk brought by climate change is one of the most severe challenges faced by human civilization in the 2 1 century, and it is also the focus of international and domestic ethics in East Asia. In September, 2020, China announced the goal of "peak carbon dioxide emissions, carbon neutrality", that is, China's carbon dioxide emissions will peak before 2030, and strive to achieve carbon neutrality before 2060.

Strive to reach the peak before 2030, which shows that China has taken the initiative to make more contributions to global climate change and established the image of a responsible big country. Deputy Director of China National Expert Committee on Climate Change said that it has become an international consensus to promote the governance process through global cooperation in the face of the security threat of climate change, a non-traditional field.

China took the lead in controlling the COVID-19 epidemic, and put forward a new carbon dioxide emission reduction target at this node, which is to make it clear to the world that China should take the road of green recovery and green transformation. The Director of the Climate Change Department of the Ministry of Ecology and Environment believes that the new national emission reduction targets provide a powerful starting point for promoting the high-quality development of the domestic economy and the construction of ecological civilization.

The goal of reaching the peak can't just be considered as reducing carbon dioxide emissions. In fact, this goal is the main driving force for China's high-quality development and all-round economic and social progress. To achieve the goal of peak shaving and even carbon neutrality, carbon dioxide emissions must be greatly reduced, which will continuously adjust and optimize the energy structure and industrial structure, and drive the strong growth of green industries.

Harm of excessive carbon dioxide emission;

1, Global Warming: Excessive carbon dioxide emissions will lead to global warming. Carbon dioxide gas has the functions of heat absorption and heat insulation. When it increases in the atmosphere, it will form an invisible glass cover, so that the heat radiated by the sun to the earth cannot spread to outer space, leading to the warming of the earth's surface.

2. Sea level rise: Sea level rise is one of the hazards caused by excessive carbon dioxide emissions. If the earth's surface temperature continues to rise, by 2050, the global temperature will rise by 2~4 degrees Celsius, and the icebergs in the north and south poles will melt in large quantities, leading to a substantial rise in sea level.

3. Harmful to human health: Excessive carbon dioxide emissions will cause harm to human health. Carbon dioxide will form a greenhouse effect, leading to global warming, melting glaciers, rising sea levels and other issues, thus endangering human health.
