In fact, the carbon emission index regards the earth as a whole. For example, like a family, every country member releases carbon dioxide into the atmosphere, which will increase the greenhouse effect.

So everyone sat down together to discuss limiting carbon emissions, and according to the situation, each member was assigned a different share of emissions, that is, carbon targets. Zhao, chief engineer and professor-level senior engineer of Fujian Academy of Building Research, said that "carbon trading" is that a member emits too much carbon, which exceeds the standard, so it is necessary to buy indicators from people who emit less to control the emissions of the whole earth to the atmosphere.

Greenhouse gas emissions lead to an increase in the global average temperature, which leads to the melting of ice sheets, extreme weather, drought and sea level rise. This global influence will endanger human life and life. It is estimated that 5 million people die every year from air pollution, famine and disease caused by climate change and excessive carbon emissions.

If the current consumption pattern of fossil fuels is not changed, the death toll will rise to 6 million by 2030. More than 90% of them occurred in developing countries. The report evaluates the impact of climate change on human and economy from 20 10 to 2030.
