What is carbon emission?

Carbon emissions refer to greenhouse gas emissions, which cause the greenhouse effect and increase global temperatures. While the earth absorbs solar radiation, it also radiates heat to outer space. Its thermal radiation is mainly long-wave infrared rays of 3 to 30 μm.

When such long-wave radiation enters the atmosphere, it is easily absorbed by certain gas molecules with larger molecular weight and stronger polarity. Because the energy of infrared rays is low, it is not enough to cause the breakage of molecular bonds.

Therefore, no chemical reaction occurs after gas molecules absorb infrared radiation, but only prevent heat from escaping from the earth, which is equivalent to an insulating layer between the earth and outer space, that is, a “greenhouse”.

Certain trace components in the atmosphere absorb long-wave radiation from the earth, thereby retaining heat near the surface, leading to an increase in global temperatures, which is called the greenhouse effect. Today, climate issues are attracting global attention.

What does carbon emissions include?

The main source of carbon emissions is fossil fuels. Fossil fuel, also known as ore fuel, is a mixture of hydrocarbons or hydrocarbon derivatives, including natural resources such as coal, oil, natural gas, oil shale, oil sands, and flammable ice under the sea.

During the combustion process of fossil fuels, carbon is converted into carbon dioxide and enters the atmosphere, increasing greenhouse gas emissions. Fossil fuels such as coal, oil, and natural gas are the most widely used and are also the main source of carbon dioxide. Coal is very rich in carbon content, and the combustion of coal will emit a large amount of carbon dioxide.

According to calculations by relevant units, the amount of carbon dioxide emitted by my country’s coal fuel accounts for more than 80% of the amount of carbon dioxide emitted by fossil fuels, accounting for half or even more of China’s total greenhouse gases.

China is the world’s largest emitter of greenhouse gases. In 2019, China’s total greenhouse gas emissions accounted for more than 27% of global emissions, which exceeds the total of the Organization for Economic Cooperation and Development (OECD) countries.

According to statistics from the World Resources Institute, China’s carbon emissions mainly come from electricity, construction, industrial production, transportation, agriculture and other fields. Among them: energy and electricity account for the largest proportion, accounting for about 40%; followed by the construction field, accounting for more than 20%; industrial production, transportation, and agriculture each account for 5% to 10%.
