The source of carbon emissions in 2019
The year is in my sea, and the world is researching the source of carbon emissions, in order to find out its situation, in order to find ways to deal with it.

This is the time, considering the data of all parties, we can get various sources of carbon emissions. One is the combustion of energy. All kinds of fossil fuels, such as coal, oil, gas, etc., are burned to release carbon for energy supply, and their amount is quite huge, accounting for a very high proportion of the total emissions. Because industrial production, transportation operation, people's livelihood heating and other things depend on this energy, its carbon emissions are an important source.

Second, industrial processes are also one way of carbon emissions. In various manufacturing industries, such as iron and steel smelting, cement firing, and chemical synthesis, during production, due to chemical reactions, etc., carbon escapes in different forms and enters the atmosphere. Although its proportion is slightly lower than that of energy combustion, it should not be underestimated.

Furthermore, agricultural activities also involve carbon emissions. When livestock are raised, greenhouse gases such as methane are released during their digestion and respiration, and measures such as farmland fertilization also cause carbon-related gas emissions such as nitrous oxide. Although the amount of a single source may not be alarming, it adds up to a lot, and it also has its place in the total carbon emissions.

There is also land use change related to forestry. Cutting down forest land and converting land to other uses can reduce the carbon sequestration energy of vegetation and gradually release the carbon stored. Proper forestry activities can increase carbon sinks, but if they are not well managed, carbon emissions will increase.

Looking at the sources of carbon emissions in 2019, it can be seen that energy combustion is the top priority, and industry, agriculture and land use also have their own impacts. To control carbon emissions, we must focus on various sources, promote clean energy, change industrial processes, improve agriculture, and sequester carbon in forest protection. Only then can we hope to reduce carbon emissions, maintain the stability of the environment, and promote the sustainability of the world.
