1, industrial waste gas emission: In the process of industrial production, many processes will produce a lot of waste gas, such as carbon dioxide, methane, nitrous oxide and so on. With the development of industry, the emission of waste gas has increased year by year, becoming one of the important sources of greenhouse gases.
2. Increase of greenhouse gases: Greenhouse gases refer to gases that can absorb radiation from the earth's surface, such as carbon dioxide, methane and nitrous oxide. When gas is discharged into the atmosphere, it will hinder the emission of radiation on the earth's surface, lead to the increase of the earth's surface temperature, and form a global warming phenomenon.
3. Important reasons: Industrial waste gas emissions are one of the important reasons for the increase of greenhouse gases, and their emissions account for a considerable proportion of the total greenhouse gas emissions. With the development of industry and the improvement of people's living standards, industrial waste gas emissions are increasing, which has an important impact on global climate change.
