The current situation of air pollution in China: More than 1 billion people in cities around the world are threatened by air pollution. The World Health Organization estimates that 8 million people worldwide will die from air pollution by 2020.
In China's 11 largest cities, soot and fine particulate matter in the air kill 50,000 people every year and 400,000 people become infected with chronic bronchitis. To a certain extent, urban living is deviating from the health goals that people are pursuing. (1) Current status of sulfur dioxide emissions:
With the rapid development of China's economy, coal consumption is increasing. National coal consumption increased from 100 million tons in 1990 to 100 million tons in 1995, and total sulfur dioxide emissions increased sharply with the growth of coal consumption. By 1995, the country's total sulfur dioxide emissions reached 23.7 million tons.
Among the various sources of sulfur dioxide emissions, power plants and industrial boilers account for 70% of emissions, becoming major emitters, and the percentage of sulfur dioxide emitted from various pollution sources is as follows: 12% for civil stoves, 11% for industrial kilns, 34% for industrial boilers, 35% for power station boilers, and 8% for others. (2) Status quo of soot and dust emission:
In 1995, the total amount of soot emitted by coal-fired coal in China was 14.78 million tons, of which more than 70% were emitted from thermal power plants and industrial boilers. In the emissions of thermal power plants, local power plants basically use inefficient dust collectors, and the soot emitted per ton of coal is 5 10 times that of national power plants, accounting for 65% of the total emissions of power plants. In 1995, the national industrial dust emissions were about 6.39 million tons.
Thereinto. Dust emissions from steel production account for 15% of the total, and dust emissions from cement production account for 70% of the total. In the dust exhaust of cement production, the dust emission of local cement plants accounts for 80%, which has become the main emission source of industrial 12 dust.
In recent years, the rapid development of township industry in 1996 showed that in 1995, the emissions of sulfur dioxide, soot and industrial dust accounted for the total of the national industrial sulfur dioxide, soot and industrial dust emissions in that year2% and. The discharge of industrial pollutants from towns and towns has become an important factor in China's environmental pollution.
3) Current situation of motor vehicle exhaust pollution: Since the 80s, driven by economic growth, the number of motor vehicles in China has grown rapidly. By 1995, the number of cars in the country had exceeded 10.5 million, an increase of 4.2 million over 1990.3 The total emissions of nitrogen oxides, carbon monoxide and hydrocarbons emitted by automobiles have increased year by year.
Due to the dense population of the city and the relatively large volume of transportation, the proportion of motor vehicle exhaust pollution in urban air pollution is also rising.

Data collected for the United Nations by the U.S. Department of Energy's Center for Carbon Dioxide Information Analysis (CDIAC). The top 10 countries account for the world's total emissions. Carbon dioxide (Molecular Formula:
CO2) is a common compound in the air that consists of two oxygen atoms linked by a covalent bond with one carbon atom.

Carbon dioxide emissions are the average greenhouse gas emissions generated during the production, transportation, use and ** of a product. In household electricity, carbon dioxide emissions (kg) are equal to the number of kilowatt-hours of electricity consumed multiplied, i.e. 100 kilowatt-hours of electricity used is equivalent to about kilograms of carbon dioxide emitted.
Modern advocates a low-carbon lifestyle, as far as possible to lower greenhouse gas (carbon dioxide-based) emissions, water-saving, electricity-saving, fuel-saving, gas-saving, slag disturbance are low-carbon lifestyles.
People can reduce carbon emissions in various ways: driving less private cars, insisting on climbing buildings instead of Dan, choosing to turn off computers when not in use, etc., and "low-carbon life" is quietly emerging.
Climate warming is actually caused by the accumulated carbon emissions in the history of developed countries, and people should consciously live a low-carbon life for the sake of the common home of mankind.

Carbon dioxide emissions per capita, i.e., the average per capita carbon dioxide emissions in a certain area.
In 2018, China's per capita carbon emissions were about tons, while the world's per capita carbon emissions were about tons, and China's per capita carbon emissions were about 5.3 of the world. [1]

Summary. Hello! In 2022, the per capita carbon dioxide emissions will be greater than 7 tons, which is twice the global average per capita and has exceeded developed countries such as the United Kingdom and France.
With the continuous development of the economy and society, it will also drive the continuous growth of energy consumption, and the pressure of greenhouse gas increase is huge.
You're on a good stool! I have found out that the per capita carbon dioxide emissions in 2022 will be greater than 7 tons, which is twice the global per capita average and has exceeded that of developed countries such as Britain and France. With the continuous development of the economy and society, it will also drive the continuous growth of energy consumption, and the pressure on the increase of greenhouse gases is huge.
The realization of the goal of carbon peak and carbon neutrality is faced with many challenges, such as large emission reductions, heavy transformation tasks, and tight time windows. In 2022, China's total greenhouse gas emissions will be 13.9 billion tons of carbon dioxide equivalent, accounting for 27% of total global emissions. The total carbon dioxide emissions are 11.6 billion tons, of which about 10.1 billion tons of carbon dioxide are emitted by energy activities, accounting for about 30% of global energy emissions.
China's per capita greenhouse gas emissions have reached 10 tons, about double the global per capita level.
Because the United States is an industrial country, with a high degree of industrialization and many thermal power plants, the carbon dioxide emissions of photovoltaic power plants in the United States stand at a quarter of the total emissions of power plants in the world. >>>More

The carbon dioxide layer can transmit light waves, but no longer reflect long waves, so that heat is no longer dissipated, and it plays a role in heat insulation. This is the case with global warming.
