Where do urban CO2 emissions come from?

Since the 20th century, with the rapid development of industry, people's living standards have been continuously improved, and they have gradually evolved from the past to today's automobile travel. And people's society is also undergoing drastic changes, especially the climate problem, the most obvious of which is the greenhouse effect.

It's particularly serious. And there are a lot of fossil fuels every day.

As well as exhaust emissions, large amounts of carbon dioxide are generated.

The greenhouse effect and the amount of carbon dioxide that people exhale is very highIn the middle of the city, the most important of urban carbon dioxide is factory exhaust emissions and fossil fuel combustion. <>

Smell, know that the city is relatively central, there are many factories, of course, the most important thing is transportation.

Relatively developed. Everybody has a private car and a lot of buses there, and they emit a lot of tailpipe emissions every day, but the most important thing to go back to be with you is carbon dioxide, because tailpipe emissions produce carbon dioxide, fossil fuels also produce carbon dioxide, and many factories emit a lot of carbon dioxide every day, which is the main cause of our greenhouse effect. However, since the Industrial Revolution, China's urban population has increased relatively much, and some modern means of transportation and a large number of factories have been born, and a large number of exhaust gases and carbon dioxide are emitted every day, which is the first of urban carbon dioxide.

The emission sources of the urban greenhouse effect are mainly electricity, heat, cold, steam, traffic and waste water, etc., the most important is the period of emissions, because the traffic in the city is very busy, there are a large number of vehicles passing by and using every day, so the carbon dioxide content in the exhaust produced by fossil fuels is very high, which also leads to a very drastic increase in carbon dioxide。Nowadays, low-carbon emission reduction is also being achieved, many people are doing public travel, and now, the greenhouse effect has become an international problem, and every country is actively solving the problem of carbon dioxide emissions and a lot of exhaust gases. <>

Therefore, because the population of the city is relatively concentrated, and the industry and transportation industry are relatively developed, but the only thing that is lacking is the relatively small amount of green plants such as farmland and crops, which leads to the relative concentration and high density of carbon dioxide.

Carbon dioxide emissions in cities, mainly due to the increase in carbon dioxide in the air due to the combustion of fuels.

1. Automobile exhaust emissions are the main source of carbon dioxide release. Since the reform and opening up, people's living standards have been continuously improved, and basically the car has become the main means of transportation for people. There are countless cars in the city, and the roar of motors can be heard everywhere in the streets and alleys.

Cars are powered by oil, which releases a large amount of carbon dioxide when burned, so cars are still the main force of carbon dioxide release in cities. <>

2. The combustion of natural gas and coal gas also releases carbon dioxide. In the city, due to space constraints, most people's main cooking method is to rely on natural gas or coal gas for heating, and at this time, the combustion of natural gas will release a part of carbon dioxide. But this source of carbon dioxide is inevitable, and it is inevitable that human factors are inevitable.

Every day, you need to make a fire for cooking, and as long as there is cooking, there will be carbon dioxide output. There are many more sources of CO2 than that, and some smelters emit more CO2. <>

Nowadays, due to the serious exceedance of carbon dioxide emissions, the Beichuan iceberg has melted, and many animals have been displaced, which is a wake-up call from nature for human beings. In today's severe natural environment, we should drive less private cars and promote green travel, and in our daily lives, we should walk more and drive less. In addition, we need to plant trees and cultivate natural oxygen for nature in response to the response of the state, and for the safety of the next generation of children and grandchildren, we should refrain from driving private cars as much as possible.

In summary, the main emissions of carbon dioxide in cities are factory and car exhaust, so in order to create a better living environment, we should actively participate in tree planting activities, and we should refrain from driving in our daily lives.

Urban carbon dioxide emissions are mainly due to people's production and life, as well as petroleum processing, coking and nuclear fuel processing industries, electricity, heat production and industry.

Vehicle exhaust emissions are the main source of CO2 release. The combustion of natural gas and coal gas also releases carbon dioxide.

People breathe, factories operate machines, car exhaust emissions on the road, garbage disposal is generated.

The main carbon dioxide emissions are the combustion of fossil fuels such as oil, natural gas, and coal.

In fact, there are more carbon dioxide emissions, such as plant respiration and humic acid fermentation; fermentation and decay of organic matter; forest fires, volcanic eruptions, etc.; Fossil fuels, of course, there are others in addition to these. However, in response to the issue of greenhouse gas and carbon dioxide emissions, it is necessary to clarify the current emission structure.

Carbon dioxide is a kind of carbon oxide, the chemical formula is CO2, at room temperature and pressure is a colorless and odorless or colorless and its aqueous solution is slightly sour gas, the gas is not only a more common greenhouse gas, but also a component of air, occupying the total volume of the atmosphere.

The carbon dioxide emissions in the city are from the exhaust of cars and the exhaust of major factories, and the rest is the carbon dioxide exhaled by people and animals.

The carbon dioxide emitted in cities mainly comes from the waste air of factories and the exhaust emissions of vehicles.

Combustion of petroleum gas and natural gas emissions during home cooking;

Fuel combustion in the process of driving the car also emits a lot of carbon dioxide;

Both humans and plants produce carbon dioxide through respiration.

There is a lot of carbon dioxide in cities, most of which comes from the exhaust gas emitted by automobiles, the exhaust gas emitted by industrial production processes, and the carbon dioxide emitted by human breathing.

It is from agriculture, industrial production, various energy plants, solid waste, sewage, wastewater, and automobile exhaust.
