Reasons for setting up World Car Free Day

The reason for setting up World Car Free Day is that we should pay attention to low carbon, environmental protection and sustainability when developing. Automobile exhaust emission is a big problem in environmental protection, so every year, on World Car Free Day, we will encourage everyone to choose an environmentally friendly way of travel as much as possible. The following are the reasons for setting up World Car Free Day.

Reasons for the establishment of World Car Free Day 1 World Car Free Day was born in France in 1998. On September 22 of that year, citizens of 35 cities in France voluntarily gave up their private cars on this day. A year later, on the same day, 66 French cities and 92 Italian cities took part in the "Car Free Day" activity. Then in 2000, the car-free day initiative was incorporated into the EU's environmental protection policy framework. September 22nd became "European Car Free Day" and "International Car Free Day", and 1488 cities around the world joined this activity.

Experts have calculated that a car-free day in China can save 33 million liters of fuel, reduce about 3,000 tons of harmful gas emissions and protect hundreds of people from traffic accidents. In addition, automobile exhaust contains solid particles such as carbon monoxide and nitrogen oxides that have adverse effects on human body, especially leaded gasoline, which is more harmful to human body.

About the emission of automobile exhaust into the air, it is called photochemical smog abroad, which will hurt people's eyes, make them ache or make people have a dry cough and sore throat. If "Car Free Day" is held for one day, how much exhaust emissions will this city reduce? Of course, car-free day does not mean that there are no cars on the street, but people who travel try to choose buses or bicycles. As the most basic public transport in the city, it is impossible to implement car-free day.

The negative effects of cars on people can be said to be various, including environmental pollution, energy consumption, traffic congestion and so on. But we can't live without cars.

World Car Free Day is not to refuse cars, but to arouse people's attention to environmental problems.

Reasons for the establishment of World Car Free Day 2. The development of World Car Free Day

When many European cities are facing the increasingly serious air and noise pollution caused by automobiles, 1998, the French Green Party and the then French Minister of Land Consolidation and Environment, Mrs. Dominique Vanne, launched a campaign "I won't drive in the city today", which was echoed by the capital Paris and 34 other provinces and cities. 1On September 22nd, 1998, citizens of 35 cities in France voluntarily gave up their private cars, and designated this day as "Car Free City Day". On "Car Free Day", participating in the city will enhance people's awareness of environmental protection, understand the harm of air pollution, and encourage people to use cleaner means of transportation to further improve their quality of life, mainly by restricting motor vehicles from entering the city, setting up pedestrian areas, bicycle areas and holding other related activities. In February 2000, the European Commission and nine EU member states designated September 22nd as "Car Free Day". On September 22nd, 1999, more than 150 cities in France, Italy, Switzerland and other countries participated in the "Car Free Day" activity. In February 2000, the European Commission and nine EU member states designated September 22nd as "Car Free Day in Europe". Environmental protection activities aimed at improving urban air quality, reducing urban traffic pressure and changing urban traffic concepts.

Activities of World Car Free Day

Dominique Vane, the French Green Party and then Minister of Land Consolidation and Environment, put forward an activity "I won't drive in the city today", which was echoed by the capital Paris and 34 other provinces and cities. On September 22nd every year, some cities and towns implement car restrictions, and only public transport, pollution-free vehicles, bicycles and pedestrians are allowed to enter the city. This activity gave the city a short respite and soon swept across Europe.

Reasons for setting up World Car Free Day 3 What are the environmental pollution caused by driving?

1, automobile pollution mainly refers to automobile exhaust pollution. Of course, it also includes car noise pollution. Automobile exhaust contains S oxides, carbon dioxide and carbon monoxide generated by insufficient oxidation of hydrocarbons and oxygen. Sulfur oxides are the main cause of acid rain. The main harmful component of acid rain is sulfuric acid. Too much carbon dioxide will lead to the greenhouse effect. Carbon monoxide itself is a highly toxic gas, which can combine with hemoglobin and cause hypoxia and suffocation.

Automobile exhaust is not only harmful to people, but also toxic to plants. Secondary pollutants in waste gas, such as ozone and ethyl peroxynitrate, can cause necrotic spots and withered spots on plant leaves, and ethylene can affect the flowering and fruiting of plants. Automobile exhaust is more harmful to beets, spinach, tomatoes and tobacco, so the reduction of crop production on both sides of the road is inseparable from the pollution of automobile exhaust.

3. photochemical smog. Nitrogen oxides (nitrogen oxides) mainly refer to NO and NO2. NO and NO2 are both harmful gases to human body. Nitrogen oxides and hydrocarbons (HC) are exposed to strong ultraviolet rays from the sun in the atmospheric environment, resulting in a new secondary pollutant-photochemical smog. In this complicated photochemical reaction process, photochemical oxidants (mainly O3) and other complex compounds are mainly generated, which are collectively called photochemical smog.
