What percentage of carbon dioxide is caused by car fumes?

Answer 1

AnswerYes, they do. When a hydrocarbon (e.g: gasoline) is burned, it releases water, carbon dioxide, and energy.

For each litre of petrol used, the CO2 produced from the exhaust is about 2.5 kg. A typical annual use of 1200 litres of petrol produces about 3 tons of CO2.

Cars produce almost 1% of all CO2. Nature, through rotting vegetation, produces 95%. However, vegetation absorbs an equal mass of CO2 out of the atmosphere while growing. Cars do not do that.
Yes, cars do produce carbon Di-oxide.. U.S. Environmental Protection Agency (EPA) originally viewed carbon dioxide as a product of "perfect" combustion, but now views CO2 as a pollution concern. Carbon dioxide is a greenhouse gas that traps the earth's heat and contributes to Climate Change.

Answer 2

Yes Carbon dioxide as well as carbon monoxide are present in car exhaust. Carbon dioxide if of less concern the carbon monoxide. A catalytic converter is used to reduce the amount of these chemicals and is a device used to reduce the toxicity of emissions from an internal combustion engine. First widely introduced on series-production automobiles in the U.S. market for the 1975 model year to comply with tightening EPAregulations on auto exhaust, catalytic converters are still most commonly used in motor vehicle exhaust systems.

Answer 3

It is estimated that around 15-20% of global carbon dioxide emissions are caused by car fumes. This includes emissions from both passenger vehicles and other forms of transportation such as trucks and buses.

Answer 4

Yes. Cars burn hydrocarbon fuel, which produces carbon dioxide, carbon monoxide, and water vapor.

Answer 5

Light vehicles, such as cars, produce around 30 percent of the carbon dioxide being released in the United States. Each gallon of gas burned produces 24 pounds of carbon dioxide.

Answer 6

Yes, carbon dioxide and water mostly. Some carbon monoxide too, usually.

Answer 7

Carbon dioxide (CO2).
