No, they release carbon and others from the exhaust but later the carbon goes through synthesis in which it forms carbon dioxide in the atmosphere.

How much automotive exhaust is produced by cars each year?

Vehicle exhaust is mostly carbon dioxide, with a little water, carbon monoxide, hydrocarbons, and nitrogen oxides. This answer deals with the carbon dioxide content only.Sixteen percent (16%) of human carbon dioxide greenhouse gas emissions comes from road transport (cars, trucks and buses). Cars are responsible for about half of this (8%).Humans are responsible for around 35 billion tonnes of carbon dioxide emissions every year.Car emissions, 8% of that total, is around 2.8 billion tonnes of carbon dioxide (2,800,000,000).


What is Carbon dioxide released into the atmosphere by?

Many things contribute to Carbon dioxide being released. Cars, animals, burning fossil fuels, etc.


What Accounts for most of the carbon dioxide emissions for a country?

The burning of fossil fuels for energy production is the primary source of carbon dioxide emissions for a country. This includes emissions from transportation, electricity generation, industrial processes, and heating. Deforestation and land-use changes also contribute to carbon dioxide emissions.


Why there is increase in carbon dioxide gas?

More living things such as humans are being brought into existence, breathing out more carbon dioxide. Factories, cars and planes also contribute to rising carbon dioxide and carbon monoxide in the atmosphere from the smoke they release. Plants such as trees are supposed to convert the carbon dioxide into oxygen, but we keep cutting them down. In short - because of the human race.


What gas is produced by respiration?

Carbon dioxide is produced as a byproduct of cellular respiration in organisms, including humans and animals. During respiration, glucose is broken down in the presence of oxygen to produce energy, water, and carbon dioxide.

Which produces more carbon dioxide cars or homes?

Cars produce more carbon dioxide than homes on average. The transportation sector, which includes cars, trucks, and airplanes, is one of the largest sources of carbon dioxide emissions worldwide. Homes also contribute to carbon dioxide emissions through energy consumption for heating, cooling, and electricity, but their impact is generally lower compared to cars.

Carbon dioxide (CO2).


How do cars emit carbon dioxide?

Cars run on burning of fossil fuel, which is mainly hydrocarbons, compound of carbon and hydrogen which on oxidation (burning) produces Carbon dioxide, water (and Carbon Monoxide if oxygen is not sufficient for combustion).
