If the vehicles have internal combustion engines burning fossil fuel, then, yes, they release carbon dioxide (CO2). So any vehicles running on petrol, petroleum, gasoline, diesel, aerogas, aviation fuel, kerosene, natural gas and others, even coal fired steam engines release CO2 (from before the time of the dinosaurs).

Renewable fuels for vehicles, like ethanol, biofuel, biodiesel, biogas and others also release carbon dioxide (removed from the atmosphere when the plants grew).

Electric vehicles release no CO2, but they might be responsible for CO2 emissions if their electricity comes from fossil fuels. Electric vehicles charged with electricity from renewable sources release no carbon dioxide.

Which processes increase the levels of carbon dioxide in the atmosphere?

Respiration: All animals breathe out carbon dioxide, but this is part of the carbon cycle.Volcanic Eruptions: These give off massive amounts of Carbon Dioxide, but humans add the same amount with three days of fossil fuel emissions.Combustion: Burning of fossil fuels (coal, oil and natural gas) in industry, transport and the generation of electricity, which releases carbon dioxide (CO2), is the main process increasing CO2 levels.

Carboniferous plus time scale plus 2010?

there is no word called carboniferous carbon is an element that has a grayish blackish color. its most common molecule is carbon dioxide. if you add that to the time scale, the carbon dioxide will add up in the atmosphere that we live in. ifyou add 2010 then you havethe amount of carbon dioxide in the atmosphere in the year 2010... which is alot. and people are tryingto reduce carbon emissions.


How do animals add carbon to the atmosphere?

Animals add carbon to the atmosphere through processes like respiration, decomposition of organic matter, and methane production. When animals breathe out, they release carbon dioxide into the air. Additionally, when animals die and decompose, carbon is released back into the atmosphere.


How are humans affecting carbon dioxide gas that is in the atmosphere?

We continue to add to it. Humans have been digging up and burning fossil fuels for 250 years. Burning this coal, oil and natural gas for industry, transport and to generate electricity has released billions of tons of extra carbon dioxide into the atmosphere. We have also cut down forests all over the world that used to remove carbon dioxide from the air.


What are some things that might add gases to the earth's atmosphere?

Burning of fossil fuels (coal, oil and natural gas) in industry, transport and the generation of electricity, which releases carbon dioxide (CO2).


Does logging really add CO2 to our atmosphere?

Yes. Trees are so important because they turn Carbon Dioxide from the atmosphere into Oxygen which we need to stay alive. So, the more trees that are cut down, the more Carbon Dioxide will stay in the atmosphere.


What human activities do not add carbon dioxide to the atmosphere?

Riding a bicycle is carbon neutral, which means it has no carbon footprint. It does not increase the amount of carbon dioxide in the air.Many other human activities, particularly sports and exercise are carbon neutral. But whenever you turn on some electrical gadget or ride in a fossil fueled vehicle you start increasing the carbon dioxide in the air.


Which process removes carbon dioxide from the atmosphere?

There are several. The main ones are:PhotosynthesisCarbonate formationDissolution of carbon dioxide into seawater
