What produces most carbon dioxide?

Answer 1

• China and India

Answer 2

Trees and other growing vegetation remove the most carbon dioxide from the atmosphere.

Answer 3

Vegetation releases CO2 in the fall and winter, but takes up carbon again in the spring and summer. In the 800,000 years preceding the industrial revolution, atmospheric CO2 varied from 250 to 280 ppm. It is pretty clear the short term contribution from natural sources must be quite small, overall.

Humans emit 100 times the CO2, via fossil fuel consumption, as do all earth's volcanic emissions combined. We are responsible for over 30 billion tons of CO2 each year.

Cement manufacture is the second largest source of CO2, at about 5% per year. We release more than 5 times as much CO2 just from curing concrete than is emitted by all earth's volcanoes combined.

Answer 4

The largest source of carbon dioxide (CO2) emissions are currently from electric generation through the combustion of fossil fuels. Particularly the burning of coal is most pollutive, as compared to oil or natural gas generation.

Answer 5

Nature produces over 90% of all CO2.

Heating, cooling and powering our homes and buildings makes up over half of the CO2 man produces. Automobiles produce about 33% of our CO2 contribution.

In total man contributes 3 to 6% of the total CO2.

Answer 6

About one day of coal fired power plants makes more co2 then all other sources do in about a years time. Solutions are available. and using less power will not stop them from burning coal . These things burn the same amounts 24/7 no matter what the current peak demand is.

My solutions are most simple. 1st burn the people getting rich from coal in the power plants for some cheap electricity. 2nd geo thermal mandatory. 3rd solar power and wind replace all power plants. 4. more trains to move cargo and commuters via park and ride applications. 5. public electric bikes available every where.

And why do we need to cut so much grass??? along the free ways let the trees come back. Any area not being used for say a field sport should be overgrown by trees. this would be a huge co2 sink.

Also we could build underground. and let nature grow above the ground. that would be nice.

Very easy to do. but the fossil fuel industry would lose a little to help our planet heal.

Answer 7

Coal is the fossil fuel that releases the most carbon when burnt.
