According to other Wikipedia answers, breathing by humans produces approximately 2.3 pounds (1 kg) of carbon dioxide per day per person.
If there are approximately 6.8 billion humans on the earth, collectively they would emit 6.8 billion kg per day, or 6.8 million metric tons per day. In a 365 day year, humans would produce 2.482 billion tons from breathing.
The Energy Information Administration of the US government said in their May 27, 2009 International Energy Outlook 2009 that world carbon dioxide emissions were 29.0 billion metric tons in 2006.
Human breathing would then be contributing approximately 8.5% of all CO2 emissions.
It is important to remember that breathing is carbon-neutral, that is, we take in carbon when we eat and drink, and this same carbon is emitted when we breathe. So breathing does not add extra carbon dioxide to the atmosphere.

Do humans emit carbon dioxide?
Yes,I think we breath it out and plants get it and they give us oxegen which we breath and than emit carbon dioxide
Why is biomass like fossil fuels?
They are both burned to release energy. They both emit carbon dioxide when burnt. However fossil fuel releases 300-million-year-old carbon dioxide, so it adds to global warming. Biomass releases carbon dioxide that was removed from the atmosphere when the plants grew, so it is part of the carbon cycle, NOT contributing to global warming.
What gas does a plant emit?
We release carbon dioxide for them to breath and they release oxygen to help us breathe and that's why without plants the world would be empty plants would have died because we would of died , pets will of died as they wouldn't have us. Animals in the wild etc.
Why do most plants and animals need oxygen to survive?
Although plants to use oxygen, they emit unneeded oxygen into the atmosphere. This helps to replenish oxygen supplies for other organisms.
What is the process in which plants use light energy to synthesize food sugars from carbon dioxide called?
Photosynthesis is the process at which plants convert Carbon Dioxide (CO2- one part carbon 2 parts oxygen) into organic compounds or sugars that help the plant survive. As a result they emit clean Oxygen or O2 which is vital for our being. That is why we need to do our best to preserve, protect, and plant trees and other plants. (That is my "3 P's.")
What gasses are you emitting?
Humans emit carbon dioxide by breathing. They also emit carbon dioxide by belching and they emit methane by farting.
Does Soils emit carbon dioxide into the atmosphere?
Yes, I think soil can emit carbon dioxide into the atmosphere.
Do seeds emit carbon dioxide?
no
How is carbon dioxide alive?
Its not. Carbon Dioxide is a gas that trees and plants ingest and we emit.
Are animals primary consumers of carbon dioxide?
Animals emit carbon dioxide. Plants consume carbon dioxide.
Do humans emit carbon dioxide?
Yes,I think we breath it out and plants get it and they give us oxegen which we breath and than emit carbon dioxide
Do cars pollute the air or people?
Both. Cars emit Hydrocarbons + Nitrogen Oxides + Carbon Dioxide + Carbon Monoxide. People emit Methane and Carbon Dioxide.
How much carbon dioxide does a Lorry emit?
500g
What are the two main gases in a volcanoes emit?
Steam, Sulfur dioxide, Carbon Dioxide.
Does Money plant emit carbon dioxide during night?
no
How much carbon dioxide does each light bulb emit?
None. Light bulbs do not emit carbon dioxide. The electricity used to power the light bulb may have been produced by a method which emits carbon dioxide (then again, it may not have), but the bulb itself doesn't emit anything except heat and light.
Wave length of carbon dioxide laser?
The wavelength of carbon dioxide laser usually emit at a wavelength of 10.6 μm.
