No, biomass burns grown vegetation to produce energy. Because the vegetation grew recently, it means it took carbon out of the atmosphere recently. Burning it puts the same carbon dioxide back into the atmosphere. This makes it carbon neutral.

∙ 12y agoNo, burning biomass does not contribute to global warming.
Biomass (burning of plant material) does add carbon dioxide (CO2) to the atmosphere, but it is CO2 that was recently taken out of the atmosphere (when the plants were growing) so this is not extra CO2. Burning biomass then is part of the natural carbon cycle which moves CO2 in and out of the atmosphere.
The carbon dioxide that comes from burning fossil fuels (coal, oil and natural gas) was taken out of the atmosphere millions of years ago, so releasing it now is adding extra CO2 (and causing global warming).
This is why biomass is renewable energy and much better than fossil fuels.

∙ 9y agoNo. Biofuel is carbon neutral, that is, it removes carbon dioxide from the atmosphere when the plants are growing, and then releases the same greenhouse gas when the biofuel is burnt.

Does a refrigerator contribute to global warming?
Yes it does contribute to global warming beacause of the coldness in it
How does Mexico contribute to global warming?
Mexico does contribute to global warming. It does release greenhouse gases.
How do power stations contribute to global warming?
Power stations do contribute to global warming, as the more electricity we use the more global warming will develop to the earth. And gradual the earth will be destroyed because of us humans.
How do rice paddies contribute to global warming?
yes
Do sheep burps contribute to global warming?
Yes they do believe it or not
Does a refrigerator contribute to global warming?
Yes it does contribute to global warming beacause of the coldness in it
How does Mexico contribute to global warming?
Mexico does contribute to global warming. It does release greenhouse gases.
Which myth do scientists think contributes to global warming the most?
A myth is an incorrect belief. No myths contribute to global warming.A myth is an incorrect belief. No myths contribute to global warming.
Which continent does not contribute to global warming?
Antarctica makes hardly any contribution to global warming.
How do power stations contribute to global warming?
Power stations do contribute to global warming, as the more electricity we use the more global warming will develop to the earth. And gradual the earth will be destroyed because of us humans.
Does nuclear waste contribute to global warming?
No
Does humidity contribute to global warming?
Humidity does contribute to global warming, because water vapor is also a greenhouse gas, just as carbon dioxide it.
How do firework displays cause global warming?
They don't cause global warming, but they contribute in a small way towards it.
How do rice paddies contribute to global warming?
yes
What are facts about hydroelectricity?
Hydroelectricity does not contribute to global warming.
Why doesn't the complete combustion of ethanol from sugercane contribute to global warming?
Ethanol from sugar cane is a biofuel. Burning biomass or biofuel does not contribute to global warming. When the sugar cane was recently growing it removed carbon dioxide from the air. When the ethanol is burnt, that same carbon dioxide is returned to the air. This is part of the natural carbon cycle.The carbon dioxide that comes from burning fossil fuels (coal, oil and natural gas) was taken out of the atmosphere millions of years ago, so releasing it now is adding extra CO2 (and causing global warming).This is why biomass is renewable energy and better than fossil fuels.
How does ethanol reduce global warming?
Ethanol from plant material is a biofuel. Burning biomass or biofuel does not contribute to global warming. When the plant was growing it removed carbon dioxide from the air. When the ethanol is burnt, that same carbon dioxide is returned to the air. This is part of the natural carbon cycle.The carbon dioxide that comes from burning fossil fuels (coal, oil and natural gas) was taken out of the atmosphere millions of years ago, so releasing it now is adding extra CO2 (and causing global warming).This is why ethanol is counted as renewable energy and better than fossil fuels.
