Does biofuel contribute to global warming?

Answer 1

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.

Answer 2

No, 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.

Answer 3

They don't. Burning biomass wood chips does not contribute to global warming, if the wood is recently grown.

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 trees or 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.

Answer 4

Bio-fuels can require the clearing of forests in order to increase agricultural land for its production. Clearing of forests results in the release of greenhouse gasses.

Answer 5

No. 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.
