Apes Renewable Energy

How does biomass reduce our carbon footprint by producing less CO2 than fossil fuels?

• Plants absorb the same amount of CO2 that is released when it is burned.

• Plants remove CO2 from the atmosphere and put it permanently into the ground.

• Biomass filters CO2 to make it more environmentally stable.

• Biomass doesn't release any CO2 when burned.
