5. Can biomass contribute to reducing greenhouse gas emissions?

Biomass has the potential to significantly reduce greenhouse gas emissions compared to fossil fuels. When biomass is burned or converted into biofuels, it releases carbon dioxide (CO2) into the atmosphere. However, the carbon emitted is part of the natural carbon cycle, as plants absorb CO2 during their growth. The net emissions from biomass can be considered carbon-neutral or even carbon-negative if sustainable practices are followed, such as replanting harvested trees.

  • Expert response: Biomass can play an important role in mitigating climate change by displacing fossil fuel consumption and reducing overall carbon dioxide emissions.
