Frequently Asked Questions
Straight answers to the most common questions about the biomass industry.
Is biomass energy carbon neutral?
In the short term, no. Burning wood releases more CO2 per unit of energy than coal. While trees can regrow and re-absorb that carbon, this process takes decades to a century. During that critical window, the added CO2 warms the planet.
Is biomass better than coal?
From a pure carbon emissions standpoint at the smokestack, biomass emits more CO2 than coal. However, it emits less sulfur and mercury. The primary argument for biomass is that it is "renewable," but climate scientists argue that "renewable" does not mean "carbon-free" or "climate-friendly" within relevant timeframes.
Do wood pellets come from waste?
Industry groups often claim pellets are made from sawdust and mill residues. However, investigations have repeatedly shown that whole trees and large roundwood are used to meet the massive demand for exports, as there is simply not enough waste wood available.
Why do governments subsidize biomass?
Subsidies are often based on older policy decisions that classified all biomass as automatically carbon neutral. These policies were designed to support forestry industries and reduce dependence on fossil fuels, but they often fail to account for the latest climate science regarding carbon debt.
How does biomass affect local health?
Biomass plants release fine particulate matter (PM2.5), nitrogen oxides (NOx), and volatile organic compounds (VOCs). These pollutants are linked to asthma, heart disease, and respiratory issues, disproportionately affecting communities near the plants.
