Burning wood instead of coal therefore creates a carbon debt — an immediate increase in atmospheric CO2 compared to fossil energy — that can be repaid over time only as — and if — NPP [net primary production] rises above the flux of carbon from biomass and soils to the atmosphere on the harvested lands.»

The American Lung Association does not support biomass combustion for electricity production, a category that includes wood, wood products, agricultural residues or forest wastes, and potentially highly toxic feedstocks, such as construction and demolition waste.

The American Lung Association calls for effective enforcement of existing laws and regulations governing the combustion of wood and other biomass sources, as well as the expanded regulation of air pollution emissions from these sources.

But the results from projects like the Nyabyeya biomass energy plant are renewing interest in wood and biomass as larger scale energy sources, and an alternative to fossil fuels.

Another category is biomass grown in excess of what would have grown absent the demand for bioenergy, such as growing winter cover crops for energy and replacing traditional — yet inefficient — fuel wood harvests in some poor countries with wood grown in agroforestry systems and local plantations.

Burning biomass, whether directly as wood or in the form of ethanol or biodiesel, emits carbon dioxide, just like burning fossil fuels.
