Biomass Energy in Pennsylvania: Implications for Air Quality,
Carbon Emissions, and Forests

Although often considered “carbon neutral,” biomass facilities emit more carbon dioxide (CO2)
per unit of energy generated than fossil fuel facilities, generating a “carbon debt.”
The American Lung Association “does not support biomass combustion for electricity
production” and “strongly opposes the combustion of wood and other biomass sources at
schools and institutions with vulnerable populations.” The Massachusetts Medical Society
opposes construction of large-scale biomass energy plants, stating that they pose an
“unacceptable risk to the public’s health.”

Despite its frequent portrayal as “clean,” biomass combustion is a major source of particulate matter,
making it of concern from a public health perspective. The effects of particulate pollution on respiratory
and cardiac health are well documented and are characterized by a linear response that extends below
the current EPA health threshold.

Some interesting comparisons emerged such as 1 kg of fast and slow wood burning produces nearly the same number of particles as for each km driven by a heavy duty vehicle (HDV) and a light duty vehicle, respectively.
