During the past four years, the study examined 80 forest types in 19 eco-regions in Oregon, Washington and California. If included both public and private lands and Private lands and different forest management approaches. “Most people assume that wood bioenergy will be carbon-neutral, however, our research showed that the emissions from these activities proved to be more than the saving. “The only exception to this, the researchers said, was if forests in hight fire-risk zones become weakened, as well as setting the stage for major fires. It’s possible some thinning for bioenergy production might result in lower emissions in such cases if several criteria are met, they said.
