How many acres of forestland does it take to offset the carbon dioxide emissions from medium-sized coal-fired power plant?
Roughly speaking, about 220,000 acres would be required to offset emissions from a average size power plant. This assumes an average coal power plant from the existing fleet and a forest uptake rate of 3 tons of carbon per acre per year (Newel and Stavins, Journal of Environmental Economics and Management 40, 211-235, 2000. Figure 1 without discounting).
