Carbon Cycle Implications of Forest Biomass Energy Production in the Northeastern United States

摘要: There has been enormous interest in the use of forest biomass as a component renewable energy portfolio northeastern United States. While often touted an inherently “carbon-neutral” source, it become clear that wide range factors need to be considered evaluate net carbon and climate impact production (Cook Beyea 2000; Abbas et al. 2011; Schulze 2012; Zanchi 2012). Net growth forests currently provides important offset fossil fuel emissions greenhouse gases, but most studies predict sequestration rates both regionally nationwide will decline over next 20–50 years (Hurtt 2002; USDA Forest Service The magnitude annual US is believed product three main factors: stabilizing or even reversal century-long trend increasing forestland base due reforestation abandoned farmland (Drummond Loveland 2010), declining at stand level because maturation 2002), harvest (Radeloff 2006). All these raise questions about sustainable supply feedstocks from (Buchholz 2011) well future regional stocks under new demand for energy.
