摘要: Exports of pellets from the United States (US) are growing significantly to meet demand for renewable energy in European Union. This transatlantic trade has raised questions about greenhouse gas (GHG) intensity these and their effects on conventional forest product markets US. paper examines GHG exported US using either biomass only or agricultural combined. We develop an integrated dynamic, price-endogenous, partial equilibrium model forestry, agricultural, transportation sectors investigate not direct life-cycle but also accompanying indirect market land use induced by changes prices products over 2007–2032 period. Across different scenarios high low pellet that can be met with biomass, we find based electricity is 74% 85% lower than coal-based electricity. produced 28% 34% only. due carbon stock caused harvest rotations, wood production account 11% 26% overall only; negative biomass.
