The United States Department of Agriculture (USDA) has generated new projections of world roundwood and forest product demand using the Forest Resource Outlook Model (FOROM). The projections are made for four scenarios of global climatic warming and economic growth – (1) lower warming, moderate growth; (2) high warming, low growth; (3) high warming, moderate growth; and (4) high warming, high growth – based on the Intergovernmental Panel on Climate Change’s four “shared socioeconomic pathways” scenarios, which assume differing climate policies.
