Data are from the Reference Scenario for four major types of energy development: coal production, biomass burning for electricity, biofuel production, and wind power. Energy development is partitioned among habitat types, as depicted in Figure 2. Numbers in parentheses are the change in value under the Core Cap-and-Trade Scenario. For example, boreal forests have 94 km2 affected under the Reference Scenario by coal, but have 27 fewer km2 affected by coal under the Core Cap-and-Trade Scenario (i.e., 67 km2).
