The ETP BLUE Map Scenario assumes that global energy-related carbon dioxide (CO2) emissions are reduced to half their current levels by 2050. This scenario examines ways in which the introduction of existing and new low-carbon technologies might achieve this at least cost, while also bringing energy security benefits in terms of reduced dependence on oil and gas, and health benefits as air pollutant emissions are reduced.
The BLUE Map Scenario is consistent with a long-term global rise in temperature of 2°C to 3°C, but only if the reduction in energy-related CO2 emissions is combined with deep cuts in other greenhouse-gas (GHG) emissions. The Baseline Scenario considers the business-as-usual case, not reducing emission levels to any predetermined goal by 2050. The BLUE Map and Baseline Scenarios are based on the same macroeconomic assumptions.
