Data sources
- Country-level CO2 emissions from fossil fuels from Global, Regional, and National Fossil Fuel CO2 Emissions. Carbon Dioxide Information Analysis Center (CDIAC), Oak Ridge National Laboratory, U.S. Department of Energy.
- CO2 emissions from changes in land use from Carbon Flux to the Atmosphere from Land-Use Changes 1850-2005 Carbon Dioxide Information Analysis Center (CDIAC), Oak Ridge National Laboratory, U.S. Department of Energy.
- GDP and population from Statistics on World Population, GDP and Per Capita GDP, 1-2006 AD Conference Board and Groningen Growth and Development Centre, Total Economy Database.
- Business As Usual CO2 emissions projections are calibrated to the scenarios in the IPCC SRES scenarios 's Special Report on Emissions Scenarios (SRES), with the International Energy Agency (IEA)’s World Energy Outlook 2007 allocations between regions. The C-LEARN default BAU scenario is the IPCC's A1F1 scenario. For an overview of the IPCC scenarios, see "What is the range of GHG emissions in the SRES scenarios and how do they relate to driving forces?" in Summary for Policy Makers section of the SRES.
- Population and GDP projections are based on the United Nations’ World Population Prospects 2004 forecast and IEA’s World U.S. Energy Information Agency (EIA)'s International Energy Outlook 2008 GDP forecast, respectively.
