The historical emissions for Annex I countries are provided from 1990 onwards using the UNFCCC National Inventory Submissions, Common Reporting Format Tables (CRF).
All emissions relevant under the Kyoto Protocol (Annex A) are considered with exception of emissions from land use, land-use change and forestry (LULUCF). These LULUCF emissions are analyzed separately.
For the developing countries we analyze, we determine the best data sources for historical levels on a case by case basis. Detailed data source information is in each case provided on the country pages. Pledges are considered including LULUCF emissions.
