The historical emissions for Annex I countries are provided from 1990 onwards using the UNFCCC National Inventory Submissions, Common Reporting Format Tables (CRF). These data are currently reported in accordance with the IPCC 1996 guidelines.
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 analysed separately.
For developing countries, we determine the best data sources1 for historical levels on a case by case basis. In each case, we provide detailed data source information on the country pages. We consider historical emissions excluding LULUCF except for countries that formulate their pledge explicitly taking into account emissions from this sector (e.g. Brazil and Indonesia).
