The data comes from national reports to UNFCCC. For developing countries (i. e. non-Annex I countries), data is either old or missing. To better reflect the truth, we chose to overlap 2000 data from IEA (dashed circles). Please note that the calculation methods are different. Data is for 2004, except * (1994) and dashed circles (2000). Only emissions above 40 million tonnes of CO2 equivalent are represented.
