The Kyoto Protocol, which the EU has recently ratified, calls for a quantitative reduction in greenhouse gas emissions by the year 2008 to 2010. However, global emissions, sources and sinks, are not yet accurately known. The new EU EVERGREEN project proposes to improve this situation by using the measurements of ENVISAT, a European Earth Observation satellite. Improved greenhouse gas emission inventories will be produced from a combination of measurements and (inverse) modeling. The feasibility and quality of the method will be assessed. Measurements include (partial) columns of various trace gases. The focus is on methane and carbon monoxide, and on regional and seasonal variations. The concentrations of trace gases measured by SCIAMACHY and MIPAS will be retrieved and validated. The use of measured trace gas distributions, rather than emissions, is expected to produce more accurate radiative forcing calculations. Carbon dioxide source and sink strengths will be included on a best-effort basis. End user involvement in the project is arranged through the participation of one coal industry and several national/ European institutes, with responsibility for environment and climate issues. Limitations and requirements for a space-borne Global Climate Observing System for top-down emission inventory assessments will be established.
