The European Commission, DG XII, has recently published a report under the Environment and Climate programme entitled the "Quantification of West European methane emissions budget by atmospheric measurements".

Methane is a particularly important greenhouse gas, as it has a high global warming potential and because of the elevated level of current atmospheric methane concentrations and future trends. The aim of the project was to quantify methane emissions in Western Europe by measuring atmospheric methane concentrations. Part of the project dealt with measurement of isotope ratios, to obtain information on the nature of the sources, thus enabling an independent check on existing methane inventory data (CORINAIR 90).

The project involved four expert research groups from four EU countries: the United Kingdom, Germany, Ireland and The Netherlands. The results of the project show that there is an urgent need to improve European methane inventory data, with a view to providing a sound basis for different political options and decision-making procedures. The report also highlighted the need for accurate global monitoring and the use of inverse modelling techniques to quantify methane sources, a basic element in the development of cost-effective greenhouse gas reduction strategies.
