Emissions of climate-changing greenhouse gases (GHG) from the EU-25 increased by 18 million tonnes (0.4 %) between 2003 and 2004. "The 0.4 % increase is comparable to the amount of CO2 emissions released by 3 million people if they were to drive their cars around the earth," - Professor Jacqueline McGlade, executive director of the European Environment Agency (EEA).
