June 2 (Reuters) - Following is a comparison of cuts in greenhouse gases by leading democracies in the Group of Seven, whose leaders will meet in Brussels this week, after the United States announced sweeping plans to reduce power plant emissions on Monday. Official data show that the United States has performed better in restricting emissions since 1990 than Canada and Japan but lags Italy, France, Germany and Britain. G7 leaders will met in Brussels on June 4 and 5. The proposed U.S. emissions cuts from existing power plants, of 30 percent below 2005 levels by 2030, are the centrepiece of President Barack Obama's policy to fight climate change. The existing U.S. national goal, set in 2009, is to cut emissions by 17 percent below 2005 levels by 2020, equivalent to a cut of 3.5 percent below levels in 1990 - the U.N. benchmark year - after a sharp rise in emissions in the 1990s. Obama's goal for the power sector stretches to 2030 - so far no G7 nations have set firm nationwide targets so far ahead. The European Union is considering national cuts of 40 percent below 1990 levels by 2030 but is not expected to reach an outline agreement before October this year at the earliest.

The EU-wide Emissions Trading System covers around half or Europe's greenhouse gas output and caps the emissions of over 13,000 power plants, factories and airlines that by 2020 are due to be 21 percent below 2005 levels, when the market began. For the sectors outside the ETS, such as agriculture and land transport, EU nations share a target to cut emissions 10 percent under 2005 levels by 2020, which varies based on each countries' relative wealth. France and Germany are required to cut emissions by 14 percent, for instance. (Reporting By Alister Doyle in Oslo, Ben Garside in London and Barbara Lewis in Brussels, editing by David Evans)
