Greenpeace activists wearing masks of world leaders hold a banner reading "Coal fired Arctic meltdown" and stand in front of the Svea Coal Mine, where they protested by blocking the conveyor belts and prevented Arctic coal from being exported to European coal fired power plants. Coal burning is the greatest threat to our climate, accounting for over 40% of all fossil fuel CO2 emissions, making it the largest single source.
