			 Speaking at a coal summit on the sidelines of a U.N. climate 
			conference in Warsaw, Christiana Figueres said the coal industry 
			needs to change radically to help reduce the carbon emissions that 
			scientists say are warming the planet. 
 			"The world is rising to meet the climate challenge as risks of 
			inaction mount, and it is in your best interest to make coal part of 
			the solution," Figueres said.
 			The coal event was seen as a provocation by climate activists, who 
			used a crane to reach the ministry's roof, where they unfurled 
			banners criticizing Poland's — and the world's — reliance on coal 
			and other fossil fuels. Police used another crane to take them down, 
			as panelists at the coal summit said that the people in the room, 
			not the people on the roof, have the possibility to change the coal 
			industry.
 			Coal industry officials at the event didn't directly address her 
			remarks but said the world cannot do without coal because in many 
			countries it's the only available energy source. 			
 
 			"A major aim of the summit has been to encourage open and 
			constructive dialogue on the climate challenge — we're not going to 
			meet our climate objectives if we are not all part of the solution," 
			the World Coal Association, which organized the event, said in a 
			statement.
 			Polish Economy Minister Janusz Piechocinski, whose country generates 
			about 90 percent of its electricity from coal, said: "You cannot 
			have a low-emissions energy transformation without talking about 
			coal."
 			Coal accounts for less than 30 percent of the world's energy supply 
			but more than 40 percent of energy emissions, according to the 
			International Energy Agency.
 			Figueres, who was criticized by some climate activists for attending 
			the conference, noted coal's role in economic development since the 
			industrial revolution but said it's come at "an unacceptably high 
			cost to human and environmental health."
 			She said aging, high-polluting coal plants must be closed and new 
			plants should implement technologies that allow for emissions to be 
			trapped before they are released into the atmosphere. Such 
			technologies are expensive and currently not widely used.

			To bring down CO2 emissions to levels that would avoid dangerous 
			levels of warming, most of the existing coal reserves must be left 
			in the ground, Figueres said.
 			"Some major oil, gas and energy technology companies are already 
			investing in renewables, and I urge those of you who have not yet 
			started to join them," Figueres said.
 			Back at the U.N. conference later Monday, she told reporters she 
			didn't expect any major shift in the industry's deployment of 
			capital anytime soon.
 			"They really need to do a major, major rethink," Figueres said. "So 
			I don't expect them to stand up immediately and go, 'We are ready 
			for the challenge right now,' but I do expect them to take the 
			message very seriously."
 			That message was echoed by U.S. climate envoy Todd Stern.
 			"The world runs significantly on fossil fuels right now and that's 
			not going to change overnight," he said. "But at the same time if 
			we're going to get a grip on climate change ... the balance of 
			energy in countries all over the world is going to have to tilt much 
			more toward non-fossil sources."
 			Coal emissions have declined in the U.S. as some power plants have 
			switched to lower-priced natural gas. But they are growing fast in 
			China and India to meet the energy needs of their fast-growing 
			economies.
 			Coal industry officials say significant emissions reductions can be 
			achieved by improving the efficiency of coal-fired plants. But in 
			the long term analysts say expensive carbon-capture technologies 
			need to be implemented to make the deep cuts required to slow 
			climate change.
