Embattled miner and commodities trader Glencore Plc on Wednesday called on delegates meeting for a global climate summit later this year to adopt a policy that recognizes coal as an important energy source. “We need global policy that acknowledges the global energy reality that fossil fuels including coal will continue to be used,” Glencore head of global coal assets Peter Freyberg said in prepared remarks for a speech in Australia. “We also need a policy which addresses the funding gap to facilitate the build of high-efficiency, low emission power stations,” Freyberg said.
