U.N. climate report seeks clearer economics to guide action

By Alister Doyle, Environment Correspondent BERLIN (Reuters) - A U.N. report about ways to fix global warming due on Sunday is likely to disappoint investors seeking clear-cut economic calculations about the benefits and costs of curbing rising greenhouse gas emissions. The United States and other governments, at talks in Berlin, were pushing for clearer economic arguments from the Intergovernmental Panel on Climate Change (IPCC), which is meant to guide trillion-dollar curbs on greenhouse gas emissions. Switzerland said the "central question" for policymakers was to compare costs and benefits of different levels of action to rein in greenhouse gases, something which does not appear in the draft. "We provide much more economic analysis this time, but we are not putting that forward as the only impact," Rajendra Pachauri, chair or the IPCC, told Reuters.
