A United Nations evaluation panel narrowed to three April 23 the number of groups vying to host the U.N. Climate Technology Center for boosting clean energy technologies. The top proposals include a consortium led by the U.N. Environment Program that includes the U.S. National Renewable Energy Laboratory; the Global Environment Facility, which provides environmental grants to developing countries; and Det Norske Veritas AS. The three proposals were selected from among nine submitted in March. The center was formally launched at last year’s U.N. climate talks; final selection will be made at this year’s in Doha, Qatar.
