Demand Seen Thin in First US Greenhouse Auction
US Northeast power companies likely will not race to buy permits to emit the main greenhouse gas in the country's first carbon auction later this month because the region's emissions of the gas have slipped over the last few years, experts said. The Regional Greenhouse Gas Initiative, a group of 10 states in the US Northeast that formed the first US greenhouse market, will regulate carbon dioxide emissions from power plants starting next year. It will hold its first auction for permits to pollute more than 12 million tons of emissions on Sept. 25.
