Carbon allowances in the European Union’s emissions-trading system, the world’s largest, dropped along with natural gas and German electricity prices.
EU permits for December fell as much as 1.1 percent to 14.33 euros ($18.36) a metric ton. They were at 14.34 euros as of 9 a.m. on London’s European Climate Exchange, trading above their 30-day moving average of 14.27 euros.
U.K. natural gas for delivery next month lost as much as 1.9 percent to 39 pence a therm, the lowest intraday level since July 21, according to broker prices compiled by Bloomberg. Lower business gas prices may prompt some power generators to switch to the fuel, which requires about half as many carbon permits to burn as coal.
German baseload power for next month dropped 0.8 percent to 47.95 euros a megawatt-hour, according to broker prices compiled by Bloomberg. Lower prices can reduce the incentive to sell electricity forward, curbing demand for emission permits.
