Germany's greenhouse gas emissions fell in 2017, largely thanks to the closure of coal-fired power plants, but automakers and factories still need to do more to cut pollution, government officials said. Overall emissions in Europe's biggest economy fell 0.5 percent through the year, according to preliminary data released by a federal environment agency."While energy-related emissions fell significantly, those in transport and the manufacturing industry went up," the Umweltbundesamt (UBA) said in a statement."Therefore, additional measures are necessary to set Germany on a course toward its targets again."The energy industry, which is undergoing a staged transition to renewable technologies, saw its emissions fall by 4.1 percent, or 13.7 million tons, in 2017, the UBA said.
