TOKYO -- Japan promised a steeply higher emissions reduction goal at Thursday's U.S.-led climate summit, but achieving it will require drastic steps such as ditching coal-fired power plants and replacing the nation's car fleet with zero-emission models.
The new goal is to cut greenhouse gas emissions by 46% from fiscal 2013 levels by fiscal 2030. The biggest hurdle is decarbonizing the energy sector, which generated about 40% of Japan's carbon dioxide emissions in fiscal 2019.
