TOKYO -- Japan unveiled a plan Friday to achieve its goal of net-zero greenhouse gas emissions by 2050 that calls for tripling renewables' share of power generation to at least 50%.

The government estimates that its "green growth strategy" will generate 190 trillion yen ($1.83 trillion) in economic effects that year. The road map lists challenges and solutions in 14 key fields, including hydrogen and offshore wind. It calls for average net emissions of zero from new building and home construction by 2030 and for ending all sales of new gasoline-only vehicles by the middle of that decade.
