With an aim to facilitate the achievement of goals from the landmark 2015 Paris agreement, the Japan Action Climate Summit, organized by nonstate actors, was held Friday in Tokyo's Minato Ward.

A total of 257 organizations and municipalities took part in the meeting to share their knowledge and incentives for tackling climate change.

"Today is a historic day in Japan's fight against climate change. Japanese nonstate actors have stood together in support of the Paris agreement," Takejiro Sueyoshi, a special adviser to the U.N. Environment Program Finance Initiative, said at the start of the meeting.
