U.S. climate envoy John Kerry arrived in Tokyo on Tuesday — just two months before a key U.N. summit — for talks with Japanese leaders on their decarbonization efforts at home and the fight against climate change on the international stage.

Kerry’s stop in Tokyo, as well as another in China’s Tianjin later in the week, is part of a larger worldwide effort by the U.S. to push other nations to adopt strong decarbonization targets at the U.N. meeting in Glasgow, Scotland.

The purpose of his visit was “to engage with international counterparts on efforts to address the climate crisis,” the U.S. State Department said in a statement.
