Japan's Environment Minister Ito Shintaro has announced support measures for developing countries to help them reduce their greenhouse gas emissions.

Ito attended the ministerial meeting of the COP28 UN climate change conference in the United Arab Emirates on Saturday.

Prior to the meeting, Ito noted all countries must unite to address the climate crisis, but each country faces different challenges. He said Japan hopes to provide technological, economic and financial support to resolve the difficulties.

The minister told the meeting that Japan will help developing nations in Asia draw up emissions reduction targets by using data from a new greenhouse gas observation satellite it plans to launch next year.

He also announced a public-private partnership for the development of early warning systems mainly in the Asia-Pacific region. It aims to help developing nations deal with disasters related to climate change.

The announcement comes as some environmental groups have criticized Japan for not doing enough to address climate change.

Japan is the only member of the Group of Seven nations not participating in the Powering Past Coal Alliance, which aims for a transition from coal-fired power generation.
