Rich nations should step-up support for poorer countries to go green, Japan says

Rich nations should boost financial and technical support to poorer countries to help them tackle climate change and achieve similar decarbonisation goals, a senior Japanese environment ministry official said ahead of a G7 summit in Hiroshima.

Developed countries promised in 2009 to transfer $100 billion annually between 2020 and 2025 to vulnerable states hit by increasingly severe climate-linked impacts and disasters - but that target was never met.

G7 energy and climate ministers discussed how to meet that goal when they met in the Japanese city of Sapporo last month.

Ono Hiroshi, vice-minister for global environmental affairs at Japan's environment ministry, said during an interview with Reuters that Japan has begun disbursing the $70 billion it committed in total financing over the 5-year period.

"All countries should follow the good example of Japan so that we could achieve the $100 billion goal," he said, adding that he hoped that the level would be achieved as soon as possible and maintained through 2025.

Developing countries say they need far more support than that from the rich nations, who are responsible for most of the greenhouse gas emissions, otherwise they cannot afford to cut CO2 emissions.

G7 climate and energy ministers have underscored the need to broaden the financing contributor base, but the commitment of providing annual financing of more than $100 billion after 2025 was subject to negotiations, Ono said.

Japan and other G7 members aim to reach net-zero greenhouse emissions by 2050 at the latest, by accelerating their transition to clean energy.

The G7 leaders are expected to reaffirm their climate goals during the summit in Hiroshima on May 19-21, Ono said, adding that he hopes they will also endorse other agreements reached at the ministerial meeting in Sapporo.
