The government of Japan is to review in 2021 its mid-term goal of reducing greenhouse gas emissions 26 percent by fiscal 2030, from fiscal 2013 levels.
It plans to accelerate efforts to achieve carbon neutrality in 2050, by studying necessary measures and laying out a concrete roadmap.
Government officials hope to come up with a higher number by this autumn and submit it to the United Nations, along with specific measures. They hope to announce a new goal at the COP 26 world conference on climate change scheduled for November in Britain.
A number of countries have announced a goal of net zero CO2 emissions by 2050 and mid-term goals set for 2030 are being reviewed.
Britain announced in December that it is resetting the target to at least 68 percent reduction in emissions by 2030, from 1990 levels.
The European Union also raised its target to 55 percent reduction by 2030, against 1990 levels.
