Energy and Climate in Japan
The Seventh Basic Energy Plan, the GX Promotion Act, and a mandatory emissions trading system from FY2026 have made Japan’s energy transition a policy market as much as a commercial one.
How Energy and climate policy is made in Japan.
Japan’s energy policy is set through the Basic Energy Plan, revised roughly every three years and last adopted in February 2025, and executed through METI’s Agency for Natural Resources and Energy and its advisory councils. The Seventh Plan restores nuclear to the mix, sets renewable targets for 2040, and underwrites hydrogen and ammonia through contracts for difference.
The GX Promotion Act layers a carbon price on top: a mandatory emissions trading system for large emitters from FY2026, a fossil-fuel levy from FY2028, and GX Economy Transition Bonds funding the investment framework in between. The rules for allocation, benchmarks, and offsets are being written in councils now, with industry associations arguing every parameter.
Who decides.
Agency for Natural Resources and Energy (資源エネルギー庁)
The Basic Energy Plan, power-market design, renewable auctions, and nuclear policy.
METI GX Group and GX Promotion Organization
GX-ETS design, benchmarks, allocation, and the GX bond investment framework.
Ministry of the Environment (環境省)
Climate targets, carbon credit schemes, and environmental assessment.
Nuclear Regulation Authority (原子力規制委員会)
Restart approvals and safety regulation.
OCCTO and regional utilities
Grid interconnection, capacity markets, and the connection queue.
LDP and coalition energy policy divisions
Where the political constraints on nuclear, offshore wind, and the carbon price are settled.
What can go wrong.
-
Being allocated under GX-ETS benchmarks written for domestic incumbents, or missing the window to shape them.
-
Offshore wind and renewable auction rules changing between rounds.
-
Grid connection timelines and curtailment rules that undermine a project’s economics.
-
Subsidy and contract-for-difference criteria that favor domestic supply chains.
Engagement needs.
- 01
Submit evidence to the ANRE and GX councils on benchmarks, allocation, and auction design while the parameters are open.
- 02
Work through the relevant industry association, and where necessary form a coalition, because METI consults associations first.
- 03
Engage the LDP energy divisions and the Diet committees where the political trade-offs are made.
- 04
Track budget requests and the GX investment framework to time subsidy applications.
