Climate Integrateは、独立した気候政策シンクタンクです。気候政策に関する調査分析とコミュニケーションを通じて、政府・地方自治体・企業・市民の脱炭素の取り組みを支援しています。An independent climate policy think tank based in Japan.
📊 We’ve updated our Data Visuals page.
The latest confirmed data and policy developments are now reflected in:
GHG Emissions
・Japan's GHG Emissions and Targets (FY2024 Actuals)
・Japan GHG emissions and pathway to net zero (base year 2013)
・GHG emissions breakdown (FY2024)
Electricity (General)
・Power generation mix scenarios
・Electricity mix and breakdown of renewables in FY2024 (Final figures)
Corporations
・GX-ETS Phase 2 (FY2026–)
・GX-ETS Phase 3 (FY2031?–)

[What is GX-ETS?]
Carbon prices under GX-ETS (Japan’s emissions trading system) are expected to remain low in the early years, then rise steeply in the 2040s.
That may weaken incentives for early emission cuts, while shifting a heavier burden onto future generations.

Our analysis of J-POWER illustrates that the GX-ETS benchmark can remain relatively lenient even when it requires emission reductions.
The required 2030 emissions level remains less ambitious than J-POWER’s own target, which is itself not aligned with Japan’s NDC.
This raises broader questions about whether the benchmark standards are ambitious enough to ensure its alignment with the NDC by 2030.

Our analysis of JERA suggests that under the current GX-ETS benchmark design, JERA’s required 2030 emissions level could be higher than its current emissions.
For LNG-heavy utilities, the benchmark becomes more lenient as the all-thermal benchmark gains weight.
This shows how the current design may allow compliance without ensuring absolute emission reductions.

📈Key findings from our report:
• Climate and energy budget totals 4.7 trillion yen, 3.3% of 140 trillion-yen total government budget, including initial and supplementary budgets
• Renewables account for just 3% of the total, down from FY2025
• Energy efficiency dominates at 52%, with AI/semiconductors, largest item in this category, tripled from last year.
• Issuance amount of Climate Transition Bonds is on a downward trend.

Our new report “Japan’s Spending Plan for Climate and Energy 2026” is out.
This report shows our independent analysis of Japan’s FY2026 climate and energy budget and the status of Green Transformation (GX) investments.
This marks our third annual government budget analysis, starting in FY2024.
