Japan's GX-ETS: mandatory emissions trading, with a price band of ¥1,700–¥4,300
Since April 2026, companies emitting 100,000 tonnes of CO2 or more must hold allowances for their emissions. Allowances are allocated free; credits can cover up to 10%; and a government-set price band limits the cost. The first filing, allocation and surrender all fall in 2027–28.
In brief
Japan's mandatory ETS began in FY2026 (April 2026) and covers companies with direct CO2 emissions of 100,000 t or more — about 300–400 companies, nearly 60% of national greenhouse gas emissions.
For FY2026 the reference ceiling is ¥4,300 and the adjustment floor ¥1,700 per tonne; from FY2027 both rise by 3% plus expected price inflation each year. A shortfall left unsurrendered costs the ceiling price × 1.1 (¥4,730 in FY2026).
Allowances are free: by sector benchmark or by past emissions cut 1.7% a year (0.3% for process emissions). J-Credits and JCM credits may cover up to 10%.
Because FY2026 is a transition year, filing and allocation move to FY2027, the allowance market opens around autumn 2027, and the first surrender is due 31 January 2028.
Prices and benchmarks
The official price band sets the limits. Government J-Credit tenders (last held in 2023) are the only official price history for credits.

The floor and ceiling apply to ETS allowances, not to these credits; they are drawn only for scale. The government stopped running tenders after the 14th (May 2023); June 2020 had no energy-saving winners.

How it works
The yearly cycle once the system is running (FY2026 shifts one step later).
File → allocate → trade → surrender
- Step 1
File a target
Covered companies report an emissions target and transition plan, verified by a registered body.
- Step 2
Receive free allowances
By sector benchmark, or past emissions cut 1.7% a year (0.3% for process emissions).
- Step 3
Trade surplus and shortfall
Allowances may be traded between companies; speculative trading is prohibited.
- Step 4
Surrender by 31 January
Hold allowances equal to verified emissions; up to 10% may be J-Credits or JCM credits.
- Step 5
If still short
Pay a charge: unsurrendered volume × ceiling price × 1.1.

Credits and offsets
Credits help meet the obligation within a fixed limit; the price band bounds the cost.

Frequently asked questions
When did Japan's mandatory emissions trading start?
In FY2026, from April 2026. The Act amendment was promulgated on 4 June 2025 and took effect on 1 April 2026, after a voluntary phase in FY2023–FY2025.
Which companies must take part?
Companies whose direct CO2 emissions average 100,000 tonnes or more over the previous three fiscal years — about 300–400 companies, nearly 60% of Japan's greenhouse gas emissions. Only direct CO2 (Scope 1) counts.
What are the price ceiling and floor?
For FY2026 the reference ceiling is ¥4,300 and the adjustment floor ¥1,700 per tonne of CO2. From FY2027 to FY2030 each year's price is the prior year's price × (1.03 + the projected change in the corporate goods price index).
What happens if a company is short of allowances?
It must surrender allowances equal to verified emissions by 31 January of the following year. Any shortfall costs the ceiling price × 1.1, which is ¥4,730 per tonne for FY2026 (a calculated value).
Can J-Credits be used for compliance?
Yes. J-Credits and JCM credits may cover up to 10% of a company's emissions each year.
How are free allowances decided?
By government sector benchmarks where they exist (for example coal-fired power, LNG power, cement, paper), or by past emissions reduced 1.7% a year for energy-related CO2 and 0.3% for process CO2.
When does the allowance market open and when is the first surrender?
The market is expected to open around autumn FY2027. Because FY2026 is a transition year, filing and allocation happen in FY2027 and the first surrender is due 31 January 2028.
When do auctions start?
Paid allocation for power generators is set to start in FY2033. A fossil fuel levy on upstream suppliers is set to start in FY2028.
