For manufacturers operating in Japan, this is not a distant sustainability aspiration — it is a regulatory and financial planning reality that starts affecting capital budgets now. This guide covers every mechanism, threshold, and compliance step you need to know.

The Act authorizes a JPY 20 trillion, 10-year GX Investment Budget — the largest climate finance commitment in Japan's history — funded through government-backed GX Economy Transition Bonds. It also establishes the legal basis for both the GX Emissions Trading Scheme (GX-ETS) and the carbon levy on fossil fuel importers. METI and the Ministry of Environment (MOE) jointly administer the Act. Uniquely, the GX Promotion Act is structured as a transition law: it sets the policy direction and funding authority but delegates technical implementation details — including the exact ETS threshold and levy rates — to subsequent Cabinet orders, creating regulatory uncertainty that manufacturers must monitor closely. ### GX-ETS — Emissions Trading Scheme (Voluntary Phase 2023–2025, Mandatory from April 2026) The GX Emissions Trading Scheme launched in a voluntary phase in April 2023 through the GX League program, with over 600 companies participating. The mandatory phase begins April 2026, targeting large emitters — the expected threshold is facilities emitting 50,000 tonnes or more of CO2-equivalent per year, though the precise threshold is subject to Cabinet order. Under the mandatory phase, covered emitters receive an initial allocation of emissions allowances and must surrender allowances matching their actual emissions each compliance year. Banking of surplus allowances is permitted; borrowing is restricted. Allowance prices are expected to reference the voluntary phase price discovery, which averaged in the low thousands of yen per tonne during the GX League phase. Manufacturers with multiple facilities must assess each facility independently against the threshold. ### Carbon Levy on Fossil Fuel Importers (FY2028 onward) Separate from the GX-ETS, the GX Promotion Act introduces a carbon levy applied at the point of fossil fuel import, starting at JPY 289 per tonne of CO2 in FY2028 and rising annually on a pre-announced schedule through FY2033 and beyond. The levy is structurally similar to a carbon tax but is collected from fossil fuel importers rather than end-users. In practice, importers will pass the cost through to industrial purchasers — manufacturers that are heavy consumers of coal, oil, or natural gas will see their energy costs increase progressively from FY2028. This creates a compounding incentive structure: manufacturers face both the direct ETS allowance cost (if above threshold) and the indirect carbon cost embedded in their energy prices. ### GX League and Voluntary Phase Participation The GX League is Japan's voluntary carbon pricing platform, operating from April 2023 through the end of FY2025 as a precursor to the mandatory GX-ETS. Over 600 companies representing approximately 40% of Japan's total CO2 emissions enrolled in the first participation round. GX League participants set voluntary reduction targets, trade emissions allowances among themselves, and access preferential government procurement scoring and priority access to GX Investment Budget grants. For manufacturers not yet above the mandatory ETS threshold, voluntary GX League participation offers strategic value: it builds internal emissions accounting capability, generates trading experience, and demonstrates climate credibility to customers and investors who are increasingly applying supply chain decarbonization pressure. ### Emissions Reporting Under the Act on Promotion of Global Warming Countermeasures (地球温暖化対策の推進に関する法律) Japan's existing emissions reporting framework — the Act on Promotion of Global Warming Countermeasures — already requires facilities emitting 3,000 tonnes CO2-equivalent or more per year to report annually to MOE and METI. Reported emissions data is published in a public database, making your facility's emissions visible to investors, customers, and NGOs. The GX-ETS mandatory phase will build on this existing reporting infrastructure, so companies already filing under the Global Warming Countermeasures Act will have their reported figures used as the baseline for ETS allowance allocation. Manufacturers with multiple sites should ensure consistent monitoring methodologies across facilities — inconsistencies create audit risk when mandatory ETS compliance begins. ### Green Innovation Fund and GX Investment Support The JPY 2 trillion Green Innovation Fund, administered by NEDO (New Energy and Industrial Technology Development Organization), provides grants and subsidized loans for decarbonization technology projects including green hydrogen, offshore wind, next-generation solar, and industrial process electrification. Application windows are competitive and sector-specific — manufacturers in steel, chemicals, cement, and paper are priority targets given their emissions intensity. Separately, the JPY 20 trillion GX Investment Budget provides financing support through GX Economy Transition Bonds for eligible projects. Companies participating in GX League receive preferential access to some funding streams. Manufacturers planning major capital investments in energy-intensive processes should evaluate GX fund eligibility before finalizing investment structures. ## Compliance process: step by step 01 Calculate your facility's annual CO2-equivalent emissions under the Act on Promotion of Global Warming Countermeasures. Identify all emission sources at each facility — stationary combustion, process emissions, and purchased electricity (Scope 2) — and apply the MOE/METI prescribed emission factors. If your facility emits 3,000 tonnes CO2e/year or more, you are already subject to mandatory annual reporting. Establish a consistent monitoring and metering plan to ensure your data is audit-ready for the GX-ETS mandatory phase in April 2026. 02 Determine whether you qualify for mandatory GX-ETS coverage starting April 2026. The expected mandatory threshold is 50,000 tonnes CO2e per year at the facility level, but confirm against the final Cabinet order when published. If you are above threshold at any facility, begin preparing for allowance allocation and surrender obligations now — METI will use historical reported emissions (from the Global Warming Countermeasures Act reporting) as the baseline for initial allowance allocation. 03 Evaluate GX League voluntary participation for FY2023–FY2025. Even if your facilities are below the mandatory threshold, GX League participation delivers strategic benefits: internal carbon accounting maturity, ETS trading experience before mandatory phase, preferential government procurement scoring, and first-mover positioning for GX Investment Budget grants. Enrollment for each GX League period opens through METI's GX League portal — review eligibility and target-setting requirements well ahead of each enrollment window. 04 Apply for Green Innovation Fund grants for decarbonization capital projects. If you are planning investments in process electrification, fuel switching, energy efficiency, or low-carbon manufacturing technology, assess eligibility for NEDO Green Innovation Fund calls. Applications require detailed technical proposals, emissions reduction projections, and milestone-based disbursement plans. Engage NEDO grant consultants early — competitive rounds are typically announced 3–6 months before the deadline. 05 Establish an internal carbon price for capital investment decision-making. Set an internal carbon price — METI recommends at least JPY 3,000–5,000 per tonne as a planning assumption, though leading companies use JPY 10,000+ — and apply it to all capital investment appraisals involving energy consumption or process emissions. This ensures investments made today remain financially sound as the carbon levy rises from FY2028 and ETS allowance prices increase through the 2030s. 06 Build a Scope 3 emissions inventory for supply chain disclosure. Japan's major listed companies are under increasing pressure from the Tokyo Stock Exchange's prime market sustainability disclosure requirements — and that pressure flows to suppliers. Build a Scope 3 inventory covering at minimum your purchased goods and services (Category 1) and use-of-sold-products emissions (Category 11). Align your methodology with the GHG Protocol Corporate Value Chain Standard. This positions you as a compliant supplier to large Japanese manufacturers accelerating their own net-zero supply chain programs. 07 Monitor METI GX roadmap updates for sector-specific requirements and timelines. METI publishes GX sector roadmaps for steel, chemicals, cement, paper, automotive, and electronics that specify decarbonization technology pathways, expected timelines, and policy support measures. Subscribe to METI's GX policy newsletter and review sector roadmap updates at least quarterly. Sector-specific requirements — such as green steel purchasing targets or low-carbon product labeling — may apply to your customers before they apply directly to you, creating de facto supply chain requirements ahead of regulatory deadlines. ## Frequently asked questions ### What is the GX Green Transformation plan in Japan? Japan's Green Transformation (GX) plan is a comprehensive government strategy to transition the economy away from fossil fuels while maintaining industrial competitiveness. Enacted through the GX Promotion Act in May 2023, the GX plan commits JPY 20 trillion over 10 years in public investment through GX Economy Transition Bonds, establishes the GX Emissions Trading Scheme (GX-ETS), introduces a carbon levy on fossil fuel importers from FY2028, and sets out sector-specific decarbonization roadmaps for energy-intensive industries. METI and MOE jointly administer the plan. It is explicitly designed as a transition mechanism — maintaining industrial growth while systematically raising the cost of carbon emissions over the 2020s and 2030s. ### When does the mandatory carbon ETS start in Japan? The GX-ETS moves from voluntary to mandatory in April 2026. The voluntary phase operated through the GX League from April 2023 through FY2025, with 600+ companies participating. From April 2026, facilities above the mandatory threshold — expected to be 50,000 tonnes CO2e per year, subject to final Cabinet order — must participate, receive allowance allocations, monitor emissions, and surrender allowances annually. The separate carbon levy on fossil fuel importers (JPY 289 per tonne CO2, rising annually) begins in FY2028. The two mechanisms operate in parallel: the ETS covers large direct emitters, while the carbon levy creates an indirect carbon cost embedded in energy prices for all manufacturers. ### Who must report emissions under Japan's Global Warming Countermeasures Act? Facilities emitting 3,000 tonnes of CO2-equivalent or more per year from energy use (Scope 1 + Scope 2 from purchased electricity) must file annual emissions reports under the Act on Promotion of Global Warming Countermeasures. Reports are submitted to MOE and METI and are published in a publicly searchable database. Companies with multiple facilities report each facility separately — a facility below 3,000 tonnes may still be included voluntarily. Listed companies are increasingly expected to report consolidated Scope 1, 2, and 3 emissions in their annual securities reports under Tokyo Stock Exchange prime market sustainability disclosure guidance, regardless of facility-level thresholds. ### What financial support is available for manufacturers under Japan's GX plan? Japan's GX plan offers several financial support mechanisms for manufacturers. The JPY 2 trillion Green Innovation Fund (administered by NEDO) provides competitive grants for decarbonization technology R&D and demonstration projects in priority sectors including hydrogen, offshore wind, next-generation solar, and industrial electrification. The broader JPY 20 trillion GX Investment Budget provides subsidized financing through GX Economy Transition Bonds for eligible low-carbon capital projects. GX League participants receive preferential access to some grant streams and preferential government procurement scoring. Additionally, METI operates sector-specific subsidy programs for energy efficiency improvements and fuel switching at industrial facilities — separate from and additional to the core GX mechanisms. **Disclaimer:** Educational resource only.
