China Expands Carbon Market to Cement and Aluminum: 5 Key Compliance Takeaways for Foreign Investors
On March 21, 2025, China’s Ministry of Ecology and Environment (MEE) formally announced that the national Emissions Trading Scheme (ETS, 全国碳排放权交易市场, quánguó tàn páifàng quán jiāoyì shìchǎng) will include the cement and aluminum sectors beginning with the 2024 compliance cycle, adding approximately 350 million metric tons (Mt) of CO₂ to the roughly 4.5 billion Mt already covered under the world’s largest carbon market. For foreign executives operating or investing in China’s industrial supply chains, this expansion signals new compliance obligations, verifiable carbon accounting requirements, and rising operational costs that demand immediate attention.
1. What the Expansion Means for Foreign-Invested Enterprises
China’s national ETS initially launched in July 2021 covering only the power generation sector — approximately 2,162 entities accounting for about 40% of national CO₂ emissions. The new inclusion of cement (水泥行业, shuǐní hángyè) and aluminum (铝行业, lǚ hángyè) extends mandatory compliance to roughly 220 additional enterprises in the lime-based building materials sector and 90+ integrated smelters in the non-ferrous metals industry. The total emissions under the ETS now approach 5 billion Mt annually — a figure larger than the entire annual emissions of the European Union.
Foreign-funded manufacturers operating 外商独资企业 (WFOE, wàishāng dúzī qǐyè) plants in these sectors are now legally obligated to report verified emissions data by June 30, 2025, and surrender sufficient carbon allowances by December 31, 2025, for the 2024 reference year. Non-compliance triggers fines starting at 50,000 RMB for each unverified data point and daily penalties of 5,000–10,000 RMB for delayed allowance surrender.
2. Cement Sector — New Compliance Burdens and Cost Scenarios
The cement industry is China’s third-largest industrial emitter after power and steel, responsible for around 1.2 billion Mt of CO₂ — roughly 13% of national emissions. Under the ETS inclusion, each cement facility with annual greenhouse gas emissions exceeding 26,000 tons of CO₂ equivalent (tCO₂e) must register, submit a monitoring plan, and undergo third-party verification. For a typical 5,000-ton-per-day clinker production line, annual compliance costs — including verification fees, internal data systems, and potential allowance shortfall purchases — are estimated at 800,000–1.2 million RMB.
Allowance allocation for cement will largely follow the benchmark-based approach used in the power sector, meaning plants with emissions intensity above the sector median will face significant uncovered costs. Industry analysts at the China Building Materials Federation project that 30–40% of cement facilities may need to purchase additional allowances in the first compliance year, with prices expected to trade between 60 and 85 RMB per tCO₂ in 2025. A plant emitting 1.5 million Mt annually with an intensity 10% above benchmark would need to buy roughly 150,000 allowances, costing 9–12.75 million RMB.
3. Aluminum Sector — Inclusion and Integration Challenges
China’s aluminum production — roughly 41 million tons in 2024, or 58% of global output — generates approximately 450 million Mt of CO₂, most of it from coal-fired electricity used in electrolysis. The ETS expansion requires all primary aluminum smelters with capacity over 100,000 tons per year to participate, covering an estimated 90% of domestic production. For foreign-backed joint ventures (中外合资企业, zhōngwài hézī qǐyè) in this sector, the most critical requirement is that emissions data must include Scope 2 (purchased electricity) and Scope 3 (raw materials) calculations for the first time in a mandatory scheme.
The practical impact is immediate: aluminum producers historically purchased coal-based grid electricity at an average of 0.40–0.50 RMB/kWh, translating to an embedded carbon cost of roughly 30–40 RMB per ton of aluminum under current pricing. With allowance costs added, total carbon-related expenses for an integrated smelter could reach 120–180 RMB per ton of aluminum by 2026. For a 500,000-ton-per-year foreign-funded smelter, that represents an incremental cost of 60–90 million RMB annually — a material hit to margins that will likely be passed downstream to automotive, aerospace, and electronics buyers.

5. Actionable Compliance Steps for Foreign-Invested Plants
Foreign executives with cement or aluminum production in China must treat the ETS expansion as a strategic risk, not just a compliance cost. Below are the immediate requirements:
- Register in the national ETS registry — All covered entities must create an account on the China Carbon Emissions Registration and Trading System (全国碳排放权注册登记结算系统) by April 30, 2025. Late registration carries a 50,000 RMB fine per week and prevents allowance trading.
- Submit a monitoring plan — Detailing emissions sources, calculation methodologies (mass balance or direct measurement), and frequency of data collection. This plan must be approved by a provincial MEE office within 60 days of submission.
- Appoint a qualified third-party verifier — Only Chinese-accredited verification bodies (39 firms currently approved for power sector, expanding to cover cement and aluminum) can certify annual reports. Expect verification costs of 150,000–300,000 RMB per facility per year.
- Begin pre-compliance allowance trading — The national market currently trades only spot allowances, with average daily volume of 300,000–500,000 tons. Foreign-invested entities should assess their anticipated shortfall and consider buying allowances early to avoid year-end price spikes that historically have added 15–25% cost premiums.
Decision framework: If your facility’s emissions intensity is above the sector median, purchase allowances immediately and invest in abatement. If your facility’s intensity is below the median, sell surplus allowances in Q3 2025 when liquidity is highest.

7. Strategic Implications for Foreign Executives
The ETS expansion is not a one-time event — MEE has signaled that steel, petrochemicals, and paper production will follow by 2027–2028, ultimately covering 8,000+ entities and 7+ billion Mt of CO₂ annually. For foreign-invested industrial firms in China, this creates a multi-year compliance cost wave that will affect procurement, logistics, and end-product pricing. Companies that build internal carbon management systems early will gain competitive advantage — those that wait risk margin erosion and regulatory penalties.
Specifically, foreign executives should work with their China legal and operations teams to: (1) map all entity-level emissions against the new thresholds, (2) model allowance costs under different carbon price scenarios (60–100 RMB/tCO₂ by 2026), and (3) evaluate abatement investment payback periods for technologies such as alternative fuels in cement kilns or inert anode technologies in aluminum smelting. The cost of compliance is material, but the cost of non-compliance — including reputational risk with Chinese regulators — is far higher.
