Regional spotlight: Carbon markets & offsets integrity in China — what's different and why it matters

China operates the world's largest carbon market by covered emissions, yet it remains one of the least understood among international climate finance participants. The national emissions trading scheme (ETS), launched in July 2021 and expanded significantly through 2024 and 2025, now covers approximately 5.1 billion metric tons of CO2 annually across power generation, cement, aluminum, and steel sectors. That figure dwarfs the EU ETS, which covers roughly 1.4 billion metric tons. But scale alone does not determine effectiveness. China's carbon market operates under fundamentally different design principles, enforcement mechanisms, and political dynamics than its Western counterparts, and understanding those differences is essential for any founder, investor, or policy professional engaging with Chinese climate commitments or cross-border carbon mechanisms.

Why It Matters

China accounts for approximately 30% of global greenhouse gas emissions, making the integrity and ambition of its carbon pricing mechanisms a determinant of whether global temperature targets remain achievable. The national ETS is not merely an environmental regulation; it is a tool of industrial policy, energy security strategy, and geopolitical positioning. For founders building carbon accounting, trading, or verification platforms, China represents both the largest addressable market and the most structurally distinct. For investors evaluating carbon credit quality across jurisdictions, Chinese offset programs (known as CCERs, or China Certified Emission Reductions) carry different risk profiles than credits generated under Verra, Gold Standard, or Article 6 frameworks. And for multinational corporations with operations or supply chains touching China, the interaction between domestic compliance obligations and international disclosure requirements (SEC, CSRD, ISSB) creates compliance complexity that demands regional expertise.

The Chinese government's December 2024 announcement that it would expand mandatory ETS coverage to six additional industrial sectors by 2027, and its January 2025 restart of the CCER voluntary offset program after a seven-year suspension, signals a new phase of market development. These decisions will shape carbon pricing dynamics across Asia and influence the viability of cross-border carbon adjustment mechanisms including the EU's Carbon Border Adjustment Mechanism (CBAM).

Key Concepts

China's National ETS operates as an intensity-based cap-and-trade system rather than an absolute cap system. Covered entities receive allowances based on emissions intensity benchmarks (tons of CO2 per unit of output) rather than fixed tonnage caps. This design reflects China's priority of economic growth alongside emissions reduction: a facility can increase total emissions while remaining compliant if its output grows faster than its emissions. The system covers more than 2,200 power generation entities, with cement, aluminum, and steel added in phased rollouts through 2024 and 2025. The Ministry of Ecology and Environment (MEE) serves as the primary regulator, with provincial ecological environment departments handling verification and enforcement.

China Certified Emission Reductions (CCERs) are China's domestic voluntary offset credits, analogous to Verified Carbon Units (VCUs) under Verra or CERs under the Clean Development Mechanism. The CCER program was originally launched in 2012 but suspended in March 2017 due to concerns about credit quality, additionality, and registry integrity. The program was formally restarted in January 2025 with revised methodologies covering four initial project categories: afforestation and reforestation, solar thermal power, offshore wind, and mangrove ecosystem conservation. Covered ETS entities may use CCERs to offset up to 5% of their compliance obligations, creating baseline demand for qualifying credits.

Measurement, Reporting, and Verification (MRV) in China's carbon market follows a structure distinct from international norms. Reporting is conducted by covered entities using standardized calculation methodologies rather than continuous emissions monitoring systems (CEMS), which are standard in the EU and increasingly required in North America. Third-party verification is performed by accredited organizations selected and supervised by provincial regulators. A 2024 MEE inspection found that 23% of sampled verification reports contained material errors or inconsistencies, prompting regulatory tightening including criminal penalties for fraudulent reporting introduced in February 2025.

The National Carbon Trading Registry operates from Wuhan, while the Shanghai Environment and Energy Exchange handles trading operations. Unlike the EU's single unified registry, China's system involves data flows between provincial reporting systems, the national registry, and the trading platform. This architecture has created data latency and reconciliation challenges, though a 2025 system upgrade reduced settlement cycles from T+5 to T+2.

What's Different in China

Intensity-Based Design Shapes Pricing Dynamics

China's intensity-based allocation system fundamentally alters market behavior compared to absolute-cap markets. Because allowances are tied to output, periods of economic growth can increase total allocation volumes, suppressing allowance prices regardless of aggregate emissions trends. The average allowance price on the Shanghai Environment and Energy Exchange fluctuated between RMB 60-105 ($8-15) per ton throughout 2025, roughly one-fifth of EU ETS levels. For founders building carbon pricing analytics or trading platforms, this means that price signals in China's market reflect efficiency improvements within sectors rather than economy-wide decarbonization pressure. Investors should note that low prices do not indicate policy weakness; they indicate a different mechanism design with different objectives.

State Capacity Drives Enforcement, Not Market Mechanisms

In Western carbon markets, enforcement relies primarily on financial penalties and market-based compliance incentives. In China, enforcement operates through a combination of administrative penalties, criminal liability (introduced under 2025 amendments to the Environmental Protection Law), and the social credit system for corporate entities. A cement company in Hebei Province was fined RMB 1.5 million and had its executives personally sanctioned in October 2024 for falsifying emissions data, the first criminal prosecution under the new framework. Provincial ecological environment departments conduct annual on-site inspections of covered entities, a level of direct regulatory engagement uncommon in Western market designs. For companies operating in China, this enforcement approach means that compliance risk extends beyond financial penalties to reputational and operational consequences including restrictions on government procurement eligibility and access to state-backed financing.

CCER Restart Creates Selective Offset Opportunities

The January 2025 CCER restart introduced methodological standards that are, in several respects, more restrictive than Verra or Gold Standard equivalents. The initial four approved methodologies (afforestation/reforestation, solar thermal, offshore wind, and mangrove conservation) were selected specifically to align with national priorities rather than maximize credit supply. Notably absent are avoided deforestation (REDD+), cookstove, and industrial gas destruction methodologies that remain prevalent in international voluntary markets. The MEE has signaled that additional methodologies for direct air capture, enhanced weathering, and methane destruction from coal mines may be approved during 2026, but the approval process involves multi-ministry review and public comment periods lasting 6-12 months.

For founders developing carbon credit platforms or verification services, the CCER market presents a distinct opportunity. Credit demand is structurally supported by the 5% offset provision in ETS compliance, creating a price floor linked to allowance values. However, credit supply is deliberately constrained by narrow methodology approval, ensuring scarcity. Early estimates suggest the CCER market could generate 100-200 million credits annually by 2028, representing $1.5-3 billion in transaction value at projected prices of $10-15 per credit.

What's Working

Provincial Carbon Market Pilots Inform National Design

Before the national ETS launch, China operated eight regional carbon market pilots (Beijing, Shanghai, Guangdong, Shenzhen, Hubei, Chongqing, Tianjin, and Fujian) starting in 2013. These pilots collectively covered approximately 3,000 entities and generated over $5 billion in cumulative trading volume. The pilots served as experimental laboratories, testing different allocation methods, sector coverage, and enforcement approaches. Guangdong's auction mechanism, Shenzhen's inclusion of buildings, and Beijing's coverage of indirect emissions each influenced national ETS design. Several pilots continue operating alongside the national market, creating opportunities for companies to test carbon management strategies in smaller, more accessible markets before engaging with national compliance obligations.

Digital Infrastructure for Carbon Data

China has invested heavily in digital MRV infrastructure, deploying satellite-based emissions monitoring, automated reporting platforms, and AI-powered anomaly detection across covered sectors. The MEE's Carbon Emissions Data Management Platform, upgraded in 2025, processes reporting data from over 5,000 entities in near-real-time and cross-references reported emissions against satellite observations, energy consumption data from State Grid Corporation, and production statistics from the National Bureau of Statistics. This multi-source verification approach, while imperfect, represents a more comprehensive data integrity framework than many international markets employ. For climate tech founders, this infrastructure creates demand for complementary tools including automated reporting software, anomaly detection systems, and integration platforms connecting Chinese and international carbon data systems.

International Cooperation Through Article 6

China has engaged cautiously but deliberately with Article 6 of the Paris Agreement, signing bilateral agreements with several Southeast Asian and African nations for cooperative carbon market approaches. The China-Kenya agreement, signed in September 2024, established a framework for cross-border carbon credit transfers that could serve as a template for broader Article 6 implementation. These bilateral arrangements position China as a potential hub for carbon credit flows across the Global South, competing with Singapore's Climate Impact X and other regional trading platforms. For climate finance professionals, understanding China's Article 6 strategy is essential for evaluating the future architecture of international carbon markets.

What's Not Working

Data Quality Remains the Core Challenge

Despite significant investment in digital infrastructure, emissions data quality in China's carbon market remains inconsistent. The MEE's 2024 inspection campaign identified material reporting errors at 23% of sampled facilities, ranging from incorrect emission factors to systematic underreporting of coal quality parameters. Several verification firms had their accreditation suspended following findings of inadequate review procedures. While the introduction of criminal penalties for data fraud has strengthened incentives for accurate reporting, the underlying challenge of standardizing measurement across thousands of diverse facilities with varying technical capacity remains substantial.

Low Price Levels Limit Decarbonization Signal

Allowance prices of $12-15 per ton of CO2 are insufficient to drive fuel switching from coal to gas (which requires roughly $30-50/tCO2 in Chinese power markets) or to incentivize investment in carbon capture and storage (which requires $60-100/tCO2). Current prices primarily reward operational efficiency improvements and penalize the least efficient facilities. While this is consistent with the market's design objectives, it means that China's ETS does not yet function as a meaningful driver of structural decarbonization. The MEE has indicated that the transition from intensity-based to absolute-cap allocation may begin in 2028, which would fundamentally alter price dynamics.

Limited Market Liquidity

Trading volumes in China's national ETS have remained concentrated around compliance deadlines, with multi-week periods of minimal activity between compliance cycles. Average daily trading volume in 2025 was approximately 1.5 million tons, compared to 35-40 million tons daily in the EU ETS. Low liquidity reduces price discovery efficiency, increases transaction costs for covered entities, and limits the development of derivative instruments needed for sophisticated risk management. Financial institution participation remains restricted, with banks and investment funds unable to trade allowances directly, a constraint the MEE is reportedly considering relaxing in 2027.

Action Checklist

• Map your organization's exposure to China's carbon market through direct operations, supply chain emissions, or cross-border product flows subject to CBAM

• Establish relationships with MEE-accredited verification bodies if operating covered facilities in China
• Monitor the expansion timeline for additional ETS sectors (petrochemicals, chemicals, paper, aviation expected 2027)
• Evaluate digital MRV platform requirements for Chinese emissions reporting, including compatibility with the MEE Carbon Emissions Data Management Platform
• Review Article 6 bilateral agreements for cross-border carbon credit transfer opportunities relevant to your portfolio
• Integrate Chinese carbon price scenarios into climate risk models, including potential price increases under absolute-cap transition
• Build internal capacity for navigating dual compliance obligations under Chinese ETS and international disclosure frameworks (SEC, CSRD, ISSB)

FAQ

Q: Can international companies participate directly in China's national carbon market? A: Currently, direct participation is limited to domestic entities with covered facilities. International companies with wholly foreign-owned enterprises (WFOEs) or joint ventures operating covered facilities in China are subject to ETS compliance obligations. International financial institutions cannot yet trade allowances or derivatives directly, though this restriction may be relaxed. Companies without covered Chinese operations can engage through CCER credit procurement or bilateral Article 6 mechanisms.

Q: How do CCER credits compare in quality to Verra VCUs or Gold Standard credits? A: The restarted CCER program applies rigorous additionality requirements and conservative baseline methodologies for its four approved categories. However, the program lacks independent governance comparable to Verra's or Gold Standard's multi-stakeholder boards, with methodology approval and registry management controlled directly by the MEE. International buyers should evaluate CCER credits on a methodology-by-methodology basis rather than applying blanket quality assessments.

Q: What is the outlook for carbon prices in China's ETS over the next five years? A: Most analysts project gradual price increases to RMB 150-200 ($20-28) per ton by 2028, driven by tightening intensity benchmarks and sector expansion. The transition to absolute caps, if implemented as indicated, could push prices to $30-50 per ton by 2030. However, pricing remains subject to policy intervention; the MEE has authority to release reserve allowances to prevent price spikes that could affect industrial competitiveness.

Q: How does China's carbon market interact with the EU's CBAM? A: The EU CBAM, fully operational from 2026, allows importers to deduct carbon costs already paid in the country of origin. Chinese exporters of cement, steel, aluminum, and other covered goods can claim deductions for ETS compliance costs, but only for direct (Scope 1) emissions and only where verifiable documentation exists. The current price differential between China's ETS ($12-15/tCO2) and the EU ETS ($68-75/tCO2) means that Chinese exporters face substantial CBAM liabilities on the uncovered price gap. This dynamic may accelerate China's transition toward higher carbon prices.
