For much of the past decade, carbon pricing in Asia was treated as a long-term ambition, something to be studied while industrial policy remained focused on growth and energy security. The European Union’s carbon border adjustment mechanism changed that calculation. Governments that had resisted mandatory carbon costs now face a commercial deadline: establish comparable domestic pricing or see domestic exporters pay carbon charges to a foreign trading partner. By 2025, the result is a patchwork of emissions trading systems, intensity-based mechanisms, and voluntary offsets. How Asian carbon markets work is less a single design than a set of compromises — most of them limiting carbon intensity rather than total emissions, which is where the divergence from Europe begins.
Why Asian Carbon Markets Look Different
China’s national emissions trading system is the largest in the world by the volume of emissions it covers, according to the International Carbon Action Partnership, but it does not cap total emissions. Instead, allowances are allocated per unit of output. As production expands, absolute emissions can rise even when the carbon intensity of each unit falls. This design choice reflects the political constraints that shape carbon pricing across much of Asia, where industrial growth and energy security remain central policy priorities.
South Korea runs a cap-and-trade system closer to the European design, with declining annual caps and auctioned allowances. Japan has layered a voluntary emissions trading scheme with a carbon levy and credit trading under its GX strategy. Indonesia, India, Vietnam, and Thailand are developing or piloting sectoral systems and voluntary frameworks. The regional picture is one of simultaneous acceleration and fragmentation.
For market participants, the distinction between intensity-based and cap-and-trade systems changes how prices should be read. A low carbon price in an intensity-based system does not necessarily signal weak ambition. It may reflect a design where abatement happens through technology standards and efficiency benchmarks rather than allowance scarcity. This also complicates the way carbon costs enter corporate accounting, particularly where firms track indirect emissions through mechanisms such as Scope 2 emissions.
The result is that comparing carbon prices across jurisdictions can mislead. A price of a few dollars per tonne in China’s power sector does not carry the same marginal abatement signal as a similarly priced allowance in the EU ETS, because the Chinese system constrains emissions per unit of output rather than total supply. Buyers and analysts need to look at benchmark tightening schedules and sector coverage, not just the trading price.
Intensity-Based Design in Practice
China’s approach illustrates the logic. By setting emissions benchmarks per unit of output and tightening those benchmarks over time, the system rewards efficient producers without penalising production growth. A steel plant that reduces emissions per tonne of steel benefits whether total output rises, stays flat, or falls. The mechanism incentivises efficiency without constraining scale.
The trade-off is that absolute emissions can continue rising when output grows faster than intensity improves. This has led to criticism that intensity-based systems lack the environmental certainty of absolute caps. Several Asian governments, however, treat carbon pricing primarily as an industrial modernisation tool, with emissions reduction as a secondary benefit rather than the sole objective.
The policy effect is measurable. Intensity benchmarks in China’s power sector have driven efficiency improvements across the coal fleet, and expanded coverage to aluminium, cement, and steel extends that pressure to heavy industry. The mechanism works differently from a European cap-and-trade system, but dismissing it as ineffective overlooks the structural changes already underway.
Benchmark-based allocation also differs from systems that allocate allowances based on historical emissions. Because a facility receives allowances in proportion to current output, the design reduces windfall profits but can create an incentive to maintain production even when demand weakens. This is one reason intensity-based markets tend to produce lower allowance prices than absolute caps; the constraint operates on efficiency rather than total volume.
Intensity targets also interact with the electricity sector in specific ways. Coal generators face a benchmark that rewards the most efficient units, while older, less efficient plants bear a higher cost per megawatt-hour. This shifts dispatch economics without directly limiting total coal generation, which is why the system’s effect on power sector emissions is less immediate than a cap would be.
CBAM and the Trade Dimension
CBAM has done more to accelerate carbon pricing in Asia than two decades of international climate negotiations. The mechanism applies a carbon cost to imports of cement, iron and steel, aluminium, fertilisers, electricity, and hydrogen based on the emissions embedded in production. For exporting nations, this creates a direct commercial incentive to establish domestic carbon pricing.
The logic is straightforward. If a country prices carbon domestically, the revenue stays within its own economy rather than flowing to the European Union as a border charge. This turns carbon pricing from an environmental policy choice into a trade competitiveness measure. Governments that were previously reluctant to impose carbon costs on domestic industry now face the prospect of those same costs being collected by a foreign trading partner.
Several Asian economies have responded by accelerating existing plans or launching new systems. Indonesia’s carbon exchange became operational in 2023. India is developing a carbon credit trading scheme with compliance obligations for designated sectors. Vietnam is piloting a crediting mechanism. The common thread is urgency driven by market access rather than by climate targets alone.
This trade-driven motivation creates different priorities from those in the EU ETS. Policymakers focus on building a system that European regulators accept as comparable, with emissions reduction operating as a parallel objective rather than the sole target. The implications extend to monitoring, reporting, and verification infrastructure, which many jurisdictions are still developing. The gap between policy announcement and operational capability remains wide.
Recognition and equivalence have become central negotiating issues. Asian governments are designing systems that can be documented and audited against European requirements, rather than copying the EU ETS architecture. This has accelerated investment in registries, emissions databases, and verification bodies, but building that institutional capacity takes time and technical capability that many jurisdictions are still assembling.
Country Pathways and Divergence
China is expanding sectoral coverage and may adopt hybrid or cap-based features for certain industries. The pace depends less on climate ambition than on the speed of economic restructuring. As the economy shifts from investment-led growth toward consumption and services, the tension between emissions caps and industrial output becomes less acute.
South Korea faces the challenge of aligning a relatively mature cap-and-trade system with industrial competitiveness concerns. Its export-oriented manufacturing sector means carbon costs that rise faster than those of regional competitors create commercial pressure. The policy response has involved adjustments to free allocation and cost-containment measures rather than abandoning the framework.
Japan’s GX strategy treats carbon pricing as an industrial policy instrument. Revenue from carbon pricing is directed toward industrial decarbonisation rather than returned through dividends or general expenditure. This framing resonates across much of Asia, where carbon pricing is often seen as a tool for modernising heavy industry rather than solely as an emissions reduction mechanism.
India’s approach is notable for its planned use of a carbon credit trading scheme alongside existing energy efficiency obligations. The design discussion centres on how to avoid double counting between renewable energy certificates, energy savings certificates, and the new carbon credits. Indonesia, meanwhile, has developed a carbon exchange that supports both compliance and voluntary trading, with sectoral coverage still being phased in.
Alongside compliance systems, the voluntary carbon market continues to evolve. Article 6 of the Paris Agreement has moved into operational implementation, opening the door for bilateral credit transfers between countries. Several Asian nations are positioning themselves as credit suppliers, though the quality and additionality of credits remain subjects of intense negotiation.
What the Next Phase Requires
Carbon pricing in Asia shows no sign of converging toward a single model. The economic structures, political constraints, and industrial priorities of the region’s economies are too diverse for a uniform approach. A more probable path is parallel development, with different systems gradually deepening coverage and tightening benchmarks while maintaining distinct architectural features.
Whether the next phase produces genuine price signals depends on how governments use the revenue. If carbon pricing revenue begins to reshape investment decisions rather than simply sheltering industry from border charges, the systems take on a different economic role. That question remains open across much of the region.
Thin liquidity remains a practical constraint in several systems. Many Asian carbon markets trade sparsely, with allowances held by compliance entities rather than by financial intermediaries. Without active secondary trading, prices reflect administrative benchmarks more than they reflect continuous marginal abatement decisions. That limits the usefulness of the price signal, even when the underlying policy is well designed.
What is already clear is that carbon pricing architecture is becoming a permanent feature of the region’s economic landscape. The institutions, registries, monitoring systems, and trading infrastructure being built today shape investment decisions well beyond the current policy cycle. Design choices about coverage, allocation methodology, international linkage, and revenue use carry consequences that extend past the immediate policy horizon.
