Carbon Pricing in the ASEAN Region: Moving from ambition to architecture

Across Southeast Asia, carbon pricing is shifting from a theoretical commitment to an active policy architecture. Countries are at different stages, but the regional direction is increasingly clear: carbon pricing and carbon markets are becoming part of broader conversations on climate ambition, economic resilience, trade competitiveness, and investment.

When we look at the policy landscape, carbon pricing measures are already in place or being piloted across the ASEAN region: 
•    Indonesia has launched IDXCarbon, a national carbon exchange for trading carbon units, while developing and expanding carbon pricing measures, including emissions trading in the power sector.
•    Singapore's carbon tax stands at SGD 45 per tonne (roughly USD 35) in 2026−2027 and is set to reach SGD 50–80 per tonne (USD 39–63) by 2030.
•    Viet Nam is piloting its domestic carbon market through 2028, with full operation planned from 2029.
•    Thailand is developing its own emissions trading system (ETS) framework, with a pilot potentially launching in 2029.
•    Malaysia has announced plans to introduce a carbon tax as early as 2026, starting with iron, steel, and energy.
•    Other ASEAN members are exploring voluntary carbon markets, Article 6 cooperation, sectoral mitigation programs, and related readiness measures.

Globally, direct carbon pricing now covers 29% of greenhouse gas emissions through 87 carbon pricing instruments—47 carbon taxes and 40 ETSs—generating over USD 107 billion in public revenue in 2025. For ASEAN policy-makers, carbon pricing is no longer simply a domestic climate policy choice. It is increasingly linked to global economic integration, trade relationships, investment flows, and industrial competitiveness.

Momentum Is Not the Same as Readiness

While political momentum is growing, implementation readiness remains at different stages. Credible carbon pricing systems require clear legal mandates, institutional coordination, robust measurement, reporting, and verification (MRV) systems, transparent emissions and carbon credit registries, market confidence, and public trust. In several ASEAN member states, efforts to strengthen these foundations are advancing, although progress varies across agencies, sectors, and levels of government.

One of the most significant structural barriers is the continued presence of fossil fuel subsidies. Not only do they compete with carbon pricing instruments, but they can also directly undermine the price signal those systems are designed to create. Fragmented policy frameworks, limited MRV technical capacity, and underdeveloped emissions and carbon credit registries compound the challenge further.

Carbon pricing cannot be viewed as a stand-alone technical fix. It is embedded in broader governance challenges that demand long-term planning and deliberate sequencing across legal, regulatory, fiscal, and administrative systems.

Managing Competitiveness and Leakage Risks

ASEAN economies are deeply integrated into global trade and manufacturing networks, with significant exposure for energy-intensive sectors: steel, cement, chemicals, and electronics. As carbon costs rise at different speeds across jurisdictions, businesses in emissions-intensive and trade-exposed sectors may face growing pressure to relocate production or investment to countries with lower climate-related costs. This can weaken the competitiveness of domestic industries while doing little to reduce overall global emissions. However, these risks should not deter progress. They can be assessed through sectoral data, trade exposure, emissions intensity, and economic modelling—and managed through appropriate policy design, including ETS linkage, carbon cost containment measures, and border carbon adjustment mechanisms.

Durability Depends on Fairness

The long-term political viability of carbon pricing will be determined less by its technical design than by how its costs and benefits are distributed. If people only see and feel the cost without experiencing visible benefits, carbon pricing becomes politically fragile, particularly when costs are passed directly to consumers. 

Public support will depend heavily on how revenues are used.  For example, whether revenues flow back to households as dividends, fund clean energy access, or strengthen social protection programs, each approach sends a clear signal about whose interests the system serves.

With this in mind, policies and revenue-use plans must ensure gender and just transition considerations are built in from the start. Meaningful engagement with vulnerable groups, alongside businesses, workers, local communities, and civil society—all of whom will experience the transition differently—will provide valuable insights into implementation challenges and social impacts. It will also ensure policy-makers better understand distributional concerns, are able to communicate trade-offs transparently, and design policies that are both more equitable and politically durable.

Regional Coordination

Carbon pricing instruments are national by design, but their effectiveness is increasingly shaped by regional and global dynamics. A fragmented ASEAN approach risks inconsistent MRV standards, incompatible carbon market registries, and reduced collective leverage in responding to external mechanisms such as the EU Carbon Border Adjustment Mechanism.

Regional cooperation can help ASEAN countries move more effectively from policy ambition to implementation. Shared studies, technical exchanges, and knowledge-sharing platforms can strengthen institutional capacity while enabling countries to learn from both regional experiences and international best practices. Over time, cooperation on areas such as MRV, registry infrastructure, Article 6 operationalization, market oversight, and implementation sequencing could help reduce fragmentation and support greater market confidence across the region.

International experience, including the governance architecture and market oversight of the EU ETS, provides useful lessons for ASEAN member states in designing their own carbon pricing systems. 

Underlying all of this is a fundamental shift in how carbon pricing is being understood across the region. As a climate instrument, it is increasingly recognized as a structural feature of ASEAN's economic transition, one that will shape investment decisions, industrial strategy, energy systems, and social resilience for decades to come.

Ultimately, carbon pricing is not a stand-alone switch that governments can simply turn on. It is a policy system that must be carefully built—with credible institutions, reliable data, clear rules, fair use of revenues and benefits, inclusive engagement, and careful sequencing. When these elements come together, carbon pricing can move beyond being a technical mechanism and become a practical bridge between climate ambition, economic resilience, and a just transition across ASEAN.
 

These issues were at the centre of discussions during the session Carbon Pricing Design for ASEAN: Market Insights, Competitiveness, and Just Transition at the ASEAN Regional Workshop on Carbon Pricing and Carbon Markets, held on May 20−21, 2026, and co-organized by the European Union through the Technical Assistance Facility to the Green Team Europe Initiative (TAF-GTEI), the ASEAN Secretariat, the Brunei Climate Change Office, and the International Institute for Sustainable Development.
