Carbon markets are emerging as a critical instrument for accelerating decarbonisation across Asia, mobilising private capital while supporting national climate commitments. For ASEAN, the region’s diverse landscape presents opportunities for greater alignment, knowledge sharing, and cross-border participation throughout the region. 

In Malaysia, that ambition has taken institutional form with the launch of the Malaysia Carbon Market Association (MCMA) under the ASEAN-Business Advisory Council Malaysia’s 2025 priorities. Established as a non-profit body, MCMA provides a unified platform to represent national carbon market interests and support policy developments. Its nine founding members bring together leading domestic and international players from the public and private sectors, including Yinson, Bursa Malaysia Berhad, Sarawak Energy Berhad and Petroliam Nasional Berhad (PETRONAS).  

Ahead of Malaysia’s ASEAN Chairmanship 2025 at COP 29 in Baku, MCMA moved quickly to anchor regional alignment, signing a Memorandum of Collaboration (MoC) with peer associations including the Singapore Sustainable Finance Association (SSFA), the Indonesia Carbon Trade Association (IDCTA), the ASEAN Alliance on Carbon Market (AACM), and the Thailand Carbon Market Club (TCMC). 

The collaboration aimed to develop a unified ASEAN Common Carbon Framework (ACCF) to create shared expectations around market design, transparency, and cooperation for carbon trading. One year later, the framework marked a milestone at COP30’s ASEAN Pavilion, with growing engagement from governments, market operators and financiers. 

What began as a coordination effort is now moving decisively toward action with pilot projects, regulatory dialogue and infrastructure planning taking centre stage. As ASEAN accelerates its energy transition, the ACCF is increasingly being viewed as the foundation for building confidence among investors, regulators and communities alike. 

From regional alignment to coordinated market action 

ASEAN has the potential to become a global hub for carbon markets and is poised to supply carbon credits to international buyers, but it’s critical for the region to work together. Without coordination, the region risks ending up with a patchwork of fragmented markets that limits efficiency and scale.

This is where the ACCF comes in, aiming to harmonise standards and establish credibility to ensure that ASEAN credits are recognised as high quality in global markets. To this end, the ACCF was designed to address common regional challenges that no country can solve alone, including mismatches in supply and demand, limited liquidity, and financing.  

As such, the ACCF is structured around three core Workstreams – Supply & Demand, Market Infrastructure, and Strategic Communications & Capacity Building. With this robust foundation, the ACCF made significant strides towards operationalising a regionally aligned, high-integrity carbon market ecosystem last year. 

Over the course of four Steering Committee meetings in 2025, ASEAN member states advanced a shared governance structure, initiated a voluntary endorsement pathway for pilots, and built consensus on regional deliverables. By year-end, the ACCF had finalised technical outputs including an updated roadmap, pilot pipeline, and a regional baseline alignment study. 

Taken together, these developments signal growing political will and private sector readiness to build an interoperable carbon architecture tailored to ASEAN needs while connected to global climate finance. Discussions at COP30 underscored that the ACCF is no longer a conceptual blueprint but moving towards coordinated implementation.  

Designing trustworthy markets for a complex, multi-speed region 

As the ACCF enters its next phase, the focus of the three workstreams is now shifting toward scaling pilots, deepening governmental engagement, and expanding market interoperability. 

The Supply and Demand track is strengthening the foundations of ASEAN’s carbon market. Priorities include clearer regional guidance on claims, mapping recognised crediting methodologies and aligning with Article 6 of the Paris Agreement, which provides the framework for countries to apply carbon credits toward their nationally determined contributions (NDCs). The workstream also examines blended finance mechanisms to de-risk project development, while mapping project pipelines and demand across corporates, financial institutions and compliance schemes to address persistent supply demand imbalances.  

Market infrastructure is emerging as a defining priority. Interoperable registries, transparent accounting and common safeguards will be critical to enable cross border transactions and attract global buyers. Trust sits at the centre, extending beyond investors to host communities and policymakers focused on environmental integrity and social outcomes. 

Capacity building will underpin progress, equipping regulators, developers and corporates to participate with confidence. Meanwhile, strategic communications are helping to clarify how carbon markets fit within national strategies to complement, rather than replace, domestic decarbonisation efforts. 

If successful over the next five years, the ACCF should deliver clearer regional guardrails that reinforce national policies, tangible interoperability pilots, and credible cross border transactions. Together, these steps can unlock greater investment into high integrity projects that generate real benefits for communities and ecosystems across ASEAN. 

Utilities and transition finance step into the spotlight 

Alongside policy coordination, utilities across the world are developing financing frameworks to channel capital into credible, science-based decarbonisation pathways that include carbon offsets. This reflects a growing recognition that decarbonising existing assets and scaling new low-carbon infrastructure must proceed in parallel.

In fact, Tenaga Nasional Berhad (TNB) became the first utility in ASEAN to launch a Transition Finance Framework, reflecting Malaysia’s proactive approach to carbon management. Through this framework, TNB can utilise various financing instruments to engage in sustainable finance transactions (SFTs) in the form of loans or sukuk.   

The proceeds can be allocated to several eligible categories spanning renewable energy projects, energy efficiency initiatives, affordable basic infrastructure and services, clean transportation projects and low carbon power generation projects in support of TNB’s overall sustainability strategy and Energy Transition Plan.  

TNB’s framework illustrates how leading utilities are structuring investments to decarbonise existing assets while scaling clean energy. Similar approaches globally include Ørsted’s Green Finance Framework, Enel Group’s Sustainability-Linked Financing Framework and EDF’s Green Financing Framework. 

Beyond utilities, transition finance frameworks are also being adopted across other emissions-intensive sectors like steel, cement, transport, and shipping. Companies including Tata Steel and Holcim have introduced transition-linked financing structures that tie capital access to clearly defined decarbonisation milestones. 

These instruments reflect a growing recognition that transition finance and carbon markets must evolve in tandem, and anchored by integrity, disclosure and governance. Within ASEAN, such frameworks can reinforce the ACCF’s objectives by demonstrating how corporates translate regional principles into bankable projects on the ground. 

Towards credible, scalable carbon markets in ASEAN 

As ASEAN’s energy transition gathers pace, the ACCF is poised to become a cornerstone of regional climate architecture.

As ASEAN’s energy transition gathers pace, the ACCF is poised to become a cornerstone of regional climate architecture. Its evolution from alignment to action highlights the region’s growing confidence in shaping markets that reflect local realities while meeting global climate standards. 

Pilot projects, regulatory harmonisation and infrastructure development over the coming years will be critical for ASEAN to unlock large-scale private investment. For utilities, governments and investors alike, the framework offers a common language for navigating carbon markets in a complex, multi-speed region. 

With sustained collaboration, the ACCF could help transform ASEAN’s carbon ecosystem from a patchwork of initiatives into a trusted engine for decarbonisation. In doing so, it would reinforce ASEAN’s position as a proactive architect of climate solutions, and a compelling destination for transition capital in the decades ahead.
