ASEAN leverages industrial clusters to accelerate decarbonisation and growth

Southeast Asia stands at an inflection point: rapid economic and population growth is driving energy demand that, left unchecked, risks locking the region into a higher‑carbon industrial pathway. Home to more than 670 million people and a $3.8 trillion economy, ASEAN is projected to see energy demand more than double by 2050. The region’s ability to reconcile competitiveness, job creation and energy security with decarbonisation will shape its industrial future. A cluster‑driven model offers a practical route to that outcome.

According to the World Economic Forum, industrial clusters , concentrations of co‑located manufacturers, energy providers, logistics and innovation partners , can reduce the cost and time needed to deploy low‑carbon technologies. Shared infrastructure within clusters can accelerate renewables roll‑out, enable hydrogen and carbon capture utilisation and storage (CCUS), and anchor cross‑border power trade. Clusters also create focused platforms for workforce reskilling and for attracting long‑term industrial investment, aligning decarbonisation with competitiveness rather than treating them as competing priorities.

The cluster concept is being pushed from theory to practice across ASEAN’s diverse industrial landscape. Country strategies are adapting to local resource endowments and existing industrial strengths. Indonesia is leveraging vast nickel reserves and emerging mining‑to‑battery value chains to pursue an integrated EV battery hub, supported by initiatives such as a proposed “super grid” and green industrial parks in resource regions. Viet Nam is pairing its manufacturing ascent and semiconductor ambitions with aggressive offshore wind build‑out and grid modernisation to tackle curtailment. Malaysia is piloting hydrogen and CCS projects in energy‑dense corridors, while the Philippines is expanding renewables auctions alongside LNG and early hydrogen pilots. Singapore, despite heavy import dependence, is pursuing low‑carbon imports, Jurong Island redesign and clean‑finance tools to decarbonise hard‑to‑abate sectors.

Thailand illustrates how an established industrial base can be retooled. Long known as the “Detroit of Asia”, Thailand remains ASEAN’s largest automotive hub and is pursuing a shift to electric vehicle production while embedding low‑carbon infrastructure into its cluster strategy. Over 60% of the country’s power today is supplied by natural gas, a concentration that underlines both resilience and transition risk. The government’s target of 51% renewables by 2037 and the Smart Grid Master Plan aim to reduce that dependency. Existing clusters such as Map Ta Phut are piloting carbon capture and hydrogen blending; the Saraburi Sandbox is focused on cement decarbonisation, renewables and CCUS; and the Smart Park Industrial Estate in Rayong is designed to integrate clean energy, smart logistics and green manufacturing to serve the EV supply chain. Incentives for battery production and assembly are drawing global automakers and could anchor export‑oriented, lower‑carbon automotive value chains in the near term.

The cluster approach in ASEAN benefits from both scale and precedent. The World Economic Forum’s global initiative to transition industrial clusters towards net zero, launched in 2021 with Accenture and the Electric Power Research Institute, has grown rapidly. Industry engagement now spans dozens of clusters and scores of corporate and public institutions. According to the WEF, successive waves of cluster commitments have expanded participation, from a handful of pioneering zones to more than 30 clusters across multiple continents by early 2025, and the programme estimates collective potential to cut hundreds of millions of tonnes of CO₂‑equivalent annually while supporting economic growth and jobs. Industry modelling presented by the Forum suggests that well‑designed cluster interventions can deliver significant emissions reductions alongside GDP gains and employment protection or creation.

For ASEAN policymakers and industrial leaders the implications are concrete. First, clusters demand integrated planning: energy system upgrades, industrial land use, logistics and workforce development must be coordinated across ministries and private stakeholders. Second, finance needs to be tailored to cluster realities: aggregated demand and shared infrastructure lower unit costs but require new contractual and risk‑sharing structures to attract long‑term capital. Third, technology pathways must be pragmatic and place‑based, offshore wind, geothermal, hydrogen, CCUS and low‑carbon battery supply chains will play different roles in different member states. Finally, institutional capacity to govern cross‑border power trade and supply‑chain standards will be essential if clusters are to deliver both emissions cuts and competitiveness at regional scale.

There are challenges. Grid congestion, curtailment and infrastructure bottlenecks remain significant in several ASEAN markets; fossil‑fuel subsidies and existing asset vintages present transition costs and political economy hurdles; and the race to capture clean‑tech supply‑chain value raises questions about social outcomes, local content and equitable job transitions. Yet cluster models can mitigate many of these risks by concentrating investment where it yields the greatest combined industrial and emissions dividends.

For business leaders engaged in industrial decarbonisation, clusters offer a pragmatic lever for scaling impact quickly. By pooling demand, sharing infrastructure and coordinating skills development across firms and governments, cluster strategies can accelerate technology deployment, reduce unit costs and create resilient, export‑orientated industrial ecosystems. For governments, the appeal is that clusters can translate climate commitments into tangible regional development projects that protect jobs and national competitiveness.

As ASEAN enters what the WEF describes as a pivotal decade, the cluster approach will not, on its own, resolve all transition challenges. But evidence from the Forum’s global initiative and early pilot projects across the region shows clusters can materially narrow the trade‑off between growth and decarbonisation. For an economic bloc facing a near‑term surge in energy demand, that practical alignment of industrial strategy and low‑carbon investment may prove to be the most realistic path to securing both prosperity and climate goals.
