Renewable Energy, EVs, Batteries
Contribution to FDI
Green sectors in ASEAN, comprising renewable energy, electric vehicles (EVs), and batteries, play an increasingly important role in shaping foreign direct investment (FDI), although their contributions are often embedded within broader sectors such as manufacturing, energy, and infrastructure. While traditional sectors like finance and manufacturing dominate overall FDI shares, green sectors contribute both directly and indirectly through supply chain integration and industrial upgrading. EV and battery investments are largely captured under manufacturing FDI, which experienced strong growth driven by automotive and high-tech supply chains. Renewable energy contributes more through infrastructure and electricity-related investments and plays a critical enabling role by supporting sustainable industrial operations.
Multinational enterprises increasingly consider access to clean energy as essential when making location decisions, making renewable energy an indirect but influential driver of FDI. Battery investments further strengthen ASEAN’s position in global value chains by linking upstream resource extraction with downstream manufacturing. Together, these three segments form an interconnected ecosystem that enhances ASEAN’s attractiveness as a destination for sustainable and high-value investment. Although green sectors may not yet constitute the largest share of FDI by volume, their strategic importance is rising rapidly due to their role in transforming production systems and enabling long-term competitiveness.
Current Trend
The current trend in ASEAN’s green sectors reflects strong expansion driven by industrial demand, policy support, and supply chain transformation. EV-related investment is growing rapidly, particularly across automotive manufacturing, battery production, and supporting infrastructure. Major multinational enterprises have established or expanded production facilities across the region, with key hubs emerging in Indonesia, Thailand, Malaysia, and Viet Nam. Battery investments are expanding across the full value chain, from upstream processing of critical minerals to downstream manufacturing and assembly. At the same time, renewable energy investment presents a more mixed picture. While demand for clean energy continues to grow significantly, investment flows—especially those relying on infrastructure financing—have been more volatile, reflecting global financial conditions. Despite this, renewable energy deployment is increasing, supported by industrial demand and government initiatives. Across all three sectors, there is a clear trend of integration. EV production is linked closely with battery manufacturing and renewable energy supply, forming a coordinated ecosystem. Governments are also actively promoting these sectors through industrial policies, investment incentives, and sustainability frameworks. Overall, green sectors represent one of the fastest-evolving areas in ASEAN’s investment landscape, driven by both structural demand and strategic policy direction.
Driving Factor
The growth of green sector investment in ASEAN is driven by a combination of economic, policy, and structural factors. One of the most significant drivers is rapid industrialization and rising energy demand, particularly from manufacturing, digital infrastructure, and urban development. This creates a strong need for renewable energy and sustainable transport solutions. The transition toward low-carbon economies is another key factor, as governments and multinational enterprises adopt climate commitments and decarbonization strategies. EVs and batteries are central to this transition, driving demand for new production facilities and supply chain investments. Policy support plays a crucial role, with governments implementing incentives such as tax benefits, regulatory reforms, and infrastructure development programs to attract investment. Regional frameworks and national strategies further reinforce this momentum by prioritizing green growth sectors. Resource availability also contributes to investment attraction, particularly in batteries, where access to key materials supports upstream and downstream value chains. In addition, global supply chain restructuring encourages companies to diversify production locations, positioning ASEAN as an alternative hub. Technological advancements, including automation and digitalization, further enhance competitiveness. Together, these drivers create a strong foundation for sustained growth in green sector investment across ASEAN.
Outlook
The outlook for green sector investment in ASEAN is highly positive, with strong growth expected across renewable energy, EVs, and batteries over the medium to long term. These sectors are projected to become increasingly central to the region’s FDI landscape as global demand for sustainable production and low-carbon technologies continues to rise. ASEAN’s strategic position within global supply chains, combined with its growing domestic markets and supportive policy environment, provides a strong foundation for future investment. EV and battery ecosystems are expected to expand significantly, driven by increasing adoption, technological advancements, and continued investment from multinational enterprises. Renewable energy will also become more prominent, particularly as governments strengthen targets and infrastructure to meet climate commitments. However, several challenges remain, including infrastructure gaps, financing constraints, and the need for skilled labour and technological capabilities. Addressing these issues will be critical to sustaining growth. Regional coordination and policy harmonization will also play an important role in strengthening ASEAN’s competitiveness. Despite these challenges, the integration of renewable energy, EVs, and batteries into a unified green ecosystem positions ASEAN as a key global hub for sustainable investment and production, supporting long-term economic and environmental objectives.
