Highlights:
  • Southeast Asia’s Climate Tech ecosystem attracted approximately $1.4B across 269 equity funding rounds between 2020 and May 2026, with Singapore accounting for nearly $1.1B of total funding.
  • Funding peaked at $288M in 2023 before declining to $152M in 2024 and recovering slightly to $166M in 2025, reflecting a more selective investment environment focused on companies with clearer paths to scale.
  • Early-stage funding increased from $108M in 2024 to $147M in 2025, highlighting continued investor interest in startups advancing beyond initial validation. ● Indonesia ($162M) and Vietnam ($53M) are emerging as mobility-and manufacturing-led Climate Tech markets, supported by EV production, battery supply chains, and energy-transition initiatives.
  • Solid Waste Management Tech ($105M) and Smart Grid ($97M) emerged as the most-funded Climate Tech sectors, driven by growing demand for circular-economy and energy-infrastructure solutions.

Overview of SEA Climate tech landscape

Tracxn, the global market intelligence platform for private company data, today released the Southeast Asia Climate Tech Report 2026. The report provides a comprehensive analysis of Southeast Asia’s Climate Tech ecosystem, covering funding trends, sector activity, policy developments, and emerging investment themes across SEA markets from 2020 to May 2026.

The report tracks approximately $1.4B in disclosed equity funding across 269 rounds and highlights an ecosystem increasingly shaped by electrification, renewable energy, grid modernisation, battery infrastructure, and industrial decarbonisation. Supported by rising policy momentum and infrastructure investment, Southeast Asia’s Climate Tech ecosystem is gradually evolving toward infrastructure- and deployment-led growth.

Capital Is Moving Toward Infrastructure and Scale-Up

Southeast Asia’s Climate Tech funding landscape is increasingly concentrating around infrastructure-oriented sectors linked to electrification, grid expansion, energy storage, and industrial transition. Singapore continues to anchor the region’s Climate Tech ecosystem, attracting nearly $1.1B of the region’s total funding since 2020, supported by its mature venture environment, sustainable-finance ecosystem, and carbon-market infrastructure.

At the company level, RWDC Industries, Beam, and Amperesand collectively accounted for nearly $500M in funding, highlighting how regional capital is increasingly consolidating around companies operating at deployment and scale-up stages. A similar pattern is visible across sectors, where a limited number of larger infrastructure-focused rounds are shaping category development and attracting follow-on investor activity.

Manufacturing and Electrification are Reshaping Regional Growth Markets

Beyond Singapore, Indonesia and Vietnam are emerging as Southeast Asia’s strongest manufacturing and mobility driven Climate Tech markets. Indonesia’s $162M funding base has been driven by EV manufacturing, charging infrastructure, and battery supply-chain expansion, supported by the country’s nickel reserves and energy-transition initiatives. Vietnam’s Climate Tech activity has accelerated around electric two-wheelers, renewable-energy deployment, and energy infrastructure expansion, led by companies such as Dat Bike.

A broader industrial transition is beginning to emerge across Southeast Asia, with Climate Tech investment gradually shifting from software-led sustainability solutions toward physical infrastructure, manufacturing capacity, and large-scale energy-transition deployment.

Infrastructure-Led Sectors Continue to Attract Investor Attention

Infrastructure-oriented sectors accounted for a significant share of Southeast Asia’s Climate Tech funding activity. Solid Waste Management Tech led with $105M across 34 rounds, followed by Smart Grid ($97M), Energy Efficiency Tech ($77M), Air Pollution Management Tech ($71M), and Renewable Energy Tech ($62M).

The sector mix highlights a broader evolution in regional Climate Tech priorities, with investors increasingly focusing on recycling infrastructure, battery recovery, grid integration, energy storage, carbon-market platforms, and industrial energy optimisation. As energy-transition programmes expand across SEA, infrastructure-led Climate Tech categories are expected to remain central to long-term capital deployment across the region.
