Funding recovered, but remains below its peak
Climate-tech startups in Southeast Asia raised $166 million in disclosed equity funding in 2025, up 10% from $152 million in 2024. The total remained well below the 2023 peak of $288 million.
Across 2018 to mid-2026, the region attracted approximately $1.1 billion through 268 disclosed rounds. Investment is increasingly concentrated in solid-waste management and smart-grid technology.
Singapore captures most regional investment
Singapore accounts for about 79% of cumulative climate-tech funding in the region, or $872 million. Indonesia has attracted around $162 million and Vietnam approximately $53 million over the same period.
Funding in 2026 had started slowly, with four disclosed rounds worth roughly $17 million, all at seed stage.
Where capital goes, climate-tech jobs follow
The concentration of investment affects where companies can scale and hire. Singapore-based waste-tech and smart-grid businesses have greater access to capital for engineering, product and commercial roles than many peers in Jakarta or Hanoi.
This reinforces Singapore's position as the region's main climate-tech employment hub, even though the waste, grid and infrastructure problems these companies address extend across Southeast Asia.
