Recorded climate tech funding in Vietnam fell 52 percent in 2025 to $49.86 million across 33 transactions, from $104.20 million across 60 transactions in 2024, according to the “Vietnam Climate Tech Ecosystem Report 2026.”
The report is jointly conducted by New Energy Nexus Vietnam, an NGO; along with SNV Vietnam, World University Service of Canada, and RMIT University Vietnam, and Swiss EP.
The reports clarified the strong achievement in 2024 was lifted by a single $70 million Series A investment in Techcoop. Excluding the largest deal in each year, funding fell 19 percent, from $34.2 million to $27.86 million.
The reports identify a financing gap between early-stage grants and larger commercial rounds. No recorded deal closed in the $350,000 to $1 million range in 2025, compared with four in 2024. Women-founded enterprises were among the most affected because many face difficulty meeting collateral requirements and receiving dual-mandate support, the report showed.
Debt financing rose from $3 million to $20 million in 2025, driven by a facility for CME Solar, while equity funding fell sharply. Thao Tran, country director at New Energy Nexus Vietnam, said funders have capital for Vietnam’s climate start-ups and founders need it, yet no recorded deal closed in the $350,000-$1 million range in 2025.
The reports also describe a talent shortage. Of the enterprises surveyed, 73 percent ranked technical and engineering skills among their top three workforce needs, and 50 percent said these skills were the hardest to recruit. Lindsay Umalla, energy sector leader at SNV in Vietnam, said capital has arrived faster than the people needed to deploy it.
Women founded about a third of Vietnam’s active climate tech enterprises and received about 56 percent of recorded grant funding in 2025, but only about 1.7 percent of total recorded climate tech capital, the reports say.
The report also pointed out Energy Transition led sector funding in 2025 with $26.71 million, up 72 percent from 2024. It was the only sector to attract venture equity, debt and grants.
