About Climate Signal
"Why are we still 'solving' climate change if the was science settled decades ago?"
Climate Signal is a fortnightly deal intelligence newsletter for investors in climate and environmental markets. Global coverage, sharpened to an Asia-Pacific lens.
We serve investors, founders and interested parties alike as a regional data node, in a much bigger information web. Capital allocators do not need more noise. They need signal: the specific, sourced, checkable research, that tells you the bigger picture and which deals deserve your diligence hours, and which do not.
That means curation over volume, evidence over assertion, and an honest line about what the public record cannot tell us. We screen deals, we do not recommend them. We show our work and cite our sources so you can check us.
Southeast Asia's entire climate tech sector has disclosed around $1.1bn across 268 venture capital rounds in eight years as of 2025, with close to 80% of it landing in Singapore. That scarcity is why this exists. Expect the APAC share to grow as sourcing improves.
What we cover.
Six to eight deals a fortnight, across four pillars and a wildcard.
- 💰 Finance & capital flows. Fund closes, blended finance, debt for nature, grant allocation.
- ⚡ Energy transition & infrastructure. Renewables, Grid, storage, hydrogen, hard-to-industrial tech.
- 🌱 Nature, oceans & food systems. Regenerative ag, biodiversity tech, nature, sustainable fishing, soil and blue carbon, biodiversity credits, traceability.
- 🏗️ Adaptation & resilience. Risk analytics, parametric insurance, flood technology, water, fire, resilient infrastructure.
- 🎲 Wildcard. R&D stuff, bleeding edge and anything else that sparks
How we screen
Every deal runs the same checks. Green is validated by public evidence. Amber is real but conditional. Red is a flag. Grey means the public record can't tell us, and we say so rather than guess. Here's a quick example.
Dat Bike — $22M Series B
Vietnam · Electric mobility · Led by F.C.C, Rebright Partners
🟢 Traction 5 model generations, 20 owned service centres, 5x production scale-up in 2024
🟢 Investor quality Strategic lead in F.C.C, a Tokyo-listed components maker, not just financial VCs
🟡 Capital trajectory ~$51M over 6 rounds in 7 years. Aggressive, but matched to a legislated market
🟢 Policy fit Hanoi's Directive 20 mandates EV two-wheelers from 2026, and the fundamentals stand without it
⚪ What we can't see: revenue, margins, unit economics, valuation or deal terms. The March 2026 $4M round is attributed to a domestic securities firm that public reporting doesn't name. Thailand expansion is announced, not evidenced.
Screening, not diligence. A filter, not a verdict.
Free. Every fortnight. Five minutes. No paid tier yet.
Who writes this?
Luke Clark
I've been working in climate & environmental sectors across 10 years. First as a conservation biology MSc student and research assistant studying neotropical biodiversity and ecosystem regeneration. Then building Tech4Earth News, a side project that snowballed into helping climate tech startups book investor meetings and scale business development operations and now driving decarbonisation across public and private sectors at South Pole, one of the world's leading climate advisory firms and carbon market players. Day to day that means trading certificates in carbon and renewable energy markets, tracking industrial decarbonisation build-outs, and speaking directly to regenerative agriculture programmes across the region.
