Climate tech VC funding 2026: market reset, capital concentration, focus shift
Climate tech venture funding totaled approximately $42 billion in 2025, down from 2022 peaks but stabilising. Capital concentration in fewer, larger rounds — average Series B+ check size at $60M. Battery storage + grid-scale tech + industrial decarbonisation dominating; mobility softening; agriculture + carbon removal rising. 2026 outlook: stable to growing.
In 50 words: Climate tech VC funding totaled ~$42 billion in 2025, down from 2022 peaks but stabilising. Capital concentration in fewer, larger rounds — average Series B+ check size at $60M. Battery storage + grid-scale tech + industrial decarbonisation dominating; mobility softening; agriculture + carbon removal rising. 2026 outlook: stable to growing.
The market reset
Climate tech VC funding trajectory:
- 2020: $25B
- 2021: $55B (peak frenzy)
- 2022: $80B (peak — driven by IRA + EV hype)
- 2023: $55B
- 2024: $48B
- 2025: $42B
- 2026 forecast: $45-55B (stabilising/growing)
The 2022-2024 contraction reflects:
- Higher interest rates reducing risk capital
- IPO market closures (only 1 major climate IPO in 2024)
- Several high-profile EV startup failures (Lordstown, Faraday Future, etc.)
- Solar deployment maturing — less venture risk
- General VC slowdown across all sectors
What's growing in 2026
Battery storage + grid-scale technology
- Long-duration storage (Form Energy, ESS Inc, Energy Vault)
- Grid software (AutoGrid, Stem, Sunverge — many already acquired)
- Power electronics + smart inverters
- Average Series B+ check: $80-150M
Industrial decarbonisation
- Green steel (H2 Green Steel raised $1.5B)
- Green cement (Brimstone, Sublime)
- Industrial heat (Antora Energy thermal storage)
- Process electrification
Carbon removal
- Direct Air Capture (Climeworks $650M, Carbon Engineering acquired)
- Enhanced rock weathering (Lithos Carbon, Inplanet, Travertine)
- Bio-based removal (Charm Industrial, Vaulted Deep)
- Ocean removal (Ebb Carbon, Equatic)
Agriculture + food
- Alternative proteins (after correction)
- Agricultural inputs (Pivot Bio, Indigo Ag)
- Methane reduction (Symbrosia, Blue Ocean Barns)
What's softening
Mobility / EVs
- Established players (Tesla, BYD) dominating; new entrants struggling
- Charging infrastructure consolidation (smaller players acquired or failing)
- Battery startup challenges (multiple liquidations)
Residential clean tech
- Solar installer consolidation (some bankruptcies)
- Smart home energy management — limited venture exits
- Heat pump distribution — slow margins
Voluntary carbon markets
- Several startup failures post-credibility crisis
- Some recovery underway with quality focus
Major investors
Top climate tech investors active in 2025-2026:
Pure-play climate funds:
- Breakthrough Energy Ventures (Bill Gates)
- Lowercarbon Capital
- Energy Impact Partners
- Generation Investment Management
- TPG Rise Climate
- BlackRock Climate Infrastructure
- Brookfield Asset Management Transition
Generalist VCs with climate practices:
- Sequoia, Andreessen Horowitz, Khosla Ventures, Founders Fund
- Most major VCs now have climate partners
Corporate VCs:
- Microsoft Climate Innovation Fund
- Amazon Climate Pledge Fund
- Stripe Climate
- Frontier (Stripe + Alphabet + others)
Geographic distribution
Climate tech VC by region (2025):
- US: 55%
- Europe: 25%
- Asia (ex-China): 10%
- China: 8% (likely understated; domestic deals less reported)
- Rest of world: 2%
India climate tech is growing but small base — major Indian climate startups: BluSmart, Euler Motors, Battery Smart, ReGrid, Loop Mobility.
Exit landscape
Climate tech exits have lagged. 2024-2025 saw:
- Form Energy: scale ramping, no exit yet
- Boston Metal: scale ramping
- Some early stage acquisitions
- Carbon Engineering acquired by Occidental Petroleum
- Multiple solar installer SPAC/IPO failures
The IPO window is closed for most climate tech through Q3 2026. Acquisitions remain primary exit path.
What developers should know
For climate-aligned venture-backed startups:
- Capital available but concentration in proven traction
- IPO unlikely until 2027+
- Strategic acquirer interest (oil majors, mining companies, utilities) growing
- Government grant + tax credit access becoming critical for capital efficiency
What to watch next
A major climate tech IPO success in 2026-2027 (likely Form Energy or H2 Green Steel) would reopen the public market window and unlock the next wave of climate capital. Until then, expect continued private market focus and gradual scaling of leaders.
