What Decarbonization Partners does

Decarbonization Partners is a private joint venture between BlackRock, the world's largest publicly traded asset manager, and Temasek, the Singapore sovereign wealth fund, established in April 2021 to deploy institutional capital into late-stage venture and early-stage growth equity opportunities that accelerate the transition to a lower-carbon economy. The firm operates as a thematic investment vehicle rather than a product company, sourcing, leading, and co-investing in funding rounds for climate- and decarbonization-focused businesses across multiple geographies.

Its disclosed portfolio spans seven lead or co-investment positions executed between mid-2024 and early 2026, with check sizes ranging from $31M (Guidewheel, AI-powered factory efficiency) to over $100M (EPG, modular AI data center infrastructure; osapiens, ESG compliance SaaS). Sector exposure includes AI data center infrastructure and cooling, industrial factory efficiency, residential electrification, ESG compliance software, energy transition analytics, and low-emission industrial materials such as carbon black and hydrogen. The firm typically leads rounds and syndicates with strategic and financial co-investors including Alibaba Cloud, Goldman Sachs Alternatives, MassMutual Ventures, Breakthrough Energy Ventures, Climate Investment, and Activate Capital.

As a private JV vehicle, Decarbonization Partners does not publish standalone financials or pricing terms; revenue is generated through standard fund management economics, primarily management fees on committed or deployed capital plus potential carried interest on realized exits. The operating team is small (11-50 employees) and concentrated in New York and Singapore, with disclosed leadership including Managing Director David Hayes. The firm has signaled global ambitions through investments across North America, Europe, East Asia, and Southeast Asia.

Direct peers

• TPG Rise Climate: TPG Rise Climate is a dedicated climate-focused private equity fund raising billions for late-stage growth and venture investments in decarbonization. It is the most direct competitor to Decarbonization Partners in the climate-focused growth equity category and is a frequent co-investor (e.g., with Decarbonization Partners in Monolith Materials).
• Breakthrough Energy Ventures: Bill Gates–backed early-to-growth stage venture fund investing in climate technologies across energy, industry, transportation, and buildings. It co-invested with Decarbonization Partners in Guidewheel's $31M Series B and operates in the same climate VC mandate.
• Generation Investment Management: Sustainability-focused long-only public and private investment firm co-founded by Al Gore. It deploys capital into climate solutions across public and private markets, making it a direct peer in the sustainable investment mandate space.
• Energy Impact Partners: A global investment platform backing innovative companies driving the energy transition, with a utility and corporate LP base. Comparable to Decarbonization Partners in climate-tech venture/growth equity and corporate-backed investment model.
• Climate Investment: Climate-focused investment firm backed by major oil & gas majors, deploying capital into decarbonization solutions. Co-invested with Decarbonization Partners in XNRGY Climate Systems and operates a directly comparable climate-transition mandate.
