Despite constrained overall private capital fundraising, leading buyout firms are securing substantial investments for climate strategies, highlighting a growing bifurcation in the market between large established funds and smaller emerging managers.
Even as fundraising for private capital remains constrained, major buyout houses are still attracting substantial commitments for strategies aimed at the climate transition.
According to ImpactAlpha, more than two dozen sovereign wealth funds, pension schemes and other institutional limited partners have backed climate-focused vehicles run by firms including TPG, Brookfield, Apollo and KKR.
San Francisco–based TPG has been particularly active. Its impact platform, TPG Rise, has continued to expand: TPG Rise Climate had secured in excess of $6.5 billion of commitments for a second climate-focused vehicle as of September 2025, ImpactAlpha reports. The United Arab Emirates’ ALTÉRRA anchored the effort with a multihundred‑million‑dollar commitment that, together with other capital, has helped finance both the Rise Climate follow‑on and a separate Global South Initiative. According to TPG, that initiative locked in $1.25 billion of initial capital in September 2024 and seeks to accelerate investments across clean energy, sustainable materials and carbon removal opportunities in emerging markets. TPG also disclosed a $1.5 billion strategic partnership with Hassana Investment Company of Saudi Arabia to support Rise Climate, and said ALTÉRRA committed $1.5 billion across its Rise platform in late 2023, part of which was allocated to the Global South work. The firm has additionally raised around $1.3 billion for a first Rise Climate Transition Infrastructure fund, which targets a $6 billion hard cap. TPG’s broader Rise impact business includes TPG NEXT, a 2021 initiative seeded by a $500 million CalPERS anchor; that follow‑on has raised only modest additional capital from a limited group of investors, the firm says.
Brookfield Asset Management has also marshalled vast pools of capital for decarbonisation strategies. The company announced a final institutional close of $20 billion for its Global Transition Fund II in October 2025, with ALTÉRRA providing $2 billion and Norway’s Norges Bank Investment Management a $1.5 billion commitment, Brookfield said. The fund aims to scale clean energy and other decarbonisation solutions globally, and complements earlier Brookfield efforts to deploy catalytic capital into emerging markets, where an initial close of $2.4 billion for a Catalytic Transition Fund was recorded in September 2024.
Apollo’s environmental and social private equity strategy has attracted more modest backing by comparison. Its Impact Mission Fund closed on roughly $1 billion in 2023, with a mix of institutional investors among its LPs, according to PitchBook and the fund’s disclosures. Apollo has also benefited from allocations tied to the U.S. Greenhouse Gas Reduction Fund, participating in capital deployments to support distributed energy and storage projects.
KKR launched a Global Climate Transition Fund in 2023 and had amassed just over $3 billion by late 2025 toward a $7 billion target. Institutional supporters include BBVA and Singapore’s Temasek, and KKR has been active in deploying capital into battery storage and renewable projects, such as a recent investment supporting Australian wind and storage developer HMC Capital.
The investor base for these flagship climate vehicles spans national wealth funds, large pension pools and municipal plans. ImpactAlpha’s reporting highlights participation by organisations including ALTÉRRA, Hassana Investment Company, Norges Bank Investment Management, GIC, Temasek, Canada’s Caisse de dépôt et placement du Québec, Los Angeles City Employees’ Retirement System, Michigan’s department of treasury and the New York City Board of Education Retirement System.
Industry participants say the appeal of such strategies lies in combining scale, operational expertise and the prospect of long‑dated cashflows tied to energy transition assets. At the same time, some of the record or near‑record closes reflect anchor commitments from a handful of very large institutional investors rather than a broadening of the LP base. TPG’s disclosure that its NEXT programme has struggled to attract widespread follow‑on capital is one example of how fundraising momentum for smaller impact managers remains uneven even as mega‑funds continue to close.
Taken together, these raises underscore a bifurcated market: large managers with established climate platforms and deep client relationships are still able to secure multibillion‑dollar commitments, while newer or smaller strategies face a tougher fundraising backdrop. The flows also illustrate how public and quasi‑public climate vehicles such as ALTÉRRA are increasingly steering significant pools of capital into private funds that can deploy at scale across both developed and emerging markets.
