About This Fund
CarbonCount Holdings 1 LLC (CCH1) is a sustainable infrastructure investment platform established as a joint venture between KKR, a leading global investment firm, and Hannon Armstrong Sustainable Infrastructure Capital (HASI), a specialist clean energy investor and publicly listed REIT. The platform commits up to $2 billion in aggregate — $1 billion each from KKR and HASI — to invest in climate-positive clean energy and sustainable infrastructure assets across the United States. HASI serves as the primary investment manager, deal sourcer, and operational steward of the portfolio, while KKR provides co-investment capital and balance-sheet capacity.
CCH1 deploys capital across sustainable infrastructure asset classes consistent with HASI's established investment strategy, including behind-the-meter energy systems, grid-connected renewable energy installations, renewable natural gas infrastructure, and sustainable transportation projects. The platform employs HASI's proprietary CarbonCount scoring methodology to measure avoided carbon dioxide equivalent (CO2e) emissions for each investment, providing investors with a transparent, standardized climate impact metric alongside financial returns. To expand its financing capacity, CCH1 issued $592 million in senior unsecured notes through a private offering, reflecting institutional demand for high-quality sustainable infrastructure debt.
The KKR-HASI partnership represents a convergence of institutional private equity expertise and deep sector specialization in the U.S. clean energy transition. HASI, the platform's primary investment manager, manages a portfolio of more than $13 billion in climate-positive assets and has deployed capital across solar, wind, energy efficiency, and climate resilience projects for over two decades. CCH1 is an early example of the scaled bilateral platforms increasingly used by institutional investors to access the growing pipeline of U.S. sustainable infrastructure opportunities without the constraints of traditional commingled fund structures.
