In 2025, Ara's Private Equity and Infrastructure portfolio enabled an estimated two million metric tonnes of CO2e reduction and 912.5 thousand metric tonnes of waste mitigation, equivalent to removing 464.1 thousand passenger vehicles from the road for one year and the waste handled by 130.1 thousand garbage trucks, respectively.
"2025 made clear that low-carbon solutions must compete on an economic basis in order to scale," said Charles Cherington, Managing Partner at Ara Partners. "We back businesses that compete head-to-head with emissions-intensive incumbents on cost, quality, and reliability. Macro tailwinds are accelerating demand for resource efficiency and onshoring of key supply chains - exactly where our portfolio is positioned."
This year's report is the firm's most comprehensive to date, reflecting significant platform growth following the final close of Ara Infrastructure Fund I in 2025 and the continued build out of its Energy strategy. Ara sits at the center of the energy and industrial transition, with $7.7 billion in AUM and 27 portfolio companies across its three strategies.
"In a time of changing energy market fundamentals, decarbonization delivers what industrial customers and investors need most; lower operating costs, supply chain security, and stronger competitive positioning," said Irina Markina, Chief Decarbonization Officer at Ara Partners. "Across our portfolio, we increasingly see emissions and waste reduction as core levers to meet these priorities."
The report details Ara's Decarbonization Value Creation framework, highlighting hands-on support through the firm's Decarbonization, Ara Project Execution and Operations (APEX), and Government Affairs functions. Portfolio company spotlights of Blue Whale Materials, Continuum, Cycle0, Microtec, and Sedron Technologies demonstrate how decarbonization is enabling measurable financial outcomes while accelerating the transition to a low-carbon economy.
"Industrial decarbonization is a long-term, generational investment opportunity, and Ara is built for it" said Troy Thacker, Managing Partner, "That has been our thesis from the outset, and it continues to be our guiding principle."
