FRAMINGHAM, MASS.—Ameresco, Inc., a leading energy infrastructure solutions provider, announced the release of its 2025 Impact Report centered on the theme of “25 Years of Impact.” The report details fiscal year 2025 performance and progress across Ameresco’s three impact pillars—People, Planet, and Policy—underpinned by a quarter century of delivering solutions that reduce energy costs, strengthen resilience, and create lasting value.
“Since 2000, Ameresco has operated on the belief that sustainability, resilience, and sound financial decision-making are fundamentally connected,” said George Sakellaris, Chairman of the Board and CEO of Ameresco. “Our twenty-fifth year in business reflected that conviction, backed by a best-in-class team who deliver long-term value to our customers. I am proud of the impact we continue to make and excited by the scale of what’s ahead in energizing a sustainable world.”
Key highlights from the 2025 Impact Report include:
- People: People are the foundation of Ameresco’s success, and central to the company’s 25 years of impact. Through the One Ameresco culture, the company fosters creativity and collaboration across a global team, invests in mentorship, training, safety, and employee satisfaction, and extends its C.A.R.I.N.G. values into the communities it serves.
- Planet: Ameresco’s track record is defined by helping customers navigate real-world energy challenges: reducing consumption, improving resilience, and lowering emissions at scale. Approximately 18 million metric tons of carbon dioxide equivalent were avoided during 2025 from Ameresco’s owned energy assets and customer projects. The company continues to advance its customers’ climate action journeys and measure its own carbon footprint amid an increasingly complex energy landscape.
- Policy: Good governance is essential to Ameresco’s sustainable growth and 25-year track record of execution. From Board oversight and risk management to cybersecurity, compliance, and responsible public policy engagement in a dynamic regulatory environment, its practices are built on transparency, accountability, and the highest ethical standards.
“Impact is about whether what we build matters over time: helping customers lower energy use, improve reliability, and meet their goals in a way that lasts,” said Mark Chiplock, Executive Vice President, Chief Financial Officer, and Executive Chair of Ameresco’s Ambassadors of Impact. “This year’s Impact Report reflects on our continued commitment to responsible growth, measurable progress, and strong governance as the global energy transition accelerates.”
