ESG at Ameresco

Founded on a mission to create value and provide energy efficient and renewable solutions to the organizations we serve, Ameresco is relentless in the pursuit of a sustainable future. Our ESG program’s theme of “Doing Well by Doing Good” reflects the inherent and grounded purpose behind the company’s success in delivering solutions that enable a low carbon future.

Since the very start, “doing good” has been part of the essence of our company – whether through the environmental impact of our independent energy solutions, our embrace of a diverse workforce with a deep bench of technical expertise, or engagement with our local communities with charitable activities – we have assembled a team of best-in-class industry leaders on our board of directors and senior management to execute on every level. Our President and CEO George Sakellaris, has paved the way for this exemplary initiative as a “founding father” of the energy efficiency industry.
