Environmental

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. Sustainability has always been at the forefront of our business — from our energy saving customer projects and clean energy generation assets, to workplace green initiatives and giving back to our communities.

The world is facing climate change and biodiversity loss at levels that threaten the life supporting systems of our planet for future generations. The scientific consensus is that human activity is the cause. Ameresco takes our responsibility of protecting the environment seriously. Our business is founded on providing clean, green, and sustainable solutions that reduce greenhouse gas emissions for our customers.

Ameresco is committed to continuing to deliver comprehensive projects that help accelerate the global transition to a net zero carbon future. We are also committed to reviewing our own carbon footprint, publishing data on emissions, and preparing plans to achieve net zero carbon from our direct operations.

Environmental Goals

  • Increase cumulative carbon offset by at least 15 million metric tons with owned assets and customer projects by end of 2021.
  • Determine our operating impact baseline and define offset strategy plan in the pursuit of net zero.
  • Launch corporate “Green Week” with lessons and activities focused on reducing environmental impact in the office.
  • Appoint corporate-led “Sustainability Team” to identify, implement, and govern green initiatives in all our offices and operations.
  • Measure transportation carbon footprint and define strategy for offset plan.

Ameresco’s Environmental Impact

In 2020, Ameresco’s renewable energy assets and customer projects delivered a carbon offset equivalent to approximately 12.6 million metric tons of carbon dioxide, and over 60 million cumulative metric tons since going public in 2010. This carbon offset is approximately equal to one of the following:

Ameresco in Action

Green Week 2021

Ameresco’s first annual Green Week celebrated the variety of ways that our team can energize a sustainable future and occurred companywide in April 2021. Each day focused on a different topic to educate, inspire and empower employees around sustainability and climate action. The intent of the week was to explore and ignite ideas of what each Ameresco team member can do to create change in our own homes, workspaces, and communities.
