A recent cabinet report said: "Ameresco will contribute substantial investment, capacity and expertise to support the desired step change in the pace of delivery of low carbon projects. City Leap projects will have a positive impact for Bristol's businesses and residents, providing homes and businesses with fairly priced clean energy." The City Leap deal was first approved by the cabinet in April 2019, and after a long search, the council chose American company Ameresco and Swedish company Vattenfall to head up the project.
