Square Gain - environmental services and training

About us

Square Gain was established in 2015 with a mission to accelerate the journey to a low carbon, sustainable and resilient economy. We do this by helping clients to improve their Environmental, Social and Governance (ESG) performance and climate resilience.

We believe in equality and inclusion and to be 'fair and square'. We also want clients to gain an advantage through an inclusive ESG approach. Hence the name Square Gain.

Experience is the key to success. All our staff and associates have over 20 years sustainability leadership experience. We provide clients with the practical knowledge and expertise that this brings and have worked with over 60 clients, from small companies to multinationals, from universities and councils to the NHS.

We focus on supporting our clients develop in-house skills by embedding ourselves with client teams, and by providing training and e-learning to build capacity and make real progress on carbon reduction, circular economy and wider sustainability.
