Carbon Trust

Calor is proud to have the Carbon Trust Standard for reducing carbon emissions, which recognises our commitment and efforts to minimise our carbon footprint. In order to achieve the standard, the Carbon Trust assesses our performance in three key areas: carbon footprint measurement, carbon management and carbon reduction performance. Calor has to be re-assessed every two years in order to maintain the certification. 

Sustainability memberships

Calor is a member of numerous sustainability organisations. We do this so that we can learn from others’ best practice ideas as well as push the sustainability agenda with government and other authorities as part of an industry wide collaborative group.

Corporate sustainability policies

Calor adheres to a range of policies and guidance statements that are designed to ensure we operate responsibly. We do this by setting a framework in our annual objectives, our actions and decision making.
