Our Carbon and Sustainability Statement

The current intense media interest in environmental issues and carbon targets has shone a piercing green light on business and its sustainability practices.

And as buyers, investors, and communities look ever more determinedly for strong ESG (Environmental, Social, Governance) credentials in the businesses they deal with, Clark-Drain is proud to be able to say that we have had a concerted programme of carbon reduction and sustainability improvement in place since 2018, with many targets already achieved.
