Sustainability
Aspiring to achieve zero harm – to our people, our environment and the communities in which we work – is a fundamental driver of our business and why Delta Group invests heavily in maintaining our social licence to operate and to ensuring the work we undertake has a lasting local, social and environmental legacy.
