Cala Sustain provided strategic environmental management support at the active Airbus site in Bristol. This involved specific site risk management, development of the European environmental management systems, regulatory compliance and overseeing prescribed legal processes. The Filton site in Bristol that includes a former airfield is a large industrial location with a workforce of approx. 5000 people. The site has been subject to heavy industry for over 100 years and careful management of complex legacy issues was as vital as current environmental regulatory and systems management.
