Sustainability

Supporting our Members to meet new ambitions on Sustainability is now one of our primary focuses.

Just as we've been instrumental in shaping standards for offshore Safety over more than 50 years, we recognise the pivotal role we can play in bringing our Members and the industry together to address new Sustainability demands from clients, colleagues, and society at large.

Our Members are central to driving the transition towards a more sustainable offshore energy seascape – an essential step towards meeting ambitious targets for a Net Zero future. At IMCA, we stand ready with unwavering support to our Members as they navigate this transformative journey.
