Civil engineers have an important role to play in the fight to tackle climate change. The ICE’s Decarbonisation Community Advisory Board (CAB) is helping to place the decarbonisation of our industry at the heart of the Institution’s agenda through a range of activities.

Earlier this year, the Decarbonisation CAB developed an internal Decarbonisation Strategy for the ICE, which outlines key priorities and activities, both ongoing and future, that demonstrate the Institution’s commitment to helping members achieve carbon reductions.

During this session the audience will hear from Lewis Barlow, co-chair of the Decarbonisation CAB, who will give an overview of the strategy, and then shine a spotlight on two of the key elements: procurement and carbon champions.

The audience will hear from CAB member Stacey Collins about recent decarbonisation developments in the procurement space, such as the NEC’s secondary Option X29 Climate Change for all NEC4 main and main subcontract forms, and the inclusion of a Procurement clause in the new PAS 2080:2023.

This event will also celebrate two Carbon Champions who have recently been awarded the status, who will showcase how they managed to make significant carbon savings compared to the norm in their own projects.
