Commonwealth Engineers' Council (CEC)
The Commonwealth Engineers' Council is a global network whose aim is to advance the science, art and practice of engineering for the benefit of humankind.
Lewis Barlow, decarbonisation head of profession at WSP UK, will highlight the critical role of PAS 2080: Carbon Management in Buildings and Infrastructure in driving global decarbonisation efforts. As the world grapples with the urgent need to mitigate climate change, PAS 2080 provides a robust framework for managing carbon across the entire infrastructure value chain. This talk will explore how PAS 2080 facilitates the reduction of carbon emissions through a systematic approach that integrates carbon management into infrastructure planning, design, construction, and operation.
Lewis will share insights on the international uptake of PAS 2080, highlighting successful implementations of the approach in the UK, Sweden, and Australia. These examples will demonstrate how the whole life carbon management process has enabled these countries to make significant strides towards their national net zero targets. The presentation will also address the challenges and opportunities associated with implementing PAS 2080 in different regions, emphasising the importance of collaboration among stakeholders.
Lewis will also outline the broader initiatives of the Institution of Civil Engineers (ICE) and industry best practices for decarbonisation. He will provide an overview of the ICE's efforts to promote sustainable infrastructure development and the role of civil engineers in leading the transition to a low-carbon future. Attendees will gain valuable knowledge on how to leverage PAS 2080 to achieve meaningful emissions reductions and support sustainable economic growth.
This talk is particularly relevant for civil engineers, policymakers, and industry leaders who are committed to advancing decarbonisation in the built environment. By the end of the session, participants will have a deeper understanding of PAS 2080 and its potential to transform the future of civil and infrastructure engineering.
This event is organised in partnership with the Commonwealth Engineers’ Council.

WSP UK and ICE
head of profession for decarbonisation / trustee for carbon and climate
Lewis Barlow FICE CEng CEnv CWEM is the ICE’s trustee for carbon and climate and head of profession for decarbonisation at WSP UK. He is also a Visiting Professor in the Department of Civil and Environmental Engineering at the University of Strathclyde.
With over 25 years of experience, Lewis advises governments, local authorities and developers on whole-life carbon management and infrastructure decarbonisation. He contributed to PAS 2080: Carbon Management in Buildings and Infrastructure, steers the ICE’s Carbon Management Plan, and champions the upcoming PAS 3090 on adaptation pathways for infrastructure systems.
Lewis set up and co-chairs the ICE’s new Carbon and Climate Advisory Group, which brings carbon, climate resilience and nature together in infrastructure decisions.
A regular guest lecturer and ICE tutor, Lewis authored the ICE’s Carbon Management in Infrastructure and Carbon in Infrastructure Procurement courses. His work includes a secondment to the Scottish Government on its £5 billion City and Regional Growth Deals programme.

Technical Curiosity is a key pillar of building a successful career, and Pablo Gugel, director of sustainability and AI at Bryden Wood, will present and lead a discussion on Technical Curiosity: Broadening your perspective.
