The fourth episode of our Building Talks Net Pero podcast series has a selection of interviews recorded in Glasgow during the COP26 climate conference.

This week Building’s reporter Tom Lowe speaks to construction attendees in the ‘Green Zone’ of COP26 for the Cities, Regions & Built Environment Day, including Gregor Craig, Skanska UK chief executive, and Hannah Vickers, Mace’s chief of staff.  

Craig explains how attending COP26 and meeting so many people striving for net zero in construction has left him optimistic that companies can find mechanisms to collaborate and solutions that will have an impact at scale.

Vickers, who is also on the Construction Leadership Council steering group, talks about how construction will need to work closely with the energy sector. She also goes into detail about Mace’s own corporate strategy to reduce emissions, such as zero diesel construction sites, and how the biggest impact for the sectors’ overall carbon footprint is going to be through reducing clients’ emissions.

We also hear from Alastair Mant, director of business transformation at the UKGBC, about its launch of the Whole Life Carbon Roadmap
