On the first episode of the brand new First Site podcast by Construction News, we dive into one of the biggest challenges facing the sector – decarbonising steel and concrete. Together, these materials account for 14% of global carbon emissions, a huge contributor to such a huge challenge for the construction industry. Joining editor of Construction News Colin Marrs for this inaugural episode are Ian Riley, chief executive of the World Cement Association, and Dr. Michael Sansom, sustainability manager at the British Constructional Steel Work Association. First Site is a new podcast by Construction News, in partnership with Speedy Hire. Each month we talk to industry experts about the hot topics in construction.
