With the UK committed to reaching net zero by 2050, the discussion will focus on rethinking the making and use of cement and diving into the industry-wide partnerships shaping the next generation of low-carbon cement. Currently, cement manufacturing accounts for seven-to-eight percent of global emissions and around one point five percent of all UK carbon emissions.

On the podcast launch, Lee Sleight, CEO of Holcim UK, said: “We are proud to bring this forward-thinking podcast to the airways. Across the industry we’re all having similar conversations around sustainability, the practicalities, the innovations, and the solutions. The Material Mix is a way to bring all these conversations together in a way that offers clarity and understanding. 

“We all need to be on the same page, contractors, manufacturers, executives and academics, if we are to move towards a net zero future. This podcast will get to the heart of challenges facing our industry today but also look ahead to 2050 and beyond.”

The Material Mix is available through Spotify and Apple, amongst other podcasting platforms. Subsequent episodes are planned and are set to be released later in the year.
