O鈥橰ourke said all its concrete on UK jobs will now be low carbon

The country鈥檚 biggest private contractor said the changes were being introduced following a long-term research programme co-funded by O鈥橰ourke and government research group Innovate UK.

O鈥橰ourke said the research, carried out in collaboration with the University of Cambridge and Sheffield University鈥檚 Advanced Manufacturing Research Centre, 鈥渉as proven that a range of low carbon concrete options can be successfully deployed on projects as a like-for-like substitute for traditional concrete鈥.

O鈥橰ourke said the overall carbon reduction will be 28% when compared with the company鈥檚 concrete usage last year.

The firm鈥檚 newly appointed chief operating officer Cathal O鈥橰ourke, who took up the post last week, said: 鈥淭he built environment makes a significant contribution to global warming and constructors must work with clients and design partners to deploy new technologies and innovations that make modern methods the norm and enable us to build in less carbon intensive ways.鈥

The firm, which last year became a founding member of Concrete Zero, said that 43% of the concrete products it manufactured in 2022 were low carbon.
