Introducing the Roadmap to Net-Zero Carbon

For the past two years Concrete NZ have been developing their “Roadmap to Net-Zero Carbon for Aotearoa New Zealand’s Concrete Industry”. This journey will form the basis of Ralf’s presentation. Building on past and current initiatives, the map covers both ready-mixed concrete and concrete products to involve all of the major parties in the value chain, including manufacturers, producers, designers and constructors. The Roadmap aims to reduce the Concrete Industry’s greenhouse gas emissions to net-zero by 2050, in line with the Climate Change Response (Zero Carbon) Amendment Act 2019. It builds on global concrete industry efforts towards net zero carbon  emissions. The Roadmap was funded by Concrete NZ, MBIE’s Building Innovation Partnership, and BRANZ through the Building Research Levy, and was launched in August 2023.
