Today Barrett Steel, Morrow + Lorraine and Smulders join SteelZero, making a commitment to use, procure or specify 100% net zero steel by 2050.

28 October 2021, London – Three significant suppliers from the world of construction, architecture and engineering are joining SteelZero. By committing to use 100% net zero steel by 2050, they are signaling the growing demand for net zero steel. The announcement today highlights the increasing appetite from this sector to eliminating the carbon emissions associated with the built environment and renewable energy infrastructure.

Barrett Steel is the number one UK supplier in the steel stockholding industry, supplying construction, renewable energy and transport sectors, among others, with high quality steel products.  Morrow + Lorraine is a London based architectural practice that designs for a sustainable future. Based in Belgium, Poland and the UK, Smulders constructs and engineers steel structures for use in offshore wind farms, and other industrial markets.

They join twelve other SteelZero members, including Lendlease, William Hare and Ørsted, which are driving the decarbonization of the steel industry in the construction and property and renewable energy sectors. The SteelZero programme was launched in December 2020.

Steel fabricator William Hare joined SteelZero earlier this week (25 October) after heavily contributing to the SteelZero construction and property working group. Before joining, William Hare has been working with SteelZero members Grosvenor Britain & Ireland and Bourne Group to scope out the availability and use of low embodied carbon steel in a luxury development in Mayfair, London.

Mike Peirce, Director of Corporate Partnerships of the Climate Group, said: “By pledging to use 100% net zero steel by 2050, these companies are signaling to the market that demand is growing, and are bringing us one step closer to net zero steel being available for use in property developments and offshore wind farms.”

Guy Barrett, Group Purchasing Director of Barrett Steel said, “The Barrett Steel Group is committed to working in collaboration with SteelZero and its members to influence net zero steel globally. Combined with the responsible sourcing of steel, a soon to be launched Net Zero Carbon Roadmap demonstrates our objectives for cleaner, greener steel. As the UK’s largest steel stockholder and processor, our participation in this project will generate opportunities to share best practices to achieve the highest standards for sustainability.”

Stephanie Crombie, Head of Sustainability of Morrow + Lorraine said, “By joining SteelZero, Morrow + Lorraine is committing to specifying 100% net zero steel by 2050. The embodied carbon impact of steel needs to change in a fair and just way to ensure construction reaches net-zero and we’re excited to be a part of this global movement by the Climate Group and ResponsibleSteel. Morrow + Lorraine is therefore aiming to specify ResponsibleSteel™ Certified Steel on our projects moving forward. Our hope is to raise awareness of the SteelZero initiative and help to bring the transformation required to turn our industry from one that is carbon-hungry to one that is climate-positive.”

Raf Iemants, Managing Director of Smulders said, “Technological pioneering and local community engagement are part of Smulders’ business philosophy. Over the past years, this combination has evolved into a strong engagement towards carbon footprint reduction, not only focusing on our own emissions but also willing to involve our supply chain partners. Therefore, Smulders is proud to join the SteelZero initiative and consequently contributing to evolving carbon neutrality within the steel industry and offshore wind sector.”
