PPN 06/21 carbon reduction plan

Heidelberg Materials UK is committed to playing its part in creating a sustainable future and, despite a challenging backdrop, we have continued to make good progress. 

We have reduced our CO₂ emissions in the UK by over 50 per cent since 1990 and were the first company in our industry to achieve the ISO 50001 standard for all our UK operations. We are proud of the progress we have made and, looking to the future, we are excited by the innovative approaches we are championing as we move towards our net zero goal. 

In 2022 Heidelberg Materials Group set out a series of new targets to accelerate our journey to net zero by 2050. By 2030, we aim to:

• Cut CO₂ emissions to 400kg per tonne of cementitious products.
• Generate 50% of gross revenue from low-carbon and circular products and solutions.
• Offer circular alternatives for half of our concrete products.

We have taken a series of important steps to help make our vision a reality. In September 2025 a final investment decision was reached with the UK Government, allowing us to move forward with our plants to build a carbon capture facility at our Padeswood cement works in north Wales. It is a UK first and will enable us to produce evoZero carbon captured near-zero cement in 2029, which will help the construction industry reach its decarbonisation aims.

We also successfully completed a hydrogen demonstration project at our Criggion asphalt plant, paving the way for the UK’s first hydrogen-powered production facility, as well as the introduction and continuation of other projects, some of which are included later in this report.

We know that the long-term success of our business relies on sustainable practices. Our sustainability department supports the individual business lines in their carbon reduction efforts and includes a dedicated carbon innovation manager to ensure that continuous CO₂ emission reductions are achieved. The team is supporting the executive team to deliver on our ambition, ensuring we operate in accordance with PAS 2080 – the carbon management standard for buildings and infrastructure, which we obtained in 2023 – and continue to lead the industry in building a sustainable future.
