Sustainable revenue
- Achieve 50% of our gross revenue from sustainable products that are either low-carbon or circular.
Enabling and supporting KPIs
CO2 and energy
- 85% clinker incorporation in our cement.
- Alternative fuel rate in cement above 80%.
- Biomass fuel rate in cement above 35%.
- Measurement framework for scope 3 emissions embedded by 2025 and 10% reduction to 2030.
- 10% reduction in operational electrical kWh/t from a 2016 baseline.
- Net zero plans in all divisions developed to include targets for scope 1, 2 and 3.
Our Progress

| Our commitments | Our progress |
| Annual review of the cement carbon roadmap | The cement carbon roadmap was reviewed in 2025. Specific net CO₂ emissions were 429kg CO₂/tonne of cementitious material, against our 2030 target of below 400 kg CO₂ per tonne. |
| Padeswood CCS project to be operational by 2029 | In 2025, the Padeswood carbon capture and storage (CCS) project reached several major milestones, including being granted planning permission and agreeing funding with UK Government. These milestones enabled the Final Investment Decision and transition into the execution phase, with construction beginning on site. |
| Reduce Scope 1 CO₂ emissions by 15% from the 2016 baseline | Scope 1 emissions intensity reduced from 46.2kg CO₂/tonne in 2016 to 40.5kg CO₂/tonne in 2025 - a 12.3% reduction over the period. |
| Achieve 50% of gross revenue from sustainable products that are either low carbon or circular | The percentage of gross revenue from sustainable products in 2025 was: cement: 22% (low carbon); concrete: 78% (low carbon); aggregate: 0.8% (circular). Calcined clay was trialled as a supplementary cementitious material in ready-mixed concrete supplied from our Greenwich plant and incorporated into selected structural concrete pours, partially replacing Portland cement to reduce embodied carbon. |
| Embed a Scope 3 emissions measurement framework by 2025 and propose category-specific Scope 3 targets for 2030 | In 2025, we built on the foundations established in the previous year by consistently applying the same Scope 3 calculation methodology. This allowed us to identify and assess emissions across each Scope 3 category and further embed the measurement framework to inform future category-specific target setting. |
| 10% reduction in operational electrical energy consumption (kWh/t) from the 2016 baseline | Electrical energy consumption was 10.4kWh/t, down 11% from the 2016 baseline. |
| Every business line to develop an energy and carbon reduction plan using the 2016 baseline and aligned with a 15% reduction in Scope 1 emissions | Energy and carbon management is embedded across all business lines through ISO 50001-certified energy management systems, digital monitoring tools and lean improvement programmes. Targeted initiatives, including alternative fuels, fleet and equipment electrification, and process optimisation, are supporting energy and carbon reduction roadmaps aligned with the 2016 baseline and Scope 1 reduction targets. |
| 100% of company cars to be hybrid or electric and 50% of vans to be electric, by the end of 2030 | As at 31 December 2025, 98% of company cars were either fully electric or hybrid: 47% electric and 51% hybrid. The remaining diesel vehicles are due to be phased out by March 2027. As at 31 December 2025, 12% of van fleet were either fully electric or hybrid: 11% electric and 1% hybrid. |

Net zero in action
Construction to build UK’s first carbon capture facility at a cement works begins at Padeswood
We reached a FID (Final Investment Decision) with UK Government to build the UK’s first carbon capture facility at a cement works at our Padeswood site in September. The announcement followed planning permission being granted by Planning and Environment Decisions Wales earlier in the year. Subsequently an EPCM contract was signed to allow construction to move to the next phase.
The UK’s first carbon capture and storage (CCS) facility will be built at the existing Padeswood cement works site in north Wales.
First trials of CarbonCure in ready-mixed concrete
The first trials in England using CarbonCure technology in ready-mixed concrete were carried out at our Greenwich plant. The process involves injecting pure manufactured CO2 into fresh concrete, where it becomes permanently mineralised. It has the potential to reduce the CO2 associated with concrete while maintaining performance.
Our Greenwich plant also completed its first calcined clay trials, which demonstrated the supplementary cementitious material can be used alongside evoBuild low-carbon GGBS and limestone powder to provide customers with lower carbon concrete options.
UK-first hydrogen fuel-switching asphalt trial continues
We continued our UK-first trial to use hydrogen as a fuel to decarbonise asphalt production at our Criggion plant in mid-Wales. It aims to demonstrate that hydrogen is a viable alternative to fossil fuels in reducing the carbon footprint of asphalt.
evoZero arrives in the UK
The first shipment of evoZero carbon captured near-zero cement arrived in the UK from our Brevik plant in Norway for use in construction projects across the country. evoZero was also named Product of the Year at the 2025 Highways Awards.
The UK’s first tanker of evoZero cement is collected from the Port of Goole in East Riding, Yorkshire. The UK’s first carbon capture and storage (CCS) facility will be built at the existing Padeswood cement works site in north Wales.
