Aggregate Industries

Area of expertise: carbon management

Business case

The first step in the company-wide programme was to prioritise the division with the highest energy intensity within Aggregate Industries.

The asphalt operations were targeted to deliver quick wins to make a significant impact on the overall carbon footprint. Implementation of the identified projects across all of the asphalt sites would deliver annual cost savings of £3.7m for an estimated capital expenditure of £8.5m.

The projects are being piloted and will be rolled out across the UK asphalt division over the next three years to ensure the minimum business disruption.

Carbon emissions impact

The impact of these projects on the overall Aggregate Industries UK KPI would be a 26% reduction from the baseline figure of 9.38kgCO2/tonne to 6.93kgCO2/tonne.

Aggregate Industries is continuing to improve the accuracy of data collection which will enable the development of devolved targets for each business unit and region.

The next stage of the carbon management programme is to investigate further reduction opportunities in other areas of the business beyond the asphalt division including primary aggregates and concrete building products.

Statistics:

• £3.7m Identified annual cost savings
• 26% carbon reduction from the baseline figure
