INTENSITY RATIO
The intensity ratio is total gross emissions in metric tonnes
separately for ‘mandatory’ emissions and ‘mandatory & voluntary’ emissions for the UK and regionally for the North West, West and North East SigmaRoc Regions. This financial metric is considered the most relevant to the Company’s wide- ranging activities and allows a comparison of performance across other organisations and sectors.
ENERGY EFFICIENCY ACTION DURING CURRENT FINANCIAL YEAR
has continued to experiment with low temperature asphalt by switching to Nytherm during the reporting period to reduce gas oil usage by approximately 55,500 litres. Furthermore, the addition of 3 EV’s to the company fleet (including 2 plug- in hybrids) will reduce diesel and petrol consumption and therefore reduce emissions associated with transport. At Carrières du Hainaut, there was an extension of the existing photovoltaic park by increasing the existing surface area by approximately 57%. This installation aims to send 62% of the electricity generated to the Carrières site for self- consumption, with the surplus sent into the ORES public network. The project includes the installation of a total power of 1,999,215 kWp from a total of 2,889 panels. Gross UK emissions have decreased by 7.0 % (1,075 tCO2e) in 2023. This is largely due to the significant reduction in emissions by company owned vehicles and site fuel (1,112 tCO e) across

Emissions in the North East have seen a 7.5% (51,005 tCO e) 2
decrease in 2023 compared to 2022. A large share of this decrease is due to the further transition away from coal to alternative fuel sources such as recycled fuel oil and biomass.

Bolton Hill Quarry decreased by 1.78 GWh (442.3 tCO2e) in 2023, contributing to nearly half of the decrease in company vehicle and site fuel emissions.
