Energy performance in 2025
Our Scope 1 and Scope 2 GHG emissions come from our manufacturing operations and represent the part of our footprint that we can directly influence by changing the way we use energy in our facilities.
Scope 1 GHG emissions (tCO2e.) from stationary fuel combustion were 106,088 tonnes and Scope 1 GHG emissions (tCO2e.) from process and mobile emissions were 5,976 tonnes (of which process emissions were 5,655 tonnes). For 2025, total Scope 1 GHG emissions (tCO2e.) were 112,064 tonnes, which is a 0.9% increase over 2024 values and 45.5% decrease over 2015 values.
Market-based Scope 2 GHG emissions (tCO2e)1 were 33,072 tonnes, which is a 21% decrease over 2024 values and 76% decrease over 2015 values.
1 The Scope 2 emissions figure was calculated using the market-based methodology. The location-based figure for the same period is 144,130 tCO2e.
We continue to improve the efficiency of our gas-fired kilns whilst actively assessing the feasibility of green technology options for our material portfolio. For further information on our path to net zero, please see page 38 of our 2025 Annual Report.
