These are emissions from our buildings and production sites. 2020 was the first year we measured performance against our science-based targets, and we are well on way to achieving a 59% reduction by 2030. As part of our Net Zero roadmap we have identified 21 projects in which we are investing significantly over the next 8 years to progressively reduce emissions across our UK and Irish sites.
From 2018, reduce Scope 1 and 2 absolute emissions by 59% by 2030 and to Net Zero by 2050
Since 2020, we have procured 100% renewable electricity to power our sites, reducing about 51% of our baseline operational emissions to zero. At present, we purchase certified Renewable Energy from our providers. With the demand for renewable electricity increasing rapidly, we are exploring options to secure future supplies by investing in renewable energy generation.
F-gases which are used in refrigeration systems are very potent Greenhouse Gases and account for about 15% of our baseline emissions. We have progressively reduced fugitive emissions from our sites over the last 5 years, and we target to replace these systems with net zero emission, ammonia refrigeration systems by 2035.
Burning fossil fuels to heat water on our sites accounted for approximately 33% of our baseline operational emissions. Over the last few years, we have been switching to lower emission fuels such as Liquefied Petroleum Gas (LPG). We will reduce these emissions rapidly by 2035, through a range of measures, including using renewable electrical heat sources and updating equipment to burn lower emission and carbon neutral fuels such as BioLPG. We will install renewable sources of heat recovery such as air to water heat pumps, beginning with our Llanybydder site in Wales.
Fuelling our own vehicles accounted for about 1% of our baseline emissions, and we plan to switch 100% of the company car fleet to zero-emission vehicles by 2030.
Heat Recovery System
at Treburley, England
Following the rollout of a centralised CO₂ refrigeration system, a heat recovery system was installed to capture and reuse waste heat for hot water production, reducing reliance on gas-fired boilers.
The system has been operating consistently since September 2025 and on current operations, it is expected to recover approximately 289,812 kWh in 2026, reducing gas usage by 49%.
Air Compressor Upgrade
at Sawley, England
An energy efficiency upgrade was implemented by replacing a higher-energy-use air compressor with a more efficient alternative, improving overall system performance.
This reduced average weekly energy consumption from 6,920 kWh to 5,850 kWh, delivering annual savings of approximately 55,640 kWh.
Refrigeration System Upgrade
At Kildare, Ireland
The site upgraded its low-temperature refrigeration system to a more efficient ammonia-based solution, replacing the previous F-gas system and improving overall performance.
This transition reduces reliance on F-gases, which are one thousand times more potent than carbon dioxide, meaning even small emissions can have a substantial environmental impact. The upgrade is expected to achieve energy savings of 155,264 kWh per year in cold storage and 1,400,241 kWh per year in blast freezing, equivalent to a total saving of 369 tCO₂e annually.
Vacuum Pump Variable Speed Drives
At Charleville, Ireland
Variable speed drives were installed on vacuum pumps used for sealing packaging to better match energy use with demand.
This reduced electricity consumption by 44%, improving efficiency and lowering operational emissions.
