Large businesses like ours have an important contribution to make in cutting global GHG emissions and reducing the risk of climate change. Our climate change position statement is available on our website and sets out our commitment to reducing GHGs. We have made significant reductions in our carbon emissions since our 2014 baseline year.

Scope 3 Emissions
During 2023, we carried out a complete global scope 3 assessment to establish a full GHG baseline for our 2022 scope 3 emissions, for the first time. This involved the calculation of ten out of the 15 scope 3 categories with a particular focus on upstream emission categories. The remaining five were excluded on the basis that they were either not applicable or not required. We were able to source a significant amount of consumption data, which allowed a process-based approach to be taken for most of the scope 3 categories. This provided greater accuracy than a spend-based approach, which limits insights on actual supply chain performance.
For our 2022 reporting period, our combined GHG emissions were 2,497,579 tCO2e. Scope 3 emissions accounted for 96.7%, scope 1 for 1.8% and scope 2 for 1.6% of this number. Going forward, as a result of these efforts, we now have a robust GHG emissions baseline, from which to develop a decarbonization pathway.
2023 Performance
In 2023, 12 of our 13 manufacturing facilities procured 100% renewable electricity. The outlier facility is located on an industrial complex which does not offer renewable electricity contracts. Renewable energy accounts for 19% of our total energy mix.

Resource Reduction Group
Established in 2016, our Global Resource Reduction Group (RRG) was set up to develop and share best practice across our 13 manufacturing sites. Its global remit encompasses large capital investments, company-wide projects, and local initiatives. We have a dedicated energy reduction fund to support major projects where the payback period is longer than normal.
The group, which meets up to three times a year, continued to deliver and maintain a pipeline of energy reduction projects in 2023. Going forward, these activities are forecast to reduce our annual energy consumption by over 2,161 MWh and our total group scope 1 and 2 emissions by 98 metric tonnes CO2 equivalent.
Reducing Our Emissions
Activities introduced in 2023 to further improve our energy efficiency and reduce our GHG emissions included:
- St Mihiel, France
- Vernon, France
- Leuna, Germany
- Castiglione, Italy

St Mihiel, France
The upgrading of three GRP tanks at our St Mihiel site, with more efficient, greater insulated stainless steel tanks, will provide annual savings of 420 MWh of gas. Additionally, the site optimized its procedures by recovering heat from waste steam condensate and repurposing it to preheat the makeup water for boilers. This is expected to save 250 MWh of gas annually.

Vernon, France
The full renovation of the admin building roof and installation of improved insulation at our Vernon site will save 20,164 kWh of gas per year.

Leuna, Germany
Our Leuna site upgraded its production building lighting system with LED replacements resulting in an annual saving of 21,810 kWh of electricity.

Castigliogne, Italy
To reduce gas consumption at our Castiglione site, the aging boiler gas burners were replaced with more efficient units saving 2,424 MWh of gas annually. To further reduce emissions, the site crane was replaced with an electric vehicle and the replacement of existing air compressors, with an improved set up, led to enhanced optimization and reduced consumption, saving 36,000 kWh of electricity annually.
- Barcelona, Spain
- Oklahoma, USA
- Salisbury, NC, USA
- Ellesmere Port, UK

Barcelona, Spain
The replacement and upgrade to the aging insulation in the steam and condensate system at our Barcelona site will provide savings of 514 MWh of gas annually. The replacement of a cooling water pump with a more efficient unit is expected to save 61,826 kWh of electricity annually.

Oklahoma, US
Our Oklahoma, US site continued its program of enhancing the efficiency of the lighting on site by installing LED lighting in the warehouse and office, which is expected to save 41,007 kWh of electricity each year.

Salisbury, NC, USA
The site installed a new flaker return water precooling system, helping to reduce the energy needed to cool water on a key solid surfactant processing line and providing electricity savings of 89,647 kWh per year.
