Since we started monitoring our energy use and emissions against our 2006 baseline year, our energy and carbon reduction has been significant. In 2019, we delivered a range of activities and investments to further increase our energy efficiency and reduce our greenhouse gas emissions (GHG).

2020 Performance

In 2020, following a change in methodology, we reduced our absolute Scope 1 and 2 GHG emissions by 46% since 2019 and 53% since 2006. Our GHG emissions intensity* decreased by 36% since 2019 and 50% since 2006.

Although a number of our facilities reduced their absolute energy consumption in 2020, the overall reduction in production volume was greater. Our production plants aim to use energy as efficiently as possible; however, they do need a minimum amount of energy to operate. Where production volumes fall below optimum levels, this has an adverse impact on consumption and thereby emissions data. For 2020, this resulted in a 21% increase in the energy use per tonne of product produced since 2019, however a saving of 4% has still been achieved versus the 2006 base year. and a lower decrease, when compared to previous reporting years, of 4% since 2006.

Case Studies

Energy Reduction Group

Our global Energy Reduction Group (ERG) was established in 2016 following recognition that the majority of obvious improvements had been achieved. The Group, led by Corporate Engineering, is responsible for the identification and evaluation of capital investment projects where the payback period is longer than would normally be required. A dedicated Energy Reduction Fund is allocated every year for such projects.

The fund targets projects that could help deliver our 2019 to 2020 objective of achieving a 2% (1,104 metric tonnes) reduction in our Scope 1 and 2 emissions, based on a 2015 baseline, by the end of 2020.

Going forward, our energy reduction projects and activities implemented during 2019 and 2020 are forecast to reduce annual energy consumption by over 4,033 Mwh and reduce our total group scope 1 and 2 emissions by 30,922 metric tonnes CO2 equivalent. As a result, we have far exceeded our original target of 2%, instead achieving a 56% reduction based on 2015 baseline. reduction in scope 1 and 2 emissions, instead achieving a 56% reduction based on 2015 baseline.

Projects for 2020 included:

  • The optimization of the wastewater bio plant heating system at our site in Castiglione, Italy which will provide a saving of 500,000 kWh in gas usage per year. The site also replaced a rotary engine and increased vacuum efficiency on their Ecodrier plant which in addition to improved overall plant productivity also reduces energy consumption by 350,000 kWh per year.
  • Improvements made to the air compressor efficiency at our manufacturing facility in St Mihiel, France will reduce electricity demand by 85,000 kWh a year. They also completed upgrades to storage tank insulation systems which will save 140,160kWh of gas per year.
  • At our site in Ellesmere Port, UK work continued in 2020 on the rationalization and replacement of the site’s ageing electrical infrastructure with the upgrade of three further substations, saving 272,000 kWh of electricity each year. The site also made improvements to the compressed air system, reducing electricity consumption by 181,300 kWh per year. The replacement and upgrade of the lagging system on the sites stream heated storage tanks will provide an additional saving of 35,000 kWh in gas each year. The Ellesmere Port site also switched their fleet of diesel vans to electric vans powered by 100% renewable electricity.

In addition to the pipeline of energy reduction capital investment projects, the ERG also encourages and supports local initiatives. The ERG coordinates the sharing of information and learning from across the sites through regular communications and best practice meetings.
