Since we started monitoring our energy use and emissions against our 2006 baseline year, our energy and carbon reduction has been significant. In 2018, we have delivered a range of activities and investments to further increase our energy efficiency and reduce our greenhouse gas emissions (GHG).
- 2018 Performance
In 2018, we reduced the energy intensity of production (GJ consumption per metric tonne of product) by 4% compared to 2017 and by 17% against our baseline year in 2006. This reduction in intensity is also reflected in our Scope 1 and 2 emissions per metric tonne of product that have reduced by 6% since 2017 and 30% since 2006. Alongside more efficient use of energy, we have also reduced our absolute emissions by 1% since 2017 and 22% 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.
In 2018 the fund targeted projects that could help deliver the 2017 and 2018 objective of achieving a 2% (1,104 metric tonnes) reduction in our Scope 1 and 2 emissions, based on a 2015 baseline, by 2020. This included the following projects which are forecast to reduce emissions by approximately 1,852 metric tonnes CO2 equivalent, exceeding or 2% target by 748 metric tonnes annually;
- Installation of a new combined heat and power (CHP) plant at our St Mihiel facility in France.
- Installation of a new economizer for steam boilers at our Ellesmere Port, UK site.
- Installation of a new condensate listing station at our Herne, Germany site
- An upgrade to LED lighting at our Pleasanton, TX, US facility
- Efficiency improvements to the water heating system at our Herne, Germany Site.
In addition to the pipeline of energy reduction capital investment projects, the ERG also encourages and supports local initiatives. The ERG co-ordinates the sharing of information and learning from across the sites though regular communications and best practice meetings.
