UK & Ireland energy management

Our approach to energy management

Energy consumption is our second largest source of greenhouse gas emissions (17%). We’re continually striving to improve energy efficiency, limit consumption and reduce our related GHG emissions by investing in new technologies, process improvements and a renewable energy procurement strategy.

Since October 2007, for offices where we can control the energy supply, and appropriate renewable energy tariffs are available, we have purchased electricity from renewable sources (see Green tariffs and Market–based scope 2 emissions reporting).

And in January 2018, we switched from fossil fuel-based natural gas to biogas.  So now 100% of the energy we procure in the UK is from renewable sources.

Measures we use to minimise our energy consumption include:

  • Destination lift control software, maximising operating efficiency and reduces energy demand
  • Energy efficient IT monitors that switch to standby after a short period of non-use
  • LED lighting installations and zonal PIR / movement activated lighting controls
  • Thermostatic office temperature control and upgrades to building cooling systems
  • Multi-functional print and copy devices that switch to standby when not in use
  • Vending machines which go into sleep mode in periods of low demand
  • Energy audits to identify performance improvement areas
  • Online energy data collation, monitoring and analysis
  • Building Management Systems to monitor and regulate energy use
  • Participation in climate-change related events (e.g. WWF’s Earth Hour campaign)
  • A robust environmental communications programme to increase staff awareness of energy consumption and related impacts, encouraging behavioural change at work and at home

Our UK operations have been certified to the Carbon Trust Standard for Carbon since 2010. This internationally recognised framework certifies that we have measured, managed and reduced our Carbon emissions across our operations, and are committed to reducing them year on year.

We are also a full participant in the UK Government's Carbon Reduction Commitment Energy Efficiency Scheme (CRC).

Performance against our FY2018 targets

Reduce total energy (kWh) consumed by 5% per m2 (base year FY2017): In FY2018 total electricity and gas (kWh) consumption per m2 rose 14% compared to the base year (FY2017). However, absolute energy consumption saw a small decreased overall. We believe the increase was mainly due to a prolonged period of extremely cold weather during Q1 2018 which increased heating demands in our buildings considerably, as well as an exceptionally warm, prolonged summer, which increased cooling demands. We are confident that our programme of energy efficiency projects will deliver a more energy efficient estate overall under normal operating conditions.

Procure at least 95% of electricity from renewable sources (where consumed in EY controlled buildings and appropriate ‘green’ tariffs are available to purchase from energy suppliers): In FY2018 100% of this electricity was purchased via an appropriate renewable energy tariff (where green tariffs were available in the local energy market), and this will continue for the foreseeable future as part of our overall energy procurement strategy. In January 2018, we switched from fossil fuel-based natural gas to biogas, so now all energy procured in the UK is from renewable sources.
