Given the planet’s growing demand for finite fossil fuels and the need to abate greenhouse gas emissions, reducing energy demand and consumption across our offices remains a key priority for Capgemini. We are also taking action to ensure more of our office energy is purchased from a renewable or self-generated source.

Our 2017 target

To reduce office energy consumption by 20% by 2020 & 40% by 2030 (compared to a 2014 baseline year)


Since 2014 we’ve reduced our office energy consumption by a further 11%, building on the 40% reduction achieved between 2008 and 2014

Currently office energy consumption accounts for 15% of our total carbon emissions. Our energy management approach (which was ISO50001 certified in 2014) has enabled us to achieve a significant improvement in the energy efficiency of our offices.

How we’ve achieved this reduction:

Since the inception of our environmental sustainability programme in 2008, we’ve invested in upgrading the infrastructure of our buildings in order to improve their energy efficiency. We’ve also automated lighting, cooling and heating systems using smart building technology to further increase efficiency. Other initiatives include:

We are also taking action to ensure more of our office energy is purchased from a renewable or self-generated source. Where we have operational control over the building, we purchase energy from a renewable source:

In 2016, 77% of our total office energy originated from a renewable energy source.

Case studies:


Our Aston office has become a flagship for new sustainable building technologies. In February 2015, we installed rainwater harvesting equipment at this site, enabling us to use rainwater for flushing toilets and reducing mains water costs. In June 2015, we completed the installation of solar photovoltaic panels on the roof, which complement the small solar thermal system already in place at this site. The panels have already generated over 58,000 kWh electricity enough to power 15 homes in the UK for one year (based on average annual domestic energy consumption).


Our newly refurbished London Holborn office embraces modern, collaborative, activity-based working to the full. It also demonstrates excellence in sustainable and eco-friendly design with these factors being considered from the inception to the completion of the refurbishment.

Advances in video conferencing technology have radically changed the way businesses operate, reducing the need for time consuming and carbon intensive business travel. As part of the Holborn refurbishment, all of our meeting rooms were fitted with the technology needed to host a video conference through Skype for business.

As well as improving the technological capabilities of the Holborn office, we also updated the décor and furnishings, to deliver a more modern and contemporary office environment. When purchasing new office furniture, environmental credentials were considered alongside cost and durability to ensure the items were in-keeping with our commitment to sustainability. Furthermore, we took measures to divert any waste generated away from landfill by either, re-using in other offices, breaking down for recycling, or where possible donating to other organisation to extend the items lifecycle. For example, we partnered with Birmingham City University, donating old office furniture and IT equipment for one of their new facilities.
