Our carbon footprint
Carillion’s carbon footprint represents the total annual emissions of carbon resulting from our operations and activities.
We calculate and publish details of our carbon footprint annually. It covers direct (scope 1) and indirect (scopes 2 and 3) emissions for activities undertaken within the Carillion Group, across all geographical regions in which we operate.
Bureau Veritas has verified that the methodology applied to our carbon footprinting processes is considered to be robust.
Carbon data measurement
Collating accurate carbon data metrics is a complex challenge for a diverse global business like Carillion. We have installed smart meters across our UK businesses to provide instant, accurate readings from the electricity, gas, and oil used to power our offices, site accommodation and construction contracts.
Fuel consumption is calculated on a vehicle-by-vehicle basis, and has improved since the introduction of telematics and fuelsaver technologies across our UK and Canada commercial fleet in 2012. See Meeting our carbon targets
We submit our data to CDP – an international not-for-profit organisation providing the only global environmental disclosure system. These insights enable investors, companies and governments to mitigate risks from the use of energy and natural resources and identify opportunities from taking a responsible approach to the environment.
Our 2012 footprint
In 2012 we reduced our absolute carbon footprint by 53,948 tonnes, or 20% against a 2011 baseline. This reflects efforts across the business to reduce energy consumption and emissions arising from the operation of our facilities and vehicle fleet, as well as from employee business travel and from our clients and supply chain. See Meeting our carbon targets.
For our UK Carbon Reduction Commitment (CRC) reporting, in the 2011–2012 compliance year, we saw emissions drop from 41,393 tonnes of CO2 to 24,678 tonnes of CO2. While this significant reduction (41%) has made a positive contribution to our footprint target, it is largely as a result of structural and CRC reporting changes in the UK over this period.
We report on scope 1–3 emissions from the following sources:
- Gas – emissions calculated using kWh data from suppliers
- Commercial vehicles, company cars, plant fuel and business mileage – emissions calculated from fuel card returns
- Electricity from our offices and sites – emissions using kWh data from suppliers
- Rail travel – emissions calculated using data showing total distance travelled
- Air travel – emissions calculated using data for three categories (domestic, short haul, and long haul)
- Hotel stays – emissions calculated based upon a standard hotel stay of 48kg CO2e per person per night
- Paper – emissions calculated from total kg paper purchased and multiplied by CO2e factors provided by our paper suppliers
- Water – emissions calculated based on data showing total volume of water used (including some effluent data in MENA)
In 2012, we improved our Group-wide data collection by moving to Capture, a more accurate web-based system. This was part of a move towards gathering emissions data in-house, as we believe that this will give us a greater visibility of, and impetus to address, our performance, as we widen our scope 3 reporting.
The process continues to be verified by Bureau Veritas (see Assurance) and audited by Deloitte, who validates the data that we submit as part of the UK Government Carbon Reduction Commitment reporting scheme.
Green energy procurement
In the UK, we procure Climate Change Levy-exempt energy across our businesses where possible. Where it is not, we buy energy from Combined Heat and Power (CHP) plants. We have a supplier partnership with Scottish and Southern Energy (SSE), the UK’s largest generator of renewable energy. We now purchase all energy for our UK buildings through this route.
Within our Middle East business, renewable energy is a relatively new sector for the region, given the historic reliance on oil. However, the tide is turning and we are now installing solar photovoltaic panels at our head office in Dubai, showcasing our commitment to renewable energy and promoting our own energy services. For examples of our renewable energy services, see Sustainable solutions for our customers.
reduction in our carbon emissions
Carillion UK is accredited to the Certified Emissions Measurement and Reduction Scheme (CEMARS) for measured, managed, and verified carbon emissions.
We report emissions to the CDP
