Protecting the Environment

What protecting the environment means to us

We are committed to limiting the impact our operations have on the environment through more sustainable business practice.





Our policy and commitment

Our commitment is defined within our Health, Safety and Environment (HSE) Policy Statement, supporting standards and related operating procedures, aligned to the ISO14001:2015 standard on Environmental Management.

In summary, we strive to:

  • promote a commitment to the environment based on active and caring leadership and mutual trust, innovation and pride;

  • minimise adverse environmental impact through the implementation of environmental management systems that are proportional to each contract, aligned to customer specification and contractual requirements, and underpinned by our Group Standard Operating Procedure for Health, Safety and the Environment;

  • actively encourage input from employees and others to build sustainable solutions, helping us make decisions based on a deep understanding of work conditions and constraints;

  • identify and assess the environmental hazards, impacts and risks that arise from our activities and services, investigating incidents and monitoring performance and systems; and

  • regularly review, learn and identify opportunities for continual improvement.

Key components in our governance

  • Our Corporate Responsibility Committee (CRC) provides formal review and oversight of environmental strategy and performance against agreed objectives and targets. The CRC, Executive Committee and Divisional Executive Management Teams (EMTs) review operational and strategic HSE performance reports.

  • Our Group Business Compliance and Ethics Lead is responsible for developing and maintaining associated policy and governance, and chairs the HSE Oversight Group (including Divisional HSE Leads), which meets regularly to discuss strategic and operational HSE performance and share best practice.

  • Divisional EMTs are responsible for appropriate Divisional adherence to policy and standards and managing associated risks, while Divisional HSE Leads are responsible for implementing policy and governance across the Division. In addition, we have c.150 operational HSE leads, supported by a small team of Environment, Energy and Sustainability experts, advising on HSE issues whilst ensuring company policy and management systems are properly applied and aligned to business requirements.

  • Where we have direct control of environmental impacts, activities are managed locally, covering a wide range of initiatives focused on energy and fuel efficiency; greenhouse gas emissions; resource efficiency; waste hierarchy improvements; pollution prevention; supply chain; biodiversity and climate resilience.

  • Across more than two thirds of our business we work on our customers’ premises and are not in direct control of environmental impacts. In such cases we work collaboratively with our customers, supporting them in applying their own environmental management systems and objectives.

  • Our contract-level Planned General Inspections plus independent compliance assurance reviews and internal audit programmes provide comprehensive coverage of environmental issues.

  • We gain external independent review of performance via certification to the ISO14001:2015 standard on Environmental Management in pertinent areas of our operations. We are also audited globally to the ISO14064-3:2006 standard on validation and verification of Greenhouse Gas assertions, providing assurance on our annual carbon reporting.

Our progress and performance in 2017

 We have:

  • benchmarked our approach to climate change via the globally-recognised annual Carbon Disclosure Project (CDP) climate change questionnaire, achieving a score of B (of all participating companies 23.3% scored A, 24.4% scored B and 52.3% scored C or D, while within our sector 22% scored A, 21.6% scored B and 56.4% scored C or D) – further information can be found on the CDP website, www.cdp.net/en;

  • undertaken an initial Scope 3 carbon emissions assessment to identify priority areas in our indirect carbon emissions; and

  • investigated the Science Based Target methodology to inform our future carbon target setting.

Key performance indicators

For additional data and performance commentary, see all our corporate responsibility key performance indicators.

  Key performance indicators:




Carbon dioxide equivalent (tonnes CO2e) Scope 1:
Combustion of fuels and operation of facilities




tCO2e Scope 2: Grid electricity purchased for own use

(Total Group tCO2e/FTE)





Our next steps

We will finalise development of a new environmental strategy to consolidate performance to date and refocus our activities to address priority environmental issues by taking a broader lifecycle approach to our environmental impacts.
