Solutions to transform our world
RSK is a well-established global leader in the delivery of environmental and engineering solutions. We recognise the urgent need for sustainable change and know that this will be achieved by delivering meaningful action, not just words. We are committed to supporting our clients and societies as they navigate these complex challenges, while making a positive impact.
The business was founded in 1989, originally focused on providing environmental consultancy services to global energy clients. Today, while we remain a leader in environmental consultancy, the business is significantly more diverse. RSK delivers an unrivalled breadth and depth of environmental and engineering services, either as stand-alone projects or as large and integrated multidisciplinary solutions.
The group believes this emphasis on multidisciplinary collaboration is essential for successfully addressing complex global challenges. This is why we have brought together pragmatic advice, forward-thinking engineering, cutting-edge innovation, digital solutions and best-in-class delivery services. To support this, RSK comprises more than 200 companies and employs over 17,000 people, covering an unrivalled breadth and depth of expertise.
