Latest ENR rankings reveal WSP as one of the world’s largest environmental consultancies

WSP now has sixth largest environmental consulting business in the world which reflects progress towards its ambition to be the premier global environmental consultancy

WSP, the engineering professional services consultancy, now has the sixth largest environmental consulting business in the world, as published in Engineering News-Record’s 2020 Top 200 Environmental Firms ranking.

Revealed as one of the world’s largest and fastest growing consultancies, WSP has moved up from 16th place in 2019 and 38th in 2018 to sixth in 2020, building on ten years of consistent growth.

ENR’s annual table is one of the most important benchmarks for the consultancy sector, based on global revenue during the previous calendar year. WSP’s strong performance reflects progress towards its ambition to be the premier global environmental consultancy, outlined in the firm’s 2019-2021 global strategic plan.

WSP now employs 7,000 environmental consultants worldwide, within the global total of 50,000. In 2019, its revenues from environmental services were US$1.34bn (C$1.72bn), an increase of 14% on 2018.

WSP’s improved 2020 ranking is based mainly on strong 2019 organic growth (eight per cent), with the full benefits of key acquisitions still to be felt.

Barry Cowell, UK Head of Environment at WSP, said: “It’s fantastic to be recognised by ENR as one of the largest and fastest growing environmental consultancies in the world, as this aligns with WSP’s global strategic plan.

“In the UK, heightened acknowledgement of the risks posed by climate change and the impact this will have on both the natural and built environment has allowed us to work closely with both public and private sector clients, developing resilience strategies and future ready plans to protect and enhance biodiversity, communities and infrastructure.

“Looking forward, the UK’s transition to net zero by 2050 is front of mind for many of our clients and this will mean the decarbonisation of many elements of our society, including heat, transport and energy. The development of clean energy sources through hydrogen will play a key role in our ability to meet the 2050 target and we will look to support our clients with opportunities in this sector.”

WSP’s achievement is partly down to the strategic expansion of its high-quality advisory services, supporting clients with challenges such as climate change, resiliency and pollution.

WSP entered ENR’s top ten for Consulting / Studies in fourth place, off the back of high-profile projects including HS2 in the UK, the Trans Mountain Pipeline in Canada and Hudson River remediation in the USA. Its focus on growing both global footprint and service coverage is also reflected in other new rankings, including fourth for Air Quality / Clean Energy, 13th for Hazardous Waste and 18th for Wastewater.
