Protecting the planet is no longer a choice, but an obligation

In an increasingly environmentally conscious world, building owners and occupiers are under pressure to realise ambitious eco-friendly commitments – without breaking the bank. It’s a challenge that will endure for generations to come.

In the ever-evolving landscapes of regulation and technology, understanding the wider impact of our work is paramount. Working with a partner that understands these touchpoints releases the pressure valve, providing the confidence required to meet green commitments to our planet and communities.

Our people are industry leaders in delivering unbeatable environmentally sustainable and socially responsible spaces, and helping clients monitor and dramatically improve their performance and impact.

Whether bringing a sustainable future to a tired office block, building a zero-carbon school or even delivering a hyperscale datacentre in half the usual time, we operate at every stage of the lifecycle.

From Europe’s first WELL Platinum office in London to our wide-range of zero carbon distribution centres and ‘BREEAM outstanding’ certified spaces, we consistently help clients achieve exceptional results – ensuring everything we do leaves a lasting legacy. 

Time for revolutionary change: Aiming for net gain

We drive revolutionary change in our industry, promoting the sustainability agenda through our own business operations, and supporting our clients to achieve their sustainable business goals. We want to create a place for people to thrive in our business, deliver performance we can be proud of, support communities who are better for knowing us, and ensure environments are both protected and enhanced. 

"The aim shouldn't be to minimise damage to the environment, but to ensure that every action we take leaves a net gain society."  Debbie Hobbs, Group Director: Sustainable Business

With the steps we are taking as a business to commit to a sustainable future, we are dedicated to ensuring that we accelerate this change as soon as we can, by taking our employees, suppliers and contractors on the journey with us. With this ambition and our stakeholder activities, we are focused on four core areas:

  • Environmental management policy: this continues our best practice in managing environmental issues, but also ensures we develop a 'net gain' in biodiversity on larger projects and starts targeting water reductions at our sites
  • Climate change and carbon policy: we are committed to achieving Net Zero Carbon by 2030 and introduces an internal carbon tax by 2024, that can be used to fund sustainable innovation projects across our business
  • Circular economy policy: this aims to stretch the business, to ensure we develop our own ISG Materials Passport linked to our BIM models, for all larger projects and commits us to reusing the materials we strip out, as much as possible
  • Social value policy: we want to go further than just achieving client KPIs. We are committed to achieving a minimum of 25% social value, on every project, compared to the contract value, as costed by the Social Value Portal

    Climate change is the greatest challenge facing our planet and the built environment has a critical role to play. With a quarter of all CO2 emissions coming from buildings, the global community needs to reduce building energy consumption by over 80% if we are to reach zero-carbon targets.

    If we are to chart a sustainable future, first we need to understand where we are now.

    research and insight report launching next month, provides data on the regional emissions produced by the operation of commercial buildings.
