A thriving business for a sustainable future


We are committed to creating a place for people to thrive in our business, delivering performance we can be proud of, supporting communities who are better for knowing us, and ensuring environments are both protected and enhanced.

“In an industry where often speed and profitability reign, we emphasise care of our people, our customers, our communities and our world. We achieve this goal by living our values to the fullest: dream smart, speak frankly, always care and never stop learning.”

Paul Cossell, Chief Executive Officer, ISG

2021 Sustainable Business Strategy

In 2017, we reviewed our 2020 Sustainability Vision in line with ISG’s new vision, values and corporate goals. As our corporate strategy extends to 2021, we have re-aligned our sustainability strategy with this end date. Accordingly, our 2020 Sustainability Vision is now our 2021 Sustainable Business Strategy.

Our areas of focus around People, Performance, Communities and Environments remain the same, and in fact, strongly mirror our corporate goals around customer satisfaction, employment experience, operational efficiency and driving revolutionary change in the industry.

We have introduced new key performance indicators (KPIs) to better capture and report our performance across the business, which are also aligned with the UN Sustainable Development Goals (SDGs). We have set ourselves challenging targets for 2018, 2019 and 2020, which reflect our business ambitions.

Our areas of focus


Happiness, pride and engagement: All are measures of employees desire to turn up to work every day and make a difference. We recognise that a sustainable business is powered by its best people – their contributions, values and ideas – and so we won’t settle for anything less than a top position among the best companies to work for.

Sustainable growth of our business relies not only on our bottom line, but also on fulfilling our promise to our people, customers and communities. To this end we establish short- and long-term performance goals that define the means as much as the ends. We focus on factors like customer satisfaction, repeat business, and strategic supply chain investment.

At the same time, we work to give back o those communities where possible, sharing our skills, knowledge and time to improve the world around us.

We are all responsible for protecting and preserving our natural environments; as a construction services company responsible for shaping the places of tomorrow, we take that responsibility particularly seriously. Not only do we challenge our construction teams to resource efficiently, but we strive to be leaders for our customers in achieving or surpassing their environmental goals.

Towards 2021

Since launching our first sustainability strategy in 2013, we have made steady progress in our focus areas of People, Performance, Communities and Environments. Our reporting has dramatically improved during this period, and our efforts have shifted from data gathering to analysis and implementing change. We now have stretching targets in all areas for every year up to 2021. Download our sustainable business targets for more details.
