Meaningful work continues

All of ISS UK’s social value initiatives are rooted in its UK & Ireland’s Sustainability Framework, which delivers social and environmentally sustainable workplaces through:

• Enterprise Sustainability: operating responsibly and transparently, guided by strong values and clear commitments

• Sustainable Workplaces: embedding sustainability into everyday service delivery, through our people on site

• ISS Sustainability Services: helping customers go further through structured, outcome-focused programmes through Low Carbon Workplaces, Zero Waste Workplaces and Socially Responsible Workplaces.

ISS is working with its customers to drive meaningful and measurable sustainable change across their workplaces. By embedding socially and environmentally responsible practices, ISS is supporting customers to reduce emissions, minimise waste, strengthen social impact and create more inclusive and healthy workplace environments.

Richard Crawshaw, Sustainability Director, ISS UK & Ireland, commented: “In recent years we have redoubled our focus on operating in the most environmentally and socially responsible ways. As we continue to refine our strategy, we remain firmly committed to driving meaningful social and environmental impact.  

“This report focuses on what Sustainability means in practice for our customers across our sustainability framework: Enterprise Sustainability, Sustainable Workplaces and ISS Sustainability Services. Together, these show how our Sustainability Framework moves from ambition to action, creating measurable outcomes in real workplaces and supporting our customers wherever they are on their journey.”
