In tandem with the International Day of Awareness of Food Loss and Waste, ISS has proudly announced a significant 30% reduction in food waste from their 2019 baseline. As a leading workplace experience and facility management company, ISS plays a crucial role in providing services at offices, factories, airports, hospitals, and other locations worldwide. Given its broad global footprint and engagement with diverse communities, this significant reduction in food waste not only demonstrates ISS's commitment to sustainability but also has a substantial, positive impact on the environment and communities they serve. This achievement aligns ISS steadfastly on the path to realising its ambitious target of a 50% reduction in food waste by 2027.

ISS’s triumph in sustainability is deeply intertwined with its strategic partnership with Winnow. Our advanced AI solutions have been integral in this venture, providing invaluable insights into plate waste and consumer behaviour. Integrated into ISS kitchens worldwide, Winnow’s technology empowers chefs to meticulously optimise food production and portion sizes, effectively minimising food waste.

With Winnow’s technology integrated into their operations, ISS has achieved incredible results. Their kitchens around the globe have prevented 985,000 tonnes of food from being wasted - equivalent to 2,463,000 meals each year. As food waste is a major contributor to global greenhouse gas emissions, these savings have reduced the carbon footprint of ISS by 4,200 tonnes per year. 

ISS is deeply committed to fostering sustainable and healthy food options. Last year, they pledged to the World Resource Institute’s Cool Food Pledge, aiming to cut greenhouse gas emissions by 25% by 2030. As part of their comprehensive approach, ISS collaborates with Unilever and the WWF, incorporating the ‘Future 50 Foods’ into their global recipes. These initiatives, alongside their global awareness campaigns, underscore ISS's commitment to driving the climate agenda collaboratively and conscientiously.

“In the end, driving the climate agenda is a collective responsibility, demanding consistent awareness and commitment,” says Hamish Cook, Head of Group Food Services at ISS. The company not only supports global sustainability initiatives but also actively engages in awareness campaigns, such as the International Day of Awareness of Food Loss and Waste.

Beyond the immediate concern of food waste, ISS envisages a future of net-zero greenhouse gas emissions. With a clear roadmap to achieve net-zero emissions within its operations by 2030 and across its supply chain by 2040, ISS is steadfastly committed to the wellbeing of the planet, its people, and the communities it serves.
