15.1 Sustainability and environmental footprint
Let us begin by linking this discussion to the earlier treatment of consumer habits and food safety.
In light of the worsening climate situation and the growing environmental impact of food production, it is unavoidable that operators in the restaurant sector place greater emphasis on sustainability across all aspects of their operations.
Food waste is one of the major challenges of our time. According to Sigurðardóttir (2023), food waste accounts for approximately 17% of all food produced globally (Sigurðardóttir, 2023).
Restaurants can reduce this waste through accurate control systems that monitor ingredient use and production, while also encouraging the reuse of ingredients through portion management or innovation in recipe development (European Commission, 2022).
The carbon footprint of restaurant operations is not only shaped by the climate impact of transport and energy use, but also by packaging. Packaging solutions based on recyclability or circular economy principles can significantly reduce the carbon footprint of restaurants (European Commission, 2022).
Responsible sourcing and shorter supply chains are the next step toward sustainability, with emphasis placed on local food products and collaboration with farmers who work according to organic or ecologically responsible production methods (Sigurðardóttir, 2023).
By reducing the distance ingredients must travel, businesses gain not only fresher and more flavourful products, but also a lower carbon footprint from transportation and refrigeration (European Commission, 2022).
Energy use in restaurants calls for circular thinking in the design of both kitchen and dining areas, for example through renewable energy, heat recovery ventilation, and responsible waste handling for composting.
This approach supports a reduction in environmental impact while also strengthening the operator’s profile in the eyes of environmentally conscious consumers (World Economic Forum, 2024).
