SDG 6: Clean Water and Sanitation — How Restaurants Contribute

SDG 6 focuses on ensuring availability and sustainable management of water and sanitation for all. Foodservice operations are significant water consumers, using water for food preparation, cleaning, dishwashing, and cooling. Food waste also has an embedded water footprint — every kilogram of wasted food represents the water used to grow, process, and transport that food.

The United Nations adopted the 17 Sustainable Development Goals in 2015 as a universal call to action to end poverty, protect the planet, and ensure prosperity for all by 2030. SDG 6 — Clean Water and Sanitation — is particularly relevant to the food service industry, which sits at the intersection of food production, consumption, environmental impact, and community health. Restaurants, hotels, hospitals, and institutional food service operations have both the opportunity and the responsibility to contribute meaningfully to this goal.

For food service operators, engaging with SDG 6 is not just an ethical imperative — it is increasingly a business necessity. Corporate clients, government procurement programs, and sustainability-conscious consumers are all demanding evidence of SDG alignment. Operations that can demonstrate their contribution through quantified data have a competitive advantage in an evolving marketplace.

Canada has committed to the SDG framework at the federal level, and provinces are incorporating SDG-aligned targets into their own environmental and economic policies. For food service operators, this means that SDG alignment is not a distant aspiration but a practical consideration that affects regulatory compliance, client relationships, and market positioning today.

The food service industry's contribution to SDG 6 extends across the entire value chain — from ingredient sourcing and purchasing decisions to kitchen operations, guest service, and waste management. Every operational decision has implications for this goal, whether it is choosing suppliers, designing menus, managing inventory, or handling surplus food.

Measuring your contribution to SDG 6 requires structured data collection and impact assessment, in terms that stakeholders — from corporate ESG teams to government agencies to your own guests — can understand and verify. BonAppify's reports include an SDG 6 section when your audit and monthly data support it, with the figure behind it, and the app's SDG view lights SDG 6 only then.

Food service accounts for around 28% of the food wasted worldwide at retail, food service and household level (UNEP Food Waste Index Report 2024). By addressing this waste through systematic auditing and targeted reduction strategies, food service operators can make a meaningful contribution to SDG 6, and even modest reductions add up when multiplied across thousands of operations.

Contributing to SDG 6: Clean Water and Sanitation as a food service operator begins with understanding that meaningful impact does not require dramatic operational upheaval. The most effective approach is incremental — start with measurement, identify high-impact opportunities, implement targeted changes, and track results over time. Your first sustainability audit provides the baseline data that transforms abstract SDG targets into concrete operational priorities specific to your kitchen, your menu, and your team. Many operators discover that their largest sustainability opportunities align perfectly with their biggest cost-saving opportunities, making SDG contribution a financially rewarding endeavor rather than a purely altruistic one.

Begin by engaging your entire team in the conversation about SDG 6. Kitchen staff, servers, and management all play roles in your operation's sustainability footprint, and each brings unique insights about where improvements are possible. Share the UN's description of Clean Water and Sanitation in terms your team can relate to — connect global targets to daily kitchen decisions like portion sizing, ingredient storage, production planning, and surplus management. When team members understand that their daily work contributes to a global goal, it creates a sense of purpose that improves both engagement and retention. Formalize this engagement by designating sustainability champions on each shift who take ownership of data collection and serve as peer mentors for sustainable practices.

Operational changes that contribute to SDG 6 span the entire food service value chain. On the procurement side, consider supplier selection criteria that reward sustainable practices, seasonal menu planning that reduces transportation emissions, and inventory management systems that minimize spoilage. In production, focus on accurate demand forecasting, cross-utilization of ingredients to reduce trim waste, and standardized recipes that optimize portion sizes. For surplus management, establish partnerships with food recovery organizations, implement staff meal programs that repurpose usable surplus, and ensure proper waste separation for composting. Each of these practices contributes to SDG 6 while simultaneously improving your operation's financial performance and operational efficiency.

Technology makes measurement easier to sustain. BonAppify's platform is designed to lower the barrier to entry for food service operators of any size — from independent restaurants to multi-location hotel chains: no hardware, a phone, tablet or computer is enough. The team records the waste by shift and by category during an audit, and the platform does the totals, the money value, the footprint and the SDG view, so your team can focus on the operational changes that drive impact rather than on compiling data by hand.

Tracking your contribution to SDG 6: Clean Water and Sanitation requires a structured approach to data collection that captures the metrics stakeholders care about. For food service operations, the most relevant metrics include waste volumes by category, financial cost of waste, environmental impact in CO2 equivalent, water footprint, and land use — which BonAppify calculates from your audit and monthly data, with the method published. Quantified metrics turn an SDG contribution from a vague aspiration into figures you can show corporate ESG teams, buyers and environmentally conscious consumers, with the method behind them. Consistent measurement over multiple audit cycles also reveals trends that demonstrate continuous improvement, which is ultimately more compelling to stakeholders than any single data point.

Communicating your SDG 6 impact effectively requires tailoring the message to each audience. For corporate clients and institutional buyers, emphasize quantified environmental metrics, alignment with specific SDG targets, and year-over-year improvement trends — these audiences are sophisticated and expect data-backed claims. For guests and consumers, translate the numbers into relatable terms: kilograms of CO2 prevented (equivalent to driving distances or trees planted), liters of water saved, or meals donated through food recovery partnerships. For your own team, focus on the connection between their daily actions and the measurable impact — when a line cook sees that the prep station's waste reduction last month prevented 200 kg of CO2 emissions, it reinforces the value of their effort in tangible terms.
