Sustainability in Milk Selection
You manage a café that prides itself on sustainability. Currently, you offer dairy milk from a local farm that uses conventional practices, and you also offer oat milk and almond milk. The café uses about 100 liters of dairy milk per week and 20 liters of oat milk and 10 liters of almond milk. The local dairy farm is 50 km away, and the milk is delivered twice a week in reusable containers. The oat milk is produced by a company that sources oats from 500 km away and packages in Tetra Pak cartons, which are not widely recyclable in your area. The almond milk is imported from California, where almond farming uses significant water. Your customers are increasingly asking about the environmental impact of their choices. You want to reduce the café's carbon footprint and water usage while maintaining quality and customer satisfaction. You have a limited budget for marketing and staff training.
1. Compare the environmental impact of the three milk options (dairy, oat, almond) considering the information given. Which option appears most sustainable and why?
Read the worked answer
Dairy: local (50 km) reduces transport emissions, reusable containers reduce packaging waste, but conventional dairy has high methane emissions and water use. Oat: plant-based, lower water and land use than dairy, but long transport (500 km) and non-recyclable packaging increase footprint. Almond: plant-based but grown in water-scarce California, high water use; imported long distance. Overall, oat milk likely has the lowest environmental impact per liter, despite packaging and transport, because plant-based milks generally have lower GHG and water footprints than dairy. However, the local dairy has advantages in packaging and transport. A life-cycle assessment would be needed for precision. For a café, promoting oat as default and sourcing locally produced oat milk in recyclable packaging would be best.
2. What practical steps could you take to improve the sustainability of your milk offerings without compromising quality or customer experience? Consider sourcing, packaging, and menu design.

- Source oat milk from a closer producer or one that uses recyclable packaging; if not possible, advocate for better packaging. 2) Offer a discount for customers who bring their own cup, but that's for beverages. 3) Reduce dairy milk waste by tracking usage and training staff on proper steaming and storage. 4) Introduce a 'sustainable choice' default: make oat milk the standard for milk-based drinks unless customers request otherwise, which can reduce dairy use. 5) Educate customers via menu notes about the environmental impact of each option. 6) Explore local plant-based milk alternatives (e.g., hemp or soy) that might have lower transport. 7) Work with the local dairy to improve practices (e.g., regenerative agriculture) and highlight their localness. 8) Consider offering a blend of oat and dairy to reduce dairy consumption while maintaining taste.
