Catering typically accounts for 15–20% of a corporate retreat budget—and up to 30% of its food-related carbon footprint. In 2026, the focus is on sustainable menus, local seasonal products, and reducing food waste. This guide shows you how to implement responsible catering without compromising on culinary enjoyment.

The Challenges of Event Catering
A buffet for a corporate retreat of 50 people generates on average 7 to 12 kg of food waste and uses 400 pieces of disposable tableware. A meat-heavy menu for the same group equals the carbon footprint of 180 km driven per person. These figures, from ADEME (2024), highlight why event catering has become a strategic focus in large companies’ CSR policies.
Practical Zero-Waste Solutions
Three high-impact actions: (1) eliminate disposable tableware (saving 60% of solid waste), (2) partner with a caterer who collects and redistributes leftovers after the event (via Too Good To Go, Phénix, or local charities), (3) use bulk options for coffee breaks (no more single-use capsules, plastic bottles, or sugar packets). These steps reduce waste at a 50-person corporate retreat by an average of 65%.
Sustainable Gastronomy and Participant Experience
Sustainable catering does not mean sacrificing enjoyment—often, it’s the opposite. Menus built around local, seasonal produce and prepared by chefs who highlight forgotten vegetables and short supply chains are often more memorable and distinctive than standard buffets. Adding a local producer’s testimony during the meal, a garden visit, or a tasting of local natural wines turns lunch into a moment of learning and team bonding.
