Sustainable food in action at the University of Cambridge!

The University Catering Service (UCS) have taken a lead on sustainable food issues at the University through a Sustainable Food Policy. However there are many other catering outlets at the University of Cambridge which don't fall under the control of the UCS, as well as the 31 Colleges at Cambridge which operate separately from the University. Many of them are taking significant and tangible action on sustainable food issues. On this page we've gathered some examples and case studies all about how sustainable food issues are being tackled around the University!

Update: Single-use plastics

The battle to reduce the use of single-use plastics has captured the nation's imagination and the University of Cambridge is doing its bit. Actions to reduce plastic are now also highlighted under the headings below!

Have a story to share with us?

Cambridge Institute for Sustainability Leadership (CISL)

At CISL, the Green Impact team has done much work to gain a 'Gold' Green Impact award improving their environmental performance in the workplace significantly. They then determined that one of the big environmental impacts that the department had was its use purchase of food, particularly for events. The institute therefore initiated a ‘Sustainable Food At Work’ project which aimed to use food, and the interaction with food topics within the department, as a means of promoting sustainability. Work within this project included reinvigorating the departmental vegetable patch by surveying staff and recruiting 21 staff volunteers to work on the garden, reviewing internal food and beverage purchasing to ensure the use of 100% Fairtrade and organic products, drafting new sustainability guidance for staff booking catering at external events, and drafting guidance for external suppliers. You can download copies of their guidance here.

Cambridge Trust

The Cambridge Commonwealth European & International Trust are a Silver 'Green Impact' award winning team who work hard to address their environmental impact. During 'Spotlight on Food Month' the team hosted a visit by a member of Cambridge Sustainable Food to enlighten staff on a range of sustainable food issues. The team have also looked at utilising the small roof garden on their office. As well as a growbag for tomatoes and strawberries, there are now pots of salad leaves and broad beans, ready for staff to eat when the vegetables can be harvested. There is no direct water supply to the roof garden, but a collection of unwanted wastepaper bins have been roped in as water collectors! It is also paying off in terms of supporting wildlife - decorative plants such lavender and geraniums have been visited by bees (and even the odd slug or two has made an appearance - not such welcome visitors!). You can read more about this story on their website.
