Students in Imperial's RSM cafeGreening Imperial is a cross-campus and community initiative that aims to make Imperial a pioneer and exemplar in sustainability. Greening Imperial’s achievements include working with the Campus Services team to help bring about a 20% reduction in meat consumption in catering outlets from 2017–18 to 2018–19 thanks to changes in customer choice, tweaks in menu options and an increase in vegetarian and vegan options.

The initiative has also hosted the Greening Imperial Week, an Imperial College Union-led showcase of events and activities around campus focused on sustainability and the environment. Each day of the week highlighted a different theme, from food, travel and waste, to energy and lifestyle, offering students and staff the opportunity to learn about the small adjustments they can make to their daily routines to help the environment.
