Bart Ashton has been the Domestic Bursar at Lady Margaret Hall since 2003. Realising that he was responsible for or could influence significant elements of LMH’s direct footprint (e.g. energy, buildings, refurbishments, procurement, water, travel, commuting, food, staffing, grounds management) he founded the Oxford Colleges Sustainability Guild to help both himself and others work out what a more sustainable Oxford could look like and how we could get there.
