Campus Sustainability Day, Oct. 22, featured a campuswide idea exchange for reducing Cornell's carbon footprint and talks with campus leaders on strategies for achieving climate neutrality. Other activities included free samples of locally grown food, a tour of Weill Hall and a display of a 100-mpg car being developed at Cornell.
