Add the Sierra Club to another ranking organization to offer praise for UNH. This one is pretty cool: the grassroots environmental group has named the university No. 2 out of 269 on its 2018 Cool Schools list. That’s a jump of 19 spots from 2017. The ranking recognizes UNH’s national leadership in sustainability and commitment to protecting the environment, addressing climate issues and encouraging environmental responsibility through such actions as using 100-percent renewable energy to power our main campus, composting 25,000 pounds of dining hall food waste each month and being the largest provider of public transit in the state.
