In the end, and disappointingly, I couldn't get to the NUS celebration of its Green Impact programme at the Commons late last month. It was an enthusiastic, sell-out crowd. NUS has helpfully written up the event (and the background to Green Impact), and you can read it here.
This is how the account begins:
"Green Impact is NUS' sustainability accreditation scheme – which now operates in students' unions, universities, colleges, hospitals, fire stations and other institutions, not only in the UK, but abroad too! The reception at the Houses of Parliament gathered an array of over 200 of Green Impact's stakeholders and supporters – from students' union staff advocates, to NUS officers past and present, to sponsors and university staff. Guests included environmentalists Jonathon Porritt and Tim Smit, James Bridge from UNESCO UK, Judy Ling Wong from the Black Environment Network, Tim Balcon from the Institute of Environmental Management and Assessment, prominent student activist Esha Marwaha, Samiah Anderson from Rethinking Economics, and Lili Sarkadi from the NUS/Friends of the Earth My World My Home project – among many others. ..."
Do read it as it's a really positive story.
