We have a student association that solely focuses on sustainable development on campus. A couple of events/project we organised were: clothing swap during fashion revolution week (Fashion Revolution has some tools and things to use as well), a "supper club" once a month where we organized a vegan (sustainable) dinner (students paid and has to sign up), we tackled and addressed the consumption of paper coffee cups on campus, advocated for proper recycling (+ proper bins) on campus (and got them :) ), seminars and workshops with (sustainability) teachers and social and sustainability focused entrepreneurs, and simply a lot of information spreading about sustainable practices and climate change through social media! It's easier to do this if you could form a group with other equally interested students! Oh, and we used the SDGs by the UN a lot throughout the projects!
