350.org works on grassroots campaigns across the globe, leveraging people power — individuals working together in pursuit of a common goal — to dismantle the influence and infrastructure of the fossil fuel industry and to power up clean systems rooted in justice. To build a more sustainable and just future, we collaborate with communities at the frontline of the climate crisis, those who have historically contributed the least emissions but are feeling the worst effects. We campaign and organise to show the world we really want, in pursuit of energy justice and distributed renewable energy solutions that will move us away from fossil fuels, for good. Over the past 15 years, we have mobilised with people around the world to confront injustice and challenge our fossil-fuelled economic systems. Together, we have achieved extraordinary things, from getting millions of people onto the streets worldwide, to moving trillions of dollars away from the fossil fuel industry, to stopping dirty coal, oil and fossil gas plants and pipelines. We take on ambitious fights – and we often win!
