This is the website of 350 movement that was founded in 2008 by a group of university friends in the United States along with author Bill McKibben, who wrote one of the first books on global warming for the general public, with the goal of building a global climate movement. 350 was named after 350 parts per million -- the safe concentration of carbon dioxide in the atmosphere.

The movement’s first activities were global days of action that linked activists and organizations around the world, including the International Day of Climate Action in 2009, the Global Work Party in 2010, Moving Planet in 2011. 350 is today a planet-wide collaboration of organizers, community groups and regular people fighting for divestment from fossil fuels and lowering global CO2 emissions. 350 works on grassroots campaigns across the globe: from opposing coal plants and mega-pipelines, to building renewable energy solutions and cutting financial ties of the fossil fuel industry. 350 seeks to leverage people power to dismantle the influence and infrastructure of the fossil fuel industry.

The 350 website is full of science-backed resources on the subject of climate change and the negative consequences of continued reliance on fossil fuels. Apart from the research on climate change the website also provides many resources for advocates and campaigners as well recent updates on various climate-related events and campaigns from across the world. Being one of the largest alliances of civil society and individuals on the subject of climate change the work of 350 and its partner organizations may prove to be useful allies in building alliances.

The website offers many further links to other organizations, campaigns, movements and resources that engage with the same topics. Although the movement argues for “technological” solutions to climate change (a transition to 100 % renewable sources of energy) that do not seem to be explicitly challenging extractive, exploitative, growth-based global economy, nor its underlying consumerist culture, the information and resources available on the website do offer valuable insights into climate change debates, materials that can help organize effective campaigns and could also provide a starting point for new partnerships.
