The 350 in the name stands for 350 parts per million (ppm) of carbon dioxide (CO2), which has been identified as a safe upper limit to avoid a climate tipping point. By the end of 2007, the year 350.org was founded, atmospheric CO2 had already exceeded this threshold, reaching 383 ppm CO2; as of July 2022, the concentration had reached 421 ppm CO2, a level 50% higher than pre-industrial levels.
Through online campaigns, grassroots organizing, mass public actions, and collaboration with an extensive network of partner groups and organizations, 350.org mobilized thousands of volunteer organizers in over 188 countries. It was one of the many organizers of the September 2019 Global Climate Strike, which evolved from the Fridays for Future movement.
