350.org is an international environmental organization addressing the climate crisis. Its stated goal is to end the use of fossil fuels and transition to renewable energy by building a global, grassroots movement.[2]

The 350 in the name stands for 350 parts per million (ppm) of carbon dioxide (CO2),[3] which has been identified as a safe upper limit to avoid a climate tipping point.[4][failed verification][5] By the end of 2007, the year 350.org was founded, atmospheric CO2 had already exceeded this threshold, reaching 383 ppm CO2;[5] as of July 2022, the concentration had reached 421 ppm CO2, a level 50% higher than pre-industrial levels.[6]

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.[7] It was one of the many organizers of the September 2019 Global Climate Strike, which evolved from the Fridays for Future movement.
