300.org urges return of atmospheric CO2 to 300 ppm from the current unsafe 387 ppm.

300.org exists to inform people about the Climate Emergency and the need to reduce atmospheric carbon dioxide (CO2 ) concentration to a safe and sustainable level of about 300 ppm.

The fundamental position of 300.org is that “There must be a safe and sustainable existence for all peoples and all species on our warming-threatened Planet and this requires a rapid reduction of atmospheric carbon dioxide concentration to about 300 parts per million”.
