People's Petition to Cap Carbon Dioxide Pollution at 350 Parts Per Million
Prominent climate researchers have warned that we must reduce the level of atmospheric carbon dioxide to 350 parts per million (ppm) or below in order to stabilize climate change and avoid global catastrophe. The Center for Biological Diversity, along with Bill McKibben's group 350.org, is advocating strongly for this necessary standard.
While carbon dioxide isn’t the only global warming pollutant we need to control, it’s the number-one contributor to climate change.
Please take one minute to join us in moving toward a real solution to the climate crisis by calling on the U.S. Environmental Protection Agency to do its job as science, the law and common sense require. Sign the People's Petition to Cap Carbon at 350 Parts Per Million today.
I support the legal petition filed by the Center for Biological Diversity and 350.org to the EPA to cap atmospheric carbon dioxide levels at 350 parts per million -- the level science says is necessary to avoid the worst impacts of global warming -- under the Clean Air Act.
For four decades, the Clean Air Act has protected the air we breathe through a proven, successful system of pollution control that saves lives and creates economic benefits exceeding its costs by many times. It's time to fully use one of our strongest existing tools for reducing greenhouse gas pollution: the Clean Air Act.
Now is the time to enforce the Act, not gut it. I urge you to move swiftly to grant the petition and enforce the Clean Air Act.

Several lines of evidence show that allowing atmospheric carbon dioxide levels to remain above 350 ppm for a sustained period of time will lead to dangerously acidic oceans, runaway global warming, and melting of the polar ice caps. Such a climate would be well outside anything experienced in the history of the human species, and would carry with it irreversible cascades of species extinctions and significant dangers for human civilization.
What's needed is an immediate reduction of atmospheric carbon dioxide, with the goal of an overall concentration of 350 ppm or less to be achieved as quickly as possible. To accomplish that, the Center supports the rapid phasing out of all coal-fired power plants; the highest technologically feasible vehicle-mileage standards; and a ban on extreme energy development like Arctic drilling, tar sands and fracking, among other critical measures.
