People's Petition to Cap Carbon Dioxide Pollution at 350 Parts Per Million

Prominent figures across the country are signing on to this letter to EPA Administrator Lisa Jackson in support of the Center's legal petition, filed with 350.org, to establish national pollution limits for greenhouse gases under the Clean Air Act.

Sign the letter yourself now.


Dear Administrator Jackson:

I support the Clean Air Act petition filed by the Center for Biological Diversity and 350.org to the Environmental Protection Agency to cap atmospheric carbon dioxide levels at 350 parts per million — the level scientists have determined is necessary to sustain life as we know it. 

The Clean Air Act works.  The Clean Air Act has protected the air we breathe for 40 years, reaping economic benefits 42 times its cost.  Today, the Clean Air Act is our strongest tool to immediately curb greenhouse gas pollution and global warming. 

Now more than ever we need you to fully implement the Clean Air Act to protect the air we breathe and preserve a safe climate. I urge you to grant the petition and fully utilize all of the Clean Air Act’s successful pollution reduction programs to achieve the deep and rapid greenhouse pollution cuts needed to protect our future.
