Sign our Petition to Stop the Proposed New SDG&E Gas Pipeline!

Sign our petition to call on the California Public Utilities Commission to reject the proposed new gas pipeline that would run through San Diego County, and possibly Mission Trails Park!

The unnecessary and unsafe proposed pipeline would cost ratepayers $600M and would commit us to building new fossil fuel infrastructure when we should be investing in clean energy and green jobs. Sign the petition now, and help us stop this pipeline!
