350 Boulder County wins: 

Located at Dowe Flats, Cemex’s cement Plant is Boulder County’s #1 polluter. Partnering with local coalitions and organizations, in September of 2022 we successfully urged the Boulder County Commissioners to reject the 15-year-extension of Cemex’s plant permit. By doing so, the emission of 5.4 million tons of CO2 into Boulder County’s air has been prevented.

In December of 2020, we succeeded in getting Boulder County Commissioners to pass the strictest oil and gas regulations in the state! This is a huge victory, but there is still a lot of work to be done to ensure a sustainable future for all. We, along with local coalition partners, are continuing calls for a ban on fracking in Boulder County and we hope you will join us in taking action.


Take action now!
