Shut down Suncor's oil refinery injustice

Colorado regulators want to approve a new permit that would allow Suncor Energy to keep polluting at its oil refinery north of Denver, even as the company chronically violates clean air laws meant to protect people and communities. It’s time to put an end to this climate and environmental injustice.

For years, Suncor has violated clean air laws, releasing toxic gases like benzene and hydrogen cyanide. For communities next to the refinery, which are primarily people of color and low-income families, the refinery is an absolute injustice.

Take action today! Sign the petition to ensure Colorado regulators do the right and legal thing by denying Suncor’s air pollution permit.
