Sunoco named as the least evil gas refiner and seller. Greenopia, Green America, and Sierra Club, over the last few years have looked into this, and determined that Sunoco is not a climate denier, they voluntarily comply with a code of environmental conduct called CERES Principles, don't seem to hate hippies.
They are not a green company, they don't promote bikes and EV's. But within their market they are the least evil.
None in my area, I see them sometimes on trips, will buy from them next chance.
