Colorado oil and gas wells can’t fund their own cleanup. Taxpayers may foot the bill | A Carbon Tracker report shows the cost to safely shut down low-producing wells is $3bn more than what they earn
I'm personally working on this problem. It sucks, and the politics are frustrating as hell, but the people working at the State of CO to reign in oil and gas are making every penny of funding work as hard as it can.
I honestly don't really know. I know that The Environmental Defense Fund and The Clean Air Task Force have a strong presence in the state, so it may be worth donating or volunteering for them.
