Holding corporations accountable for ‘zombie wells’

Fossil fuel corporations have left a haunting legacy of over two million polluting abandoned oil and gas wells across the United States. These "zombie wells" are disastrous for the climate, bad for human health, and a financial burden on US taxpayers.

Read more below about our two actions in the US:

ClientEarth class action case in Colorado

Americans stuck with polluting abandoned wells on their property are asking the court to hold previous well operators responsible for the clean-up in a landmark lawsuit that could set a new precedent for polluter accountability. 

A group of property owners and farmers in Colorado, burdened with polluting abandoned oil and gas wells on their properties, have filed a lawsuit against oil and gas companies in a landmark case that could dramatically overhaul responsibility for the nation’s more than two million unplugged oil and gas wells.

The plaintiffs’ class action complaint alleges the oil and gas companies took part in common oil industry tactics to evade their legal responsibilities to ‘plug’ the wells once they have stopped producing oil or gas.

Plugging is a critical process that involves securely sealing the well to prevent harmful pollutants from escaping into the environment and to reduce contamination risks.

The claimants are represented by ClientEarth US.

Take action: send a letter to Chevron

Chevron is responsible for many of the millions of unplugged oil and gas wells in the US. These so-called ‘zombie wells,’ are leaking methane at a dangerously high rate, spewing harmful toxic chemicals that threaten wildlife, people, and our environment.

Urge the company to keep its promise and clean up its toxic mess.
