The Oil and Gas Watch database, created by Environmental Integrity Project (EIP), is a free, public-facing tool designed to track the rapid expansion of fossil fuel and petrochemical infrastructure in the United States. Oil and Gas Watch maps new and expanding oil, gas, and petrochemical infrastructure projects across the country and monitors each project’s construction status so the public can stay informed about major oil and gas developments being proposed in their communities. We track key environmental approvals companies must obtain before starting construction or operations and provide access to thousands of government records and permits unearthed by our analysts.
