The IOPER (International Offshore Petroleum Environment Regulators) are a group of regulators who formed in 2013 to focus and drive improvements to environmental performance in the global offshore petroleum exploration and production industry.

Environmental issues, including those associated with offshore petroleum operations, are gaining prominence globally. We believe a collaborative global response to environmental management regulation, and the application of prudent and cautious environmental practices, benefits the offshore petroleum industry, regulators, the public and the environment.
