The International Offshore Petroleum Environment Regulators (IOPER) is a collaborative group of national regulators whose members are dedicated to raising environmental performance standards within the offshore petroleum exploration and production industry.

This includes standards applicable to the industry's normal operations, as well as environmental emergency prevention, preparedness and response.

Many members of the IOPER also have an association with the International Regulators Forum for Global Offshore Safety.

Members of IOPER progressed discussions on key issues facing regulators and made good progress on a number of key priority issues at the 2014 annual general meeting in Cancun, Mexico. The meeting was hosted by IOPER’s newest member - the Mexican offshore petroleum regulator, National Agency for Safety, Energy and Environment of Mexico (ASEA).  IOPER members met to provide updates and discuss emerging issues in their jurisdiction. A refinement of IOPER’s work program was also agreed to focus on 5 key priority issue areas:

  • Environment Performance Indicators
  • Regulating Oil Spill Preparedness and Response
  • Public Consultation and Decision Making
  • Environmental Impact Research Collaboration Opportunities
  • Enforcement Tool Research
