The International Association of Oil and Gas Producers (IOGP) has collected and published environmental data from its Member Companies every year since 2001. The objective of this programme has been to allow Member Companies to compare their performance with other companies in the sector leading, it is hoped, to improved and more efficient performance. The programme also contributes to the industry’s wish to be more transparent about its operations. The analysis summarises information on exploration and production (E&P) activities carried out by contributing IOGP Member Companies in 2022. Environmental information is collected for the following categories: Gaseous emissions Energy consumption Flaring Produced water discharges Non-aqueous drilling fluids retained on cuttings discharged to sea Oil and chemical spills Fresh water withdrawn for use Data are collected annually for each of the categories above, on the basis of a set of definitions agreed by the IOGP Membership. These definitions align with Ipieca-API-IOGP Report 437 - Oil and gas industry guidance on voluntary sustainability reporting
