The International Association of Oil and Gas Producers (OGP) has collected environmental performance information from its member companies on an annual basis since 2001. This programme has continued and new sets of data for activities in 2009 and 2010 have been produced.

The performance information has been collected under the following five categories:

  • Gaseous emissions;

  • Energy consumption;

  • Flaring;

  • Aqueous discharges;

  • Discharges of non-aqueous drilling fluids on cuttings; and

  • Spills of oil and chemicals.

The ultimate aim is to provide a representative statement on environmental performance in the upstream oil & gas industry. Subsidiary objectives are to provide a basis for individual member companies to compare their environmental performance and to demonstrate the industry's wish for greater transparency concerning its activities. This will help them to identify better and more efficient ways of operating.

Performance results are presented on a global and regional basis, onshore and offshore, and normalised to hydrocarbon production. Results are shown, for ease of comparison, alongside the previous years’ published results. The paper will address emerging trends in environmental performance as well as factors that underpin the data.

36 OGP member companies took part in the survey representing about a third of known world production. Contributing companies provided data from 68 countries worldwide; however geographical coverage of the reported data remains uneven, ranging from around 100% in Europe, to 22% of known production in the Middle East and 9% in the Former Soviet Union.
