Natural Gas STAR International

In 2006, the Natural Gas STAR Program expanded to include oil and natural gas companies throughout the world in support of the Global Methane InitiativeExit EPA Disclaimer. The launch of Natural Gas STAR International significantly increases opportunities to reduce methane emissions from oil and natural gas operations worldwide and creates a framework for global application of the Program's principles including cost-effective methane emissions reduction technology and practice implementation.


EPA estimates that methane emissions from oil and natural gas systems are projected to grow globally by more than 14 percent from 2010 to 2020. (Source: Global Anthropogenic Non-CO2 Greenhouse Gas Emissions: 1990 - 2030, EPA, Appendix B-2, December 2012.)

According to the EPA, Global Anthropogenic Non CO2 Greenhouse Gas Emissions: 1990-2030 report, dated December 2012, oil and natural gas operations are a significant source of global methane emissions, constituting approximately 23 percent of total human-made methane emissions. The report also indicates that in 2010, global oil and natural gas methane emissions totaled approximately 1,677.3 million tonnes carbon dioxide equivalent (MtCO2e). Based on an average natural gas price of $4 (USD) per thousand cubic feet (Mcf), this equates to approximately $16.6 billion (USD) worth of gas lost. Given these results and methane's role as both a potent greenhouse gas and clean energy source, reducing these emissions can have significant economic and environmental benefits.

The United States is a partner in the Global Methane Initiative Exit EPA Disclaimer, an international public-private partnership that advances the cost-effective, voluntary recovery of methane for use as a clean energy source. Global Methane Initiative (formerly Methane to Markets) was launched in November 2004 when 14 national governments signed on as partners. The partnership has since grown to include 40 partner governments and the European Commission and more than 850 public and private sector organizations. Under this framework, EPA launched Natural Gas STAR International, a global partnership with oil and natural gas companies. Natural Gas STAR International [see background document (PDF) (2 pp, 143K, About PDF)] builds on the success of the domestic Natural Gas STAR Program, which has partnered with oil and natural gas companies in the United States since 1993 to promote cost-effective methane emission reduction activities. Natural Gas STAR International Program requirements mirror that of the domestic Natural Gas STAR Program. For additional information on the benefits to participation and company examples, download the Natural Gas STAR International presentation (PPT). (16 pp, 2.6 MB, About PDF)

Membership in Natural Gas STAR International is open to all oil and natural gas companies worldwide. View the current list of companies participating in Natural Gas STAR International. Together, the United States and international oil and natural gas companies are promoting the voluntary implementation of technologies and practices that have been proven to reduce methane emissions from operations.
