Introduction

Advancing Natural Gas STAR International

New Natural Gas STAR International partners include:

Established in 1993, the Natural Gas STAR Program is a flexible, voluntary partnership that encourages oil and natural gas companies—both in the United States and internationally—to adopt proven, cost-effective technologies and practices that improve operational efficiency and reduce methane emissions. Given that methane is the primary component of natural gas and is a potent greenhouse gas—25 times more powerful than carbon dioxide (CO2) in trapping heat in the atmosphere over a 100-year period—reducing methane emissions can result in environmental, economic, and operational benefits.

Natural Gas STAR partners have operations in all of the major industry sectors (production, gathering and processing, transmission, and distribution) that deliver natural gas to end users. Program partners represent 60 percent of the natural gas industry in the United States. Since the inception of the program, these domestic partners have eliminated over 1.15 trillion cubic feet (Tcf) of methane emissions by implementing approximately 150 cost-effective technologies and practices.

With the launch of Natural Gas STAR International (NGSI) in 2006, the Program has expanded to include companies worldwide, significantly increasing opportunities to reduce methane emissions from oil and natural gas operations. Natural Gas STAR International builds off of the framework of the Global Methane Initiative (GMI), an international public-private partnership that advances the cost-effective, voluntary recovery of methane for use as a clean energy source. To date, Natural Gas STAR International partners have reduced methane emissions by 98 billion cubic feet (Bcf).

Together, Natural Gas STAR and Natural Gas STAR International have nearly 130 partner companies—21 of which are international partners. This page highlights the methane emissions reductions that both domestic and international partners have achieved, as well as the variety of technologies and practices they have implemented to reduce methane emissions.

Ongoing Success in the U.S.

Capacity Building Efforts

Many methane emission reduction technologies and practices have become widely implemented as a result of Natural Gas STAR Program events and resources. Recent noteworthy events have included:

During calendar year 2013, 59 percent of U.S. partners submitted an annual report detailing their efforts in 2012 to reduce methane emissions from their operations. These voluntary activities consisted of nearly 50 technologies and practices and resulted in domestic emissions reductions of 66 Bcf for the year. These methane emissions reductions have cross-cutting benefits on domestic energy supply, industrial efficiency, revenue generation, and greenhouse gas emissions reductions. The 2012 emission reductions are equivalent to:

Domestic Emissions Reductions by Sector

The following section illustrates the major sources of methane emissions from each industry sector and the technologies and practices implemented by partners to reduce emissions. The information showing the breakdown of emissions sources was taken from the Inventory of U.S. Greenhouse Gas Emissions and Sinks 1990 - 2011, USEPA, dated April 2013, and the information showing Natural Gas STAR partner activities was taken from partner reports and Natural Gas STAR historical data. The following diagram shows some of the top methane emissions reduction opportunities for each sector.

Natural Gas STAR International

Co-locating GMI Oil & Gas Subcommittee Meeting and Natural Gas STAR Annual Implementation Workshop

A meeting of the Global Methane Initiative’s (GMI) Oil & Gas Subcommittee was held on May 12, 2014 in San Antonio, Texas in conjunction with the Natural Gas STAR’s 19th Annual Implementation Workshop. The meeting focused on GMI and sector-specific activities, the launch of the Climate and Clean Air Coalition (CCAC) Oil & Gas Methane Partnership, and on-going discussions of member experiences while developing Nationally Appropriate Mitigation Actions (NAMA). Presentations focused on the linkages between the subcommittee’s work, advancing development of NAMAs, and other complementary international initiatives and partnerships.

In addition to the success reported under the domestic Program, progress is also being made in reducing global methane emissions through Natural Gas STAR International. International partners reported 7.6 Bcf in methane emissions reductions for a total of 98 Bcf since the inception of Natural Gas STAR International Program. To date, international partners have undertaken methane emission reduction activities in Argentina, Brazil, Canada, Chile, Colombia, Equatorial Guinea, India, Indonesia, Nigeria, Oman, Poland and Qatar. For 2012, these companies reported methane emissions reductions from the implementation of 13 technologies and practices.

The 2012 voluntary international methane emissions reductions are equivalent to:
