Chevron's Climate Change Perspectives
On the basis of Chevron's Climate Change Action Plan and the Seven Principles on Climate Change, Chevron is working globally to contribute to climate change policy discussions. Chevron's stance reflects a balanced approach to addressing climate change through short- and long-term measures. The collective challenge is to create solutions that protect the environment without undermining the growth of the global economy. From Chevron's perspective, a successful climate policy will be one in which the reduction of GHGs is accomplished equitably by the top emitting countries of the world through long-term and coordinated national frameworks.

Carbon Sequestration
In 2010, Chevron Australia Pty Ltd broke ground on the Gorgon Liquefied Natural Gas Project on Barrow Island, off the northwest coast of Australia. Gorgon includes one of the largest carbon dioxide capture and storage projects in the world. The CO2 present in the natural gas will be injected into a sandstone reservoir more than 1.5 miles (2.4 km) below Barrow Island. This CO2 is extracted from the natural gas as a part of normal gas-processing operations and would otherwise have been vented to the atmosphere. Over the life of the project, approximately 120 million tons of CO2 is expected to be safely injected.
Chevron participates in the Carbon Sequestration Leadership Forum, an international climate change initiative focused on development of improved cost-effective technologies for the separation and capture of carbon dioxide.
In the United States, Chevron is part of the West Coast Regional Carbon Sequestration Partnership, one of seven regional partnerships sponsored by the U.S. Department of Energy.
Energy Efficiency
Chevron has made a long-term commitment to improved energy efficiency its day-to-day operations, which will also help to diminish carbon emissions. Since 1992, Chevron has improved its energy efficiency per unit of output by 33 percent.
Flaring and Venting Reduction
Chevron is working to minimize gas flaring and venting and the GHG emissions that result from this practice. As a member of the World Bank-led Global Gas Flaring Reduction Partnership, Chevron participated in regional workshops that developed country-specific plans to minimize gas flaring. Chevron continues to seek feasible opportunities to reduce flaring and venting in its global operations.
As of early 2010, in Kazakhstan, Tengizchevroil—in which Chevron is a 50 percent partner—no longer flares natural gas except when necessary for safety. Through the four-year, $258 million gas utilization project, gas that previously would have been flared or vented can now be processed for sale or used to support plant operations.
For more than 15 years, Chevron has invested in a series of flare-reduction efforts in Nigeria, including projects that focus on capture and delivery of natural gas from existing flares and others that create the opportunity for previously flared gas to serve new gas markets throughout western Africa. Since 2009, Chevron's offshore Agbami facility has been operating with no routine flaring through reinjection of associated gas, demonstrating the ability to develop new oil production facilities without routine flaring. Chevron continues to work with its production partners in Nigeria on a series of additional projects to address the remaining flares. The third stage of the Escravos Gas Project started up in 2010, increasing the gas processing capability in Nigeria by almost 400 million cubic feet per day (mmcf/d).
In Angola, with completion of the Takula Gas Processing Platform and the Takula Flare and Relief Modifications projects in 2009, routine gas flaring was reduced in the Takula Field by approximately 50 mmcf/d. The Cabinda Gas Plant became fully operational in 2010 and reduced onshore flaring by 3 mmcf/d. The Angola Liquefied Natural Gas facility, which is expected to serve as a future commercial outlet for gas that is currently flared, is scheduled for start up in 2012.
