In 2007, greenhouse gas emissions from our equity operations were 141 million metric tons. Despite changes in our businesses toward more energy-intensive production, our greenhouse gas emissions (GHG) were reduced by about 5 million metric tons from 2006. About 3 million metric tons of this reduction resulted from efficiency actions taken in 2007, while the balance of the reduction was due to changes in our operations and better GHG emissions measurement in some of our facilities.
Through efficiency actions taken in 2006 and 2007, we reduced GHG emissions by about 5 million metric tons in 2007, equivalent to removing about one million cars from roads in the United States.
Using energy efficiently, investing in technology and promoting access to and global diversity of supplies are vital to long-term energy security.
The latest turbine technology allows cogeneration to be approximately twice as efficient as traditional methods of separate steam and power production.
We continue to implement procedures and projects to improve operations reliability and thereby reduce the flaring associated with unexpected operating events and equipment maintenance.
We are involved in carbon capture and storage projects in several locations.
