Eog's approach to reducing greenhouse gas emissions throughout its business is not only environmentally friendly but also a prudent business practice. The company has developed an emissions management system that calculates Ghg emissions from its facilities, based on approved regulatory methodologies and engineering practices. The company reports the emissions for facilities covered by the U.S. Environmental Agency's Mandatory Reporting of Greenhouse Gases Rule, which was amended in 2009 as amended, based on commonly accepted engineering practices.
