Apache : earns top score in new report on methane management and reporting practices

HOUSTON, Dec. 15, 2017 - Apache Corporation (NYSE: APA) (Nasdaq: APA) earned the top score in Disclosing the Facts 2017: Transparency and Risk in Methane Emissions (DTF 2017), an annual investor scorecard published by As You Sow, Boston Common Asset Management and the Investor Environmental Health Network (IEHN) that ranks the largest oil and gas companies engaged in hydraulic fracturing and horizontal drilling. This year's report exclusively focused on methane management, detection and reporting practices during upstream exploration and production operations. The report graded companies on leak detection and repair (LDAR) programs and methodologies, venting and flaring practices, methane emissions reduction targets and other criteria.

'Apache is committed to the long-term, responsible development of our nation's natural resources,' said John Christmann IV, Apache's chief executive officer and president. 'By collaborating with industry partners and continuously working to improve best practices, Apache has made significant progress toward its goal of reducing methane emissions intensity to 0.36 percent of production or less by 2025.'

Last week, Apache Corporation and 25 other upstream operators joined the American Petroleum Institute's (API) Environmental Partnership, a voluntary program to accelerate the reduction of methane and volatile organic compounds (VOC) emissions during drilling operations.

As reported through the ONE Future Coalition, Apache has reduced its methane emissions intensity by 12 percent from 2015 levels and by 43 percent from 2012 levels.
