Disclosing the Facts 2017: Transparency and Risk in Methane Emissions is an investor report designed to promote improved methane management and reporting practices among oil and gas producers. This report is both broader and more limited than prior Disclosing the Facts reports. Prior DTF reports have focused on best practices across a range of risk areas (chemicals, air, water, community impacts) by oil and gas companies engaged in horizontal drilling and hydraulic fracturing in the United States and Canada. While Disclosing the Facts 2017 focuses on a single issue -- methane emissions management -- the report does not limit its focus to fracturing operations in unconventional resources. Since methane emissions can occur across unconventional and conventional upstream exploration and development, this full range of operations is included.
