Handbook for quantifying direct methane and Non-Methane VOC emissions, Appendix B to guidelines no 044 ver. 17, 23 (2019 updates)

This is an industry document, suggesting best practices in emissions reporting. It reflects Norway's requirements as of 2017 to report "waste gas" emissions of methane and other volatile organic compounds from 32 sources located at oil and natural gas production facilities. The handbook recommends metering vents and tying multiple emissions sources into those vents, to quantify the lost gases. It further recommends the development of facility-specific emissions factors for many sources of emissions, to improve estimates.
