Description
Environmental Defense Fund’s (EDF’s) Permian Methane Analysis Project (PermianMAP) was a monitoring and research project to provide transparent and accessible methane emissions data from one of the world’s largest oil fields. The project was designed to use a variety of peer-reviewed techniques to monitor and quantify emissions, including: satellite-based regional estimates; ground-based vehicle measurements and helicopter-mounted optical gas imaging; stationary measurement towers and periodic aircraft mass balance flights; and aircraft hyperspectral imaging. This case study presents these monitoring efforts and discusses how resulting data was made available on a public website within days to weeks after data collection.
