Download methane city data
The data sets available were used to create the maps and graphics on these web pages. It is important to note the following:
- These data represent leak indications identified during the specific dates of our survey efforts and subsequent analysis by EDF and Colorado State University (CSU). They are not meant to represent real-time, complete, or current leak inventories, which are constantly changing due to repairs, environmental conditions, etc.
- These maps and datasets may be periodically updated. Please check this page to access the latest available versions.
The data comes in excel file (.xls) and shapefile formats (.shx, .shp, .sbx, .sbn, .prj, .dbf, .cpg). The information for each point includes 1) latitude and longitude, 2) category, 3) ID number and 4) first and last date observed. The methodology and algorithm developed by CSU for this project have been published in a peer-reviewed paper in Environmental Science & Technology.
