Feature layer published by the U.S. EPA Landfill Methane Outreach Program (LMOP) that shows landfills listed in the LMOP Database having latitude and longitude coordinates. Data from the LMOP Database are available at https://www.epa.gov/lmop/lmop-landfill-and-project-database.

Web map published by the U.S. EPA Landfill Methane Outreach Program (LMOP) that shows currently operational landfill gas energy projects and landfills listed in the LMOP Database having latitude and longitude coordinates. Data for operational projects are provided in 4 layers by Project Type Category (electricity, direct use, RNG pipeline injection, and RNG local use). Data from the LMOP Database are available at https://www.epa.gov/lmop/lmop-landfill-and-project-database.

Web map published by the U.S. EPA Landfill Methane Outreach Program (LMOP) that shows currently operational landfill gas energy projects and landfills listed in the LMOP Database having latitude and longitude coordinates. Data for operational projects are provided in 4 layers by Project Type Category (electricity, direct use, RNG pipeline injection, and RNG local use). Data for landfills are provided in 3 layers by Landfill Category (candidate, with project, and other). LMOP defines a candidate landfill as one that is accepting waste or has been closed for five years or less, has at least one million tons of waste, and does not have an operational, under-construction, or planned project; candidate landfills can also be designated based on actual interest by the site. Data from the LMOP Database are available at https://www.epa.gov/lmop/lmop-landfill-and-project-database. The Tribal layer data are available at https://geopub.epa.gov/arcgis/rest/services/EMEF/Tribal/MapServer.

The database represents emissions rates quantified by Carbon Mapper across landfills observed and reported in Cusworth et al. (2024). Carbon Mapper leverages hyperspectral imaging spectroscopy to detect, locate, and quantify localized methane emissions. The database contains three sheets: (1) Unique plume detections: this dataset includes individual emission detections (latitude, longitude, emission rate, emission rate uncertainty, datetime) as well as the corresponding landfill’s GHGRP ID. (2) Daily-Average Landfill Emission: daily averaged landfill emissions derived by spatial aggregation and averaging of individual landfill emissions following the methods described in Cusworth et al. (2021). (3) Time-averaged Source List: Average emission rates across all dates of observation. This dataset is associated with the following publication: Cusworth, D.H., R.M. Duren, A.K. Ayasse, R. Jiorle, K. Howell, A. Aubrey, R.O. Green, M.L. Eastwood, J.W. Chapman, A.K. Thorpe, J. Heckler, G.P. Asner, M.L. Smith, E. Thoma, M. Krause, D. Heins, and S. Thorneloe-Howard.
