Repository of Empirical Methane Emissions for Data Integration (REMEDI)

Why REMEDI?

The amount of methane data from satellites, aircraft and ground-based measurements, as well as from industry and regulatory reports is constantly increasing. Yet efforts to effectively track methane emissions are hampered by the fragmentation of available data. Integrating empirical data across scales and technologies is essential to reveal a more accurate picture of emissions, support effective mitigation, monitor progress and drive accountability across sectors.

The integration of methane data starts with compiling fragmented measurement data collected worldwide. Bringing these data into one single repository enables IMEO, as well as scientists and analysts at research institutions, governments and companies to use them in a meaningful way.

Data integration efforts are essential to understand global and regional emission patterns across the full emission spectrum – from small to large emitters, and from point sources to dispersed emissions. REMEDI serves as the central hub for these data, extending beyond and complementing data from the largest super-emitters captured through MARS. Data from MARS and REMEDI also feed into IMEO’s sector specific products, such as the Steel Methane Programme’s transparency database.

What is REMEDI?

REMEDI is a compilation of empirical, geo-tagged and time-stamped methane emission rates based on science-grade measurements. It includes all anthropogenic methane sectors, capturing both point sources (for example, a well site) and area emissions (for example, total emissions from an oil and gas basin). In the oil and gas sector, data cover both site-level and larger scale measurements, meaning that component-level data – such as emissions from a pneumatic device located on a well site – are excluded. Most data in REMEDI originate from scientific field campaigns using fixed monitors, vehicles, drones and aircraft, but the repository also incorporates scientific quantifications of regional total emissions derived from satellite observations.

Each data point is added manually by IMEO’s scientific staff and categorized using a unified data taxonomy that allows users to search and filter data according to their needs. The initial version of REMEDI draws exclusively on data from peer-reviewed literature, but other data streams may be added in the future.

Explore REMEDI

To introduce you to REMEDI, we provide two resources: an overview table and a downloadable sample data set. The table below offers a simplified view of the full repository and includes a subset of parameters that can be used to filter data, for example by region or sector. 

To explore the full data structure and all available fields, download the sample file below.

Help us grow REMEDI – submit your data 

We invite you to submit data from your peer-reviewed publications to help expand and improve the repository. Use the sample data file above as a template to enter your measurements. The template clearly shows which fields are required and which are optional. Completing it may take as little as 5 minutes. 

The sample data file also includes the list of scientific publications currently being analysed by IMEO for inclusion in REMEDI. If your publication is not on the list, please share your data with us. Once you have completed the template, reach out to: unep-methanedataintegration@un.org

Why contribute?

Expose your work

Contributing to IMEO's repository amplifies the impact of your work. As a scientist or empirical data collector, you want your methane data to deliver the greatest possible societal value. This depends not only on citations but also on ensuring that your data informs those with the agency to reduce emissions—such as asset managers in oil and gas companies who take direct mitigation action, and public officials who rely on robust data to track and verify industry reporting.

Once the full REMEDI repository is live on the Eye on Methane data platform, IMEO will use it to generate publicly available, integrated data products tailored to the needs of these and other audiences.

Engage with IMEO

All data in REMEDI are carefully curated and analysed before being added to the repository. IMEO's scientific team reviews every submission and, where needed, extracts methane emission rates and associated metadata – such as location, measurement scope and resolution – into the fixed database structure. We closely engage with our data providers to ensure that the data published in REMEDI, together with any adjustments made to submitted entries, accurately represent the original source data.

Get credit

Funding bodies and other stakeholders increasingly look for evidence of impact beyond scientific publications. Contributing to REMEDI demonstrates your commitment to supporting UNEP’s efforts to mitigate global methane emissions and drive climate action. IMEO will formally acknowledge your contribution and issue a letter recognizing the role of your data in advancing methane mitigation efforts.
