Global Energy Monitor’s Global Gas Infrastructure Tracker (GGIT) uses a two-level system for organizing information, consisting of both a database and wiki pages with further information. The database tracks individual project phases and includes information such as project owner, status, and location. A wiki page for each project is created within the Global Energy Monitor wiki. The database and wiki pages are updated annually.
GGIT includes natural gas transmission pipelines and liquefied natural gas (LNG) import and export terminals. Distribution and gathering pipelines are not included. Historically, a capacity threshold was used for pipeline inclusion, but GGIT now aims to comprehensively track all transmission pipelines longer than 100 km that transport natural gas. We also attempt to track shorter pipelines, especially those that are newly proposed or under construction. No capacity threshold is used for LNG terminals. GGIT only tracks terminals that import or export LNG, and not those used solely for LNG storage or bunkering.
Proposed: A company or government has proposed a project.
Construction: Site preparation or major construction activities have begun.
Shelved: Two years have passed with no development on a proposed project, or it has been announced as shelved. This status is also used for projects that have not begun operations over two years after construction was completed.
Cancelled: Four years have passed with no development on a proposed project, or cancellation has been announced, or the project once appeared in company documents and is no longer in them.
Operating: The project has been formally commissioned; commercial operation has begun.
Idle: The project was at one time operational and now sits unused, but has not been formally mothballed.
Mothballed: The project has been formally taken offline, but not yet decommissioned.
Retired: The project has been decommissioned.
Pipeline and LNG terminal data are collected from and validated through five main sources:
- Government data on individual projects, country energy and resource plans/documents, and government websites tracking project permits and applications
- Reports by state-owned and private power companies
- News and media reports
- Local non-governmental organizations tracking pipelines or terminals, or their permitting process
- On-the-ground contacts who can provide first-hand information about a project
For each project, a wiki page is created on Global Energy Monitor’s GEM.wiki. Wiki pages provide a repository for in-depth information including project background, financing, environmental impacts, public opposition, and routes. Under standard wiki convention, all information is linked to a published reference, such as a news article, company or government report, or a regulatory permit. In order to ensure data integrity in the open-access wiki environment, Global Energy Monitor researchers review all edits of project wiki pages.
Terminal location mapping
If a terminal is in development and not built, the location is estimated based on knowledge of its proposed location or project maps found in research. If it is an expansion of an existing terminal, it is given the same location as the original project. If the terminal is under construction or operating, we attempt to find its exact location based on satellite imagery or documentation. Terminal locations are labeled “approximate” or “exact”.
Pipeline route mapping
Pipeline routes are generated by tracing images of route maps when found in the public domain using QGIS. If no map visual can be found, the route is approximated based on the written information (start and end points, and potential midpoints).
In some cases a route may be missing and the pipeline is absent from the map, but it is still tracked in the database.
As of May 2022, route mapping is prioritized in this way:
- For pipelines longer than 100 km in length, we attempt to have a medium- or high-resolution route. We prioritize pipelines that are proposed, under construction, and operating. If we are unable to find a route map to trace in GIS software, we approximate it, typically with a straight line or a curve with a few intermediate points.
- For pipelines whose lengths are not available from research, we attempt to include at least a low-resolution route in the database and Wiki page, so that we can approximate the pipeline’s length using this route.
- For projects less than 100 km in length, we prioritize mapping routes that have easily available routes online (via maps or shapefiles).
