Europe Gas Tracker Report 2022 methodology
Data sources and methodology
Data sources
The analysis in the Europe Gas Tracker Report 2022 is based on a March 2022 version of the Europe Gas Tracker dataset. See notes on the methodology behind the Europe Gas Tracker at the bottom of this page.
Notes on specific infrastructure projects
- Nigeria-Morocco Gas Pipeline: at the time of writing, this had entered construction, but the sections that terminate in Spain and Portugal were considered proposed.
- Nord Stream 2 Gas Pipeline: at the time of writing, Nord Stream 2 was completed but was considered shelved, as there was no evidence that it would become operational in the near-term.
Pipeline length calculations
Throughout the report, pipeline length plays an important role in extrapolating costs of building pipeline infrastructure. For pipelines that cross national borders, we have calculated the fraction of that pipeline within a given country based on the route that we have in our database. We use the actual pipeline length multiplied by this fraction to calculate kilometers within a given country. If length is not available, we calculate it based on the route alone.
Figures
Figure 1: Estimated cost of future EU gas pipelines and terminals by country
For Figure 1, costs were calculated separately for pipelines, onshore LNG terminals, and offshore LNG terminals.
Costs were reconstructed from totaling pipeline kilometers and LNG import terminal capacity, and using cost estimates as follows:
- An average pipeline cost of €3.42 million per kilometer is assumed for the EU-27 countries; capacity expansion projects, where no new pipeline kilometers are built, are not included in these cost estimates.
- Costs for LNG terminals per unit rate of volume transport are differentiated for floating and onshore terminals.
- For floating (offshore) terminals, a cost of €102.38 million per bcm/y capacity is used
- For onshore terminals, a cost of €184.88 million per bcm/y capacity is used.
Gas pipeline costs
Gas pipeline costs were calculated for each country by dividing estimated costs to build a given pipeline (in €) by the estimated kilometers of that pipeline, then averaged for the full EU-27. Only pipelines that had both a known length and estimated cost in the database were used to calculate costs.
Special cases in the GEM database:
- Adriatica Pipeline: Phases 3, 4, and 5 together cost €1.384 billion; their lengths were totaled (141+174+114 km = 425 km), and this was used as a data point in cost estimates.
- Pipelines that were considered cost outliers and not used in calculations were: Nord Stream Gas Pipeline, Nord Stream 2 Gas Pipeline, and South Stream Gas Pipeline.
Onshore LNG terminal costs
All expansion projects were removed before calculating costs, and a total of 11 projects was used to estimate an EU-27-wide onshore terminal cost of €184.88 million per bcm/y (see table below). This was done by dividing estimated costs to build each terminal (in €) by the total planned or operating capacity (in bcm/y).
Special cases in the GEM database:
- Ravenna LNG Terminal: the cost was estimated at €100 million for a capacity of 0.001 bcm/y; this was considered an outlier and not included in LNG terminal cost estimates.

Offshore (floating) LNG terminal costs
All expansion projects were removed before calculating costs, and a total of 10 projects was used to estimate an EU-27-wide offshore terminal cost of €102.38 million per bcm/y (see table below). This was done by dividing estimate costs to build the terminal (in €) by total planned or operating capacity (in bcm/y).

Figure 2: Historical consumption and future scenarios for EU-27 fossil gas
All data below were converted to units of bcm/y to produce Figure 2. Conversion factors were estimated using BP Statistical Review of World Energy approximate conversion factor tables.
- Historical data (purple line) show EU natural gas consumption combined from the European Commission’s 2020 statistical pocketbook and monthly commodity balance energy statistics from the EC's Eurostat database.
- The EC's statistical pocketbook is only released every two years, and the 2021 version was not available at the time of writing, so we have used the 2020 version which includes data up to 2019.
- To fill in 2020 and 2021, we used commodity balance statistics from the Eurostat database; specifically, we used the "IC_OBS,G3000,MIO_M3" variable within "nrg_cb_gasm" (monthly commodity balance energy data) for each EU-27 member state. At the time of writing (March 2022), 2021 monthly energy data were still not available for Estonia, Netherlands, Greece, Spain, and Croatia.
- IEA scenario (dark blue line) shows projected consumption for the Sustainable Development Scenario from the World Energy Outlook 2021, taken from Table A.12 in Annex A, Tables for Scenario Projections.
- European Network of Transmission System Operators for Gas (ENTSOG, light blue line) is the average of two low-emissions scenarios in Figure 27 of the Ten Year Network Development Plan (TYNDP) 2022 Draft Scenario Report.
- European Commission scenario (green line) portrays the average of three scenarios achieving 55% emissions reductions by 2030, from the 2030 Climate Target Plan.
Figure 3/ES1: EU-27 gas net imports and net import capacity
All data below were converted to units of bcm/y to produce Figure 3. Conversion factors were estimated using BP Statistical Review of World Energy approximate conversion factor tables.
- Historical data (purple line) show historical gas imports inferred by subtracting gas produced from gas consumed within EU-27 boundaries. Gas production and consumption data were taken from the European Commission's statistical pocketbook and country-level datasheets. A 2021 version of the dataset was used, but because the pocketbook provides biannual data, consumption data were only available out through 2019 at the time of writing (March 2022).
- Blue and pink shading show historical and future natural gas import capacity (sum of pipelines and LNG terminals).
- Blue shading until 2021 shows net EU-27 natural gas imports (imports minus exports) from ENTSOG pipeline transmission capacity maps for 2010–2021, plus all historical net LNG capacity (imports minus exports) in the GEM Europe Gas Tracker database. The portion from pipelines was reconstructed by totaling all EU-27 import and export capacities at interconnection points along the borders for each ENTSOG map during 2010–2021.
- Blue shading during 2022 onward shows the total of operating pipeline and LNG terminal capacity (described in the bullet point above), plus any pipelines and terminals in construction as of March 2022, with their capacities being ramped up linearly to reach maximum within five years. These data are from the GEM Europe Gas Tracker database.
- Pink shading shows all proposed gas pipeline and LNG import terminal capacity, with capacities being ramped up linearly to reach maximum within 10 years. These data are from the GEM Europe Gas Tracker database.
- Blue lined section shows the maximum physical transmission capacity of pipelines importing into the EU-27 from non-EU countries along the eastern border. This is meant to represent a conservative estimate of the maximum possible amount of pipeline import capacity possible from Russia (around 247 bcm/y). This was calculated by totaling import capacity, though in practice Russian import volumes are much less, because (1) these interconnection points also carry gas from producers like Turkey and Azerbaijan, and (2) the capacities represent maximum rates of volume that the pipelines can withstand, rather than the actual volumes they carry throughout the year. See the end of this methodology documentation for more discussion on assumptions going into this Russia region in Figure 3.
- IEA scenario (blue dash-dot line) shows inferred net import needs, calculated as the difference between projected demand and EU production for the Sustainable Development Scenario from the World Energy Outlook 2021, taken from Table A.11 in Annex A, Tables for Scenario Projections.
- ENTSOG (blue dotted line) shows the average gas import projections of two low-emissions scenarios in Figure 31 of the TYNDP 2022 Draft Scenario Report.
- European Commission scenario (green dashed line) portrays the average natural gas imports of three scenarios achieving 55% emissions reductions by 2030 from the EC’s 2030 Climate Target Plan.
These calculations assume no retirement of currently operating infrastructure and no new project development beyond what is currently announced.

Balancing issues: EU-27 reliance on Russian gas
Treated as a whole, our findings suggest that EU-27 has sufficient natural gas import capacity if Russian pipeline imports, as measured by the striped region in Figure 3, were removed. However, this carries a few assumptions that should guide its interpretation, on which we elaborate below.
Imbalance in location of LNG import capacity
While EU-27 as a whole may have sufficient gas import capacity to not rely on Russian imports, the majority of this excess import capacity is currently in Spain, and analysis by ING suggests that LNG regasification capacity is already at a maximum in early 2022.
Robustness of EU-27 pipeline network to distribute gas imported from the west
Due to the location of LNG import terminals, the bulk of excess natural gas capacity is in Spain, but there is insufficient pipeline infrastructure to redistribute this gas to the rest of EU-27.
Possible workarounds
There is a possibility that gas could be carried through pipelines of non-EU nations and make up this west–east natural gas capacity imbalance, but there is no clear solution to do this yet.
Using storage better
Another approach would be for EU-27 member states to use natural gas storage better, to buffer against supply shocks, though the issues of import capacity imbalance and east–west distribution would still likely exist to a degree.
Europe Gas Tracker methodology
The Europe Gas Tracker uses a two-level system for organizing information. Summary data is maintained in Google sheets, with each spreadsheet row linked to a page on GEM.wiki. Each wiki page functions as a footnoted fact sheet for a particular piece of infrastructure, containing project parameters, background, and mapping coordinates.
Each piece of information is linked to a published reference, such as a news article, company report, or regulatory permit. For each project, one of the following status categories is assigned and reviewed on a rolling basis:
- Proposed: Projects that have appeared in corporate or government plans, or in news reports, in either pre-permit or permitted stages.
- Construction: Site preparation and other development and construction activities are underway.
- Shelved: In the absence of an announcement that the sponsor is putting its plans on hold, a project is considered “shelved” if there are no reports of activity over a period of two years.
- Cancelled: In some cases a sponsor announces that it has cancelled a project. More often a project fails to advance and then quietly disappears from company documents. A project that was previously in an active category is changed to “cancelled” if it disappears from company documents, even if no announcement is made. In the absence of a cancellation announcement, a project is considered “cancelled” if there are no reports of activity over a period of four years.
- Operating: The project has been formally commissioned or has entered commercial operation.
- Mothballed: Previously operating projects that are not operating but maintained for potential restart.
- Retired: Permanently closed projects.
To allow easy public access to the results, Global Energy Monitor works with GreenInfo Network to develop a map-based and table-based interface using the Leaflet Open-Source JavaScript library, publicly viewable at Europe Gas Tracker.
