Agenda

1. Recap: Methane Satellite Capacity

• EDF satellite mission to produce quantitative data on methane emissions, with a focus on the oil and gas sector
• Launched on March 2024, stopped operations in June 2025
• Intended to cover the gap between point source imagers and global flux mappers (point sources + total emissions)
• Acquired data from ~200x200 km² targets around the planet
• Data products:
• Level 1: top-of-atmoshere radiance
• Level 2/3: XCH4 maps (native spatial sampling or gridded)
• Level 4: total emissions (area+point sources)
• Data available from the public data portal, the Google Cloud, and the Google Earth Engine

The MethaneSAT mission

Partners

A diverse ecosystem of methane-sensitive missions

Area flux mappers (global):

• TROPOMI: 7 km/pixel, global daily coverage, >10 t/h emissions, difficult attribution to sources
• A number of other missions coming up , in particular MethaneSAT (~400 m pixel, 200 km coverage)
• GOSAT-GW, S-5 & CO2M also coming up

Point source imagers (local):

• Spatial sampling ~30 m
• Allow attribution to sources and lower detection limits (300-10,000 kg/h)

Two classes of satellite missions

• Spectrometers (GHGSAt, PRISMA, EnMAP, EMIT): medium-high sensitivity, sparse acquisitions, require tasking
• Multispectral imagers (S-2/Landsat): low sensitivity, but “monitoring” with frequent and global coverage

Sources: Jacob et al., ACP, 2022

• Quantitative data on total methane emissions globally is lacking. Current estimates have large uncertainties.
• MethaneSAT's high precision and wide coverage enables us to see all O&G emissions across basins. This comprehensive data is essential for understanding methane emissions, via 3 scales:

​

MethaneSAT's goal is to quantify total emissions from majority of global O&G production, including large point sources & small dispersed emissions

�3. Uzbekistan Data Insights� Methane Finance Opportunity

Heatmap of aggregated total methane emissions data, summarizing oil/gas and methane intensities

1. Methane is a Material Operational and Financial Issue for Uzbekistan’s Oil & Gas Sector

MethaneSAT Insights for Uzbekistan (July 2024 – June 2025)

• MethaneSAT analysis across eight collections indicates material methane emissions from Uzbekistan’s oil & gas sector, with strong concentration in the Amu Darya Basin.
• Estimated oil & gas methane emissions are ~170 t/h, corresponding to 4.8% methane intensity relative to marketed gas production, with an estimated annual economic loss of $308~880 million*
• Emissions are operationally actionable, with multiple high‑emitting point sources detected.
• Satellite‑derived data provides a credible foundation for operational improvement, inventory strengthening, and methane‑linked finance.

​

Why this matters for Uzbekneftegaz?

• As the largest producer in the basin (~55% share), Uzbekneftegaz can materially shift national outcomes.
• Methane mitigation offers near‑term economic, financial, and reputational upside.
• Uzbekistan transitioned from exporting to importing natural gas since 2023

*Assumptions: Gas unit price based on export opportunity cost to China ($0.40 / m³) or domestic industrial value ($0.15 / m³), continuous leakage (8,760 hours / year)

2. MethaneSAT Provides Decision-Grade, Independent Visibility Across Uzbekistan (July 2024 – June 2025)

MethaneSAT Coverage

• Eight satellite collections between July 2024 – June 2025
• Aggregated regional analysis covering oil & gas production, flaring areas, and surrounding regions

What MethaneSAT Delivers

• High‑resolution detection of area‑wide emissions
• Identification and quantification of large point sources
• Independent, verifiable data aligned with global best practice

Use Cases

• National methane inventory enhancement
• Identification of priority abatement zones
• Evidence base for engagement with financiers, regulators, and partners

​

3. Methane Emissions are Highly Concentrated in the Amu Darya Basin, Linked to Production and Flaring in the South

Non‑Oil & Gas Context

(Bottom‑Up Inventories)

Livestock: 30–70 t/h

Landfills: 4–11 t/h

Southern Uzbekistan (Amu Darya Basin)

Highest methane emissions, Strong correlation with oil & gas production and gas flaring

Eastern & Northwestern regions: Dominated by non‑oil & gas methane (livestock, landfills)

4. Uzbekneftegaz’s Scale (~55% Production Share) Creates Disproportionate Leverage on National Methane Outcomes

Production Landscape

• Total Production: 311 mmboe / yr in 2024
• Uzbekneftegaz: ~55% of basin oil & gas production

Implications for Uzbekneftegaz

• Uzbekistan’s NDC 3.0 (Nov 2025) indicates a 50% reduction in intensity by 2035 vs 2010 baseline.
• Uzbekistan transitioned from exporting to importing natural gas since 2023
• Actions by Uzbekneftegaz can drive disproportionate national methane reductions (O&G contributing to ~70-80% emissions)
• Creates a strong case for leadership in:
• Inventory credibility
• Abatement execution
• Engagement with investors and governments

5. Uzbekistan’s Methane Intensity Is Elevated Versus Many Global Basins

Rapid Reduction in methane intensity is possible and conducive to efficiency gains

6. A Small Number of High-Emitting Oil & Gas Point Sources Offer Immediate, High-Return Abatement Opportunities

MethaneSAT Detections

• Four high‑emitting oil & gas point sources
• Each emitting approximately ~6 t/h
• Co‑located with hotspots identified by other satellites

7. MethaneSAT Enables a Clear Path from Emissions Data to Methane-Linked Finance and Value Creation

• Possibility for favorable (re)financing terms, potentially including a lower interest rate on debt
• Alignment with investor and governmental demands for decarbonization and energy security
• Improvement of underlying asset quality and operations
• Cost effective new gas supply without the new drilling
• Reputational benefits for Uzbekneftegaz and government
• Progress towards corporate and national emissions targets
