What Happened
- Satellite data has identified Turkmenistan as the world's top emitter of methane from oil and gas operations, holding 15 of the top 25 methane leak sites globally.
- Some individual sites in Turkmenistan release up to 10.5 tonnes of methane per hour — among the highest single-point emission rates recorded anywhere.
- The findings are significant because Turkmenistan signed the Global Methane Pledge at COP26 (2021), committing to reduce methane emissions by 30% from 2020 levels by 2030.
- Independent satellite monitoring, conducted through platforms such as GHGSat and the MARS (Methane Alert and Response System) digital platform, has revealed a major gap between official national reporting to the UNFCCC and actual emissions measured from orbit.
- The IEA estimates that methane has been responsible for approximately 30% of global temperature rise since the Industrial Revolution, making rapid reduction critical to near-term climate targets.

Global Methane Pledge (2021)
The Global Methane Pledge (GMP) was jointly launched by the United States and the European Union at COP26 in Glasgow, Scotland, in November 2021. It is a voluntary, non-binding political commitment under which signatory countries agree to collectively reduce global methane emissions by at least 30% from 2020 levels by 2030. The pledge is administered under the Climate and Clean Air Coalition (CCAC) framework and aims to eliminate over 0.2°C of warming by 2050.
- Launched: COP26, November 2021, Glasgow
- Core target: 30% reduction in methane emissions from 2020 levels by 2030
- Signatories: Over 159 countries and the European Commission as of 2025 — representing approximately 50% of global anthropogenic methane emissions
- Nature: Voluntary and non-binding; no enforcement mechanism or penalty for non-compliance
- Turkmenistan is a signatory; it also launched a joint project with UNEP in 2024 for methane monitoring via the MARS digital platform
- India has not signed the GMP, citing concerns that natural sources (wetlands, rice paddies) dominate its methane profile and the pledge primarily targets fossil fuel sectors
Connection to this news: Turkmenistan's continued top ranking in satellite-detected emissions — despite GMP membership — illustrates the fundamental weakness of voluntary pledges that lack binding compliance or independent verification mandates.
Methane as a Greenhouse Gas — IPCC Classification and Climate Significance
Methane (CH4) is the second most significant greenhouse gas after CO2 in terms of cumulative forcing but has a far higher warming potential over shorter timeframes. The IPCC's Sixth Assessment Report (AR6, 2021) quantifies methane's Global Warming Potential (GWP) at 84–87 times that of CO2 over a 20-year horizon and approximately 27–30 times over a 100-year horizon (GWP100). Methane's atmospheric lifetime is roughly 12 years, making it a "short-lived climate pollutant" — reductions yield faster temperature benefits than equivalent CO2 cuts.
- GWP (20-year): ~84; GWP (100-year): ~27–30
- Atmospheric lifetime: ~12 years (vs CO2 which persists for centuries)
- Main anthropogenic sources: fossil fuel operations (oil, gas, coal), agriculture (livestock enteric fermentation, rice paddies), waste (landfills)
- Fossil fuel sector: ~35–40% of anthropogenic methane emissions globally
- IEA's Global Methane Tracker monitors oil, gas, and coal methane; UNEP's Global Methane Assessment covers all sectors
Connection to this news: Turkmenistan's oil and gas sector is the source of its record emissions. Because methane warms rapidly over the short term, cutting these leaks could deliver measurable climate benefit within a decade — making the non-compliance especially consequential.
Satellite-Based Methane Monitoring — MARS Platform and GHGSat
Independent satellite monitoring has transformed the ability to hold countries accountable for methane commitments. Technologies like GHGSat (Canadian commercial satellite), Sentinel-5P (EU Copernicus programme), and the MethaneSAT (EDF) can detect large methane plumes from individual facilities. UNEP's Methane Alert and Response System (MARS) aggregates satellite detections and alerts responsible operators and governments in near-real time.
- MARS: UNEP platform launched to operationalise the IEA–UNEP methane monitoring partnership; Turkmenistan partnered with UNEP in March 2024 to receive MARS data
- Sentinel-5P: EU satellite operating since 2017, provides daily global coverage of atmospheric CH4
- Significance for UPSC: Satellite monitoring now creates a parallel verification layer to national inventory reporting under the UNFCCC's MRV (Measurement, Reporting and Verification) system
- India operates RISAT and the NISAR mission (joint NASA–ISRO, anticipated launch 2025) for Earth observation including greenhouse gas monitoring
Connection to this news: The gap between Turkmenistan's UNFCCC inventory submissions and satellite observations exemplifies why the Paris Agreement's Enhanced Transparency Framework (ETF, Article 13) — which mandates improved national reporting — was strengthened under the Katowice Rule Book (2018).
Oil & Gas Methane Partnership 2.0 (OGMP 2.0)
OGMP 2.0 is UNEP's flagship measurement-based reporting framework specifically for the oil and gas sector. Unlike corporate self-reporting, OGMP 2.0 requires company-level reporting based on direct measurement (not emission factor estimates) at five tiers of granularity, making it the most rigorous voluntary standard for sector-level methane accounting.
- Launched: 2020 by UNEP and Climate and Clean Air Coalition
- Participants: Over 70 oil and gas companies covering ~30% of global production
- Five-level framework: moves from Tier 1 (emission factors) up to Tier 5 (site-level direct measurement)
- Turkmenistan's state oil and gas company (Turkmengaz) is not a full OGMP 2.0 signatory, which contributes to data gaps
- Distinction from GMP: OGMP 2.0 is a corporate-level framework; GMP is a government-level pledge
Connection to this news: The lack of mandatory OGMP 2.0 participation by Turkmenistan's state energy company, combined with a non-binding national pledge, creates a verification vacuum — exactly the gap that satellite data has now exposed.
