Qatar's Updated National GHG Inventory: What the 2026 Data Reveals

National GHG Inventories: Context and Purpose

Every party to the UNFCCC is required to regularly submit national greenhouse gas inventories following Intergovernmental Panel on Climate Change (IPCC) guidelines. These inventories quantify anthropogenic GHG emissions by source and removals by sink across all sectors of the economy. Under the Paris Agreement's Enhanced Transparency Framework (ETF), which became operational in 2024, inventory reporting requirements have been strengthened, with biennial transparency reports (BTRs) replacing the previous biennial update reports for developing countries.

Qatar's national GHG inventory is prepared by the Ministry of Environment and Climate Change (MoECC) using IPCC 2006 Guidelines (with 2019 Refinement for key categories). The inventory covers carbon dioxide (CO₂), methane (CH₄), nitrous oxide (N₂O), hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), and sulphur hexafluoride (SF₆), reported in tonnes of CO₂ equivalent using IPCC Fifth Assessment Report (AR5) Global Warming Potential values.

Qatar's 2026 Inventory: Key Findings

Total Emissions

Qatar's total national GHG emissions for the latest reported year (2024 data, submitted in 2026) are estimated at approximately 120–130 million tonnes CO₂e (MtCO₂e), excluding land use, land-use change, and forestry (LULUCF). Including LULUCF, the net figure is marginally lower, as Qatar's limited forest and vegetation cover provides minimal carbon sequestration.

This represents a modest increase from the approximately 110 MtCO₂e reported for 2019, driven primarily by expanded LNG production capacity (North Field Expansion commissioning) and population growth.

Sector Breakdown

Energy Sector: The Dominant Source

The energy sector (fuel combustion plus fugitive emissions) accounts for approximately 75 per cent of Qatar's total GHG emissions. Within this:

• LNG production and processing: The largest single source category, reflecting the energy-intensive nature of gas compression, liquefaction, and export operations. QatarEnergy's facilities at Ras Laffan Industrial City are responsible for the majority of these emissions.
• Power generation: Qatar's electricity is generated almost entirely from natural gas-fired power plants. Peak summer demand drives high seasonal emissions from the power sector.
• Desalination: Co-located with power generation, desalination is energy-intensive and contributes significantly to the energy sector's emissions profile.
• Transport: Road transport emissions are growing with Qatar's expanding vehicle fleet, though the Doha Metro (operational since 2019) provides some offset for passenger transport.

Industrial Processes

Qatar's industrial sector includes several globally significant facilities:

• Qatalum (aluminium): Primary aluminium smelting produces CO₂ and PFCs from the electrolytic reduction process. Qatalum's capacity of 645,000 tonnes per annum makes it a significant industrial emissions source. PFC emissions (CF₄ and C₂F₆) are particularly potent GHGs with atmospheric lifetimes of thousands of years.
• QAFCO (fertiliser): Urea production involves CO₂ as both a process input and emission. Qatar's fertiliser production capacity of approximately 3.8 million tonnes per annum of urea makes this a material source category.
• Qatar Steel and cement production: Iron and steel production (electric arc furnace) and clinker production for cement contribute CO₂ from both fuel combustion and process emissions (calcination of limestone).
• Petrochemicals: Ethylene, polyethylene, and other petrochemical production at Mesaieed Industrial City.

Waste Sector

Methane from solid waste disposal sites (landfill) is the primary source, with Umm Al Afai and other managed disposal sites contributing. Qatar's waste generation rate of approximately 1.5 kg per capita per day is among the highest globally. The Domestic Solid Waste Management Centre (DSWMC), which includes waste-to-energy and recycling facilities, has reduced landfill methane emissions from new waste streams but legacy emissions from older disposal sites continue.

Agriculture

Qatar's agricultural sector is small but growing under food security initiatives post-2017 blockade. Emissions from enteric fermentation (camels, sheep, goats, cattle) and managed soils (irrigated agriculture) are quantified but represent less than 1 per cent of national emissions.

Per Capita Emissions: Context and Caveats

Qatar's per capita GHG emissions are among the highest in the world, typically reported at 35–40 tonnes CO₂e per person. However, this headline figure requires contextualisation:

• Export-embedded emissions: A substantial share of Qatar's emissions is generated by LNG production for export. These emissions serve energy demand in importing countries (Japan, South Korea, China, Europe) but are attributed to Qatar in the national inventory. If export-embedded emissions were allocated to consuming countries, Qatar's per capita figure would decline significantly.
• Population composition: Qatar's population of approximately 3 million includes approximately 2.5 million expatriate workers. Per capita calculations that divide total industrial emissions by total population can be misleading because much of the emissions comes from large-scale industrial operations serving global markets, not domestic consumption.
• Consumption-based accounting: A consumption-based emissions approach (attributing emissions to the country where goods and services are consumed, rather than produced) would present a fundamentally different picture of Qatar's emissions profile.

Per capita emissions figures are useful for international comparison but can obscure the structural drivers of emissions in small, export-oriented economies. Understanding sectoral detail is more policy-relevant than aggregate per capita figures.

Trends Since Baseline

Qatar's emissions trajectory since its baseline year shows several important trends:

• Absolute emissions growth: Total emissions have increased in line with LNG production expansion and population growth, though the rate of increase has slowed since 2019
• Emissions intensity improvement: GHG emissions per unit of GDP have declined as economic diversification increases GDP faster than emissions growth
• Methane intensity reduction: QatarEnergy's reported upstream methane intensity has decreased from approximately 0.35 per cent (2015) to below 0.2 per cent (2024), reflecting LDAR investment and operational improvements
• Flaring reduction: Gas flaring volumes have declined by approximately 25 per cent since 2015 through improved gas utilisation and vapour recovery
• Power sector efficiency: Combined-cycle gas turbine efficiency improvements and district cooling deployment have reduced power sector emissions intensity

Implications for Corporate GHG Reporting

The national GHG inventory is not just a sovereign accounting exercise. It has direct implications for corporate GHG reporting and verification in Qatar:

Methodological Alignment

Corporate GHG inventories prepared under ISO 14064-1 or the GHG Protocol should be methodologically consistent with the national inventory. This includes:

• Using consistent GWP values (AR5 100-year GWP, as used in the national inventory)
• Applying IPCC emission factors appropriate to Qatar's energy mix and industrial processes, unless facility-specific factors are available and documented
• Ensuring that organisational boundary definitions are clear to avoid double counting or omission relative to the national inventory

Grid Emission Factor

The national inventory provides the basis for calculating Qatar's grid emission factor — the tonnes of CO₂e per MWh of electricity consumed. For corporate Scope 2 reporting (location-based method), this factor is essential. Qatar's grid emission factor is approximately 0.45–0.50 tCO₂e/MWh (reflecting near-100 per cent gas-fired generation), significantly lower than coal-dependent grids but higher than grids with substantial renewable or nuclear capacity.

Scope 3 Context

For companies operating in Qatar's supply chain, the national inventory data informs Scope 3 calculations. Understanding the emissions intensity of Qatar's power, water, transport, and industrial sectors helps companies estimate upstream and downstream value chain emissions more accurately.

Reporting Obligations

As QSE moves toward mandatory ISSB-aligned disclosure, companies will need to demonstrate that their reported emissions are consistent with national methodologies and contribute coherently to Qatar's national inventory. MoECC may eventually require facility-level reporting from major emitters to improve the accuracy of the national inventory — a practice already common in the EU and North America.

How National and Organisational Inventories Relate

The national GHG inventory follows a top-down, sector-based approach using IPCC categories. Organisational inventories under ISO 14064-1 follow a bottom-up, facility-based approach using operational or equity control boundaries. The two should theoretically reconcile but rarely do in practice, because:

• Different boundaries: National inventories use territorial boundaries; organisational inventories use corporate boundaries that may span multiple countries
• Different data sources: National inventories rely on national statistics, industry data, and default emission factors; organisational inventories use facility-specific data, metered energy, and site-specific calculations
• Different purposes: National inventories track sovereign obligations under the UNFCCC; organisational inventories serve investor disclosure, regulatory compliance, and management decision-making

Despite these differences, methodological consistency is important. Companies whose emissions appear in both the national inventory (at sector level) and their own reports (at facility level) should ensure that the methodologies produce compatible results. Discrepancies undermine the credibility of both.

Practical Steps for Qatar-Based Organisations

• Obtain and review the national inventory data: Understand where your organisation's emissions fit within the national picture. This contextualises your reporting and helps identify material emission sources.
• Use consistent emission factors: Align with IPCC 2006/2019 emission factors used in the national inventory unless you have verified facility-specific data that improves accuracy.
• Apply the correct GWP values: Use AR5 100-year GWP values for consistency with the national inventory and current ISSB/GHG Protocol guidance.
• Engage accredited verification: Have your organisational GHG inventory verified by a GAB-accredited body under ISO 14064-3 to ensure data quality and methodological rigour that stands up to regulatory and investor scrutiny.
• Plan for facility-level reporting: As Qatar's regulatory framework evolves, major emitters should prepare for mandatory facility-level GHG reporting. Building systems and processes now avoids scrambling later.
• Connect emissions data to business strategy: Use GHG inventory results to identify reduction opportunities, set science-based targets, and inform capital allocation decisions.

Conclusion

Qatar's national GHG inventory is more than a compliance document for the UNFCCC. It is the definitive account of the country's climate impact and the baseline against which all future progress will be measured. For organisations operating in Qatar, understanding this data — its methodology, its sector breakdown, its trends, and its implications for corporate reporting — is essential for credible climate disclosure, regulatory preparedness, and strategic planning. The organisations that treat the national inventory as a reference point for their own climate accountability will be best positioned as Qatar's regulatory and market expectations continue to tighten.
