North Field Expansion and Scope 3: Can Qatar Deliver Low-Carbon LNG?

The Scale of Expansion

Qatar is in the midst of the largest LNG capacity expansion in history. The combined North Field Expansion (NFE) and North Field South (NFS) projects will increase Qatar's LNG production capacity from 77 million tonnes per annum (MTPA) to 126 MTPA by 2027 — a 64% increase that will solidify Qatar's position as the world's largest LNG exporter.

The North Field itself is the world's largest single non-associated natural gas reservoir, shared with Iran (where it is known as South Pars). The field extends over approximately 6,000 square kilometres beneath the Persian Gulf, with estimated recoverable reserves exceeding 900 trillion cubic feet of gas. Qatar has been producing from the North Field since 1997, and the expansion represents a strategic commitment to continue gas production for decades to come.

The total investment in NFE and NFS is estimated to exceed USD 50 billion, involving the construction of six new mega-trains at Ras Laffan Industrial City, along with associated upstream facilities, pipelines, and marine infrastructure. International oil companies — including TotalEnergies, Shell, ConocoPhillips, ExxonMobil, and Eni — hold equity stakes in the expansion projects, underscoring the global significance of the investment.

Decarbonisation Measures: What Qatar Is Doing

QatarEnergy has positioned the North Field Expansion as one of the lowest-carbon LNG projects in the world. Several specific measures support this claim.

Carbon Capture and Storage

QatarEnergy's CCS programme targets capture and storage of up to 11 MTPA of CO&sub2; — one of the largest CCS commitments by any single energy company globally. This includes:

• CO&sub2; capture from acid gas removal units at LNG processing trains, where CO&sub2; is separated from the natural gas stream as part of standard gas treatment
• Compression and pipeline transport of captured CO&sub2; to injection wells
• Storage in depleted reservoirs and deep saline aquifer formations beneath the seabed

When fully operational, the CCS system would avoid approximately 25-30% of the total Scope 1 emissions from LNG production and processing at Ras Laffan. This is a significant commitment, though it is important to note that it addresses only production-phase emissions, not the much larger downstream combustion emissions.

Solar Power for Operations

QatarEnergy has invested in large-scale solar power to partially offset the electricity demand of its LNG operations. The Al Kharsaah 800 MW solar plant, developed as a joint venture with TotalEnergies and Marubeni, provides renewable electricity to the national grid, effectively displacing gas-fired generation. Additional solar capacity is planned to further reduce the carbon intensity of Qatar's industrial energy supply.

Methane Intensity Targets

QatarEnergy has committed to reducing methane intensity across its oil and gas operations to 0.2% by 2025 — among the most ambitious targets in the global industry. This commitment was reinforced by QatarEnergy's signing of the Oil and Gas Decarbonisation Charter (OGDC) at COP28, which includes near-zero methane emissions by 2030.

Methane is particularly important for LNG's climate credentials because it is the primary component of natural gas, and even small leakage rates can significantly erode the lifecycle climate advantage of gas over coal. At current global average methane leakage rates of approximately 2-3%, the climate benefit of switching from coal to gas for power generation is substantially reduced. Qatar's targeting of 0.2% methane intensity — if independently verified — would preserve the majority of LNG's lifecycle advantage.

The Scope 3 Challenge

Here lies the fundamental tension in any "low-carbon LNG" narrative: Scope 3 downstream emissions — the CO&sub2; released when LNG is burned by end users — account for approximately 75-80% of the total lifecycle emissions of an LNG cargo.

Lifecycle Emissions Breakdown

This breakdown reveals a mathematical reality: even if QatarEnergy reduces its operational (Scope 1 and 2) emissions by 50% through CCS and renewables, the lifecycle emissions reduction is only 5-10%. The dominant emissions source — Scope 3 combustion — is beyond the producer's direct control.

LNG vs Coal: The Lifecycle Comparison

The strongest climate argument for LNG is not that it is "low-carbon" in absolute terms, but that it is lower-carbon than coal for power generation. The comparison depends heavily on assumptions about methane leakage and power plant efficiency:

At Qatar's targeted methane intensity levels, LNG produces approximately 50-55% fewer lifecycle emissions than subcritical coal for electricity generation — a meaningful reduction. However, the comparison with renewables makes clear that LNG is a transition fuel at best, not a long-term decarbonisation solution.

"Qatar's LNG can credibly claim to be among the lowest-carbon fossil fuels available. But 'lowest-carbon fossil fuel' and 'low-carbon energy' are fundamentally different propositions. Honest communication of this distinction is essential for credible climate strategy."

Market Dynamics: Who Buys "Low-Carbon" LNG?

The commercial case for reducing the carbon intensity of LNG is strengthening as buyers face increasing climate disclosure requirements and carbon pricing exposure:

• European buyers face EU ETS costs for gas combustion emissions and growing regulatory pressure to reduce imported carbon intensity. The EU CBAM, while not currently covering LNG, signals a direction of travel toward carbon-adjusted trade.
• Asian buyers — particularly in Japan, South Korea, and increasingly China — are implementing carbon pricing mechanisms and corporate climate targets that create commercial demand for lower-carbon LNG.
• Cargo-level emissions certificates: Several initiatives, including the MiQ standard for methane certification, are developing cargo-level emissions certification that would allow buyers to differentiate based on verified upstream and midstream emissions intensity.

Verification Requirements

The credibility of any "low-carbon LNG" claim depends entirely on robust, independent verification of emissions data. As a GAB-accredited verification body, GSustain recognises the critical importance of this verification infrastructure for Qatar's LNG industry. Key verification requirements include:

• Scope 1 verification: Independent verification of direct operational emissions at production, processing, and liquefaction facilities to ISO 14064-3 standards
• Methane measurement: Site-level methane measurements using continuous monitoring, periodic surveys (ground-based and aerial), and reconciliation with satellite data
• CCS monitoring: Verification of CO&sub2; injection volumes, storage integrity, and long-term monitoring of stored CO&sub2;
• Lifecycle assessment: Standardised lifecycle emissions calculation following recognised methodologies (e.g., GREET, GHGenius) with transparent assumptions and third-party review

The Path Forward

Qatar's strategy of combining massive LNG expansion with aggressive operational decarbonisation is internally coherent, even if it does not resolve the fundamental Scope 3 challenge. The key elements of a credible path forward include:

• Transparent reporting: Publishing verified, facility-level emissions data rather than relying on industry averages or favourable assumptions
• CCS delivery: Demonstrating that the committed 11 MTPA CCS capacity is actually built, operated, and verified — not just announced
• Methane excellence: Achieving and independently verifying the 0.2% methane intensity target, using measurement-based (not estimation-based) methodologies
• Demand-side engagement: Working with LNG buyers to develop carbon-differentiated pricing mechanisms that reward lower-carbon production
• Long-term hedging: Investing in technologies — blue and green hydrogen, carbon-neutral LNG offsets, direct air capture — that address the Scope 3 challenge in the longer term

Qatar's LNG will continue to serve global energy markets for decades. The challenge — and the opportunity — lies in making that LNG as clean as possible while the world builds the infrastructure for a post-fossil-fuel energy system. Rigorous measurement, verification, and transparency are the foundation on which any credible low-carbon LNG strategy must be built.
