Tellurian is developing Driftwood LNG and has a guaranteed lump-sum turnkey contract with Bechtel for the terminal's engineering, procurement and construction (EPC). Tellurian has secured all critical Federal Energy Regulatory Commission (FERC) and Department of Energy permits for Driftwood. When completed, Driftwood LNG, with all associated pipeline facilities, will deliver low-cost,low-carbon intensity LNG from the U.S. to help diversify fuel supply and ensure energy security around the world.

Throughout the development process, as part of our risk management discipline, Tellurian teams have been attentive to environmental, social, health and safety aspects of their respective projects. From the earliest stages, they have addressed many elements identified in its designs, policies and operational philosophies where possible. We continue to actively work on mitigations as the development effort progresses.

This approach is in line with and informed by the Equator Principles (EP), a financial industry benchmark for determining, assessing and managing environmental and social risk in projects. We have engaged a consultant to conduct environmental and social due diligence on the project on behalf of future lenders to

ensure alignment with the current EP standards (EP4), published in 2020, and the International Finance Corporation Performance Standards.

Consistent with EP4, we also engaged a third-party consultant to help conduct a Physical Climate Risk Assessment and a Climate Transition Risk Assessment for the Driftwood LNG project, in line with TCFD.

In 2023, Bechtel advanced construction of the LNG terminal. They have driven over 14,000 piles, including all piles for the first plant and substantially completed the piling beneath the two LNG tanks. They have also progressed foundations, including completing the compressor foundations for Plant 1.

Tellurian also has completed all critical owner's projects for the Driftwood terminal, including a pipeline relocation, expanding roadways, adding turning lanes to the local highway, and exercising options on the remaining terminal land leases. Overall, this progress has validated our civil and piling designs with advanced foundation work, readying us for construction ramp-up following a final investment decision.

In 2023, Tellurian secured the FERC certificate for a pipeline project, Lines 200 and 300, and is on track to advance with the fabrication of Baker Hughes zero- emissions integrated compressor line (ICL) compressors for the pipeline. The completion of these ICL compressors is consistent with the LNG project schedule.

UPSTREAM OPERATIONS

Environmental Performance

Air Emissions

Our current operations focus on natural gas development and production within the Haynesville Shale basin in northern Louisiana. The emissions minimizing practices we follow when conducting these operations include:

• Routing gas to production facilities to minimize flaring and/or emissions following well completions
• Performing leak detection and repair surveys utilizing optical gas imaging (OGI) to allow early detection and repairs to minimize emissions
• Deploying technology on new producing facilities that allows for continuous, autonomous methane emissions monitoring to facilitate timely methane emissions management
• Installing electric driven valves and controllers on newly constructed facilities, eliminating

Tellurian incorporates sustainability considerations into the planning and development of our midstream projects.

Minimizing GHG emissions

Pipelines

• Tellurian placed an order for four Baker Hughes' advanced electric-powered compressors in 2022. These drivers will virtually eliminate Scope 1 emissions. The ICL design will eliminate pipelines' fugitive emissions and seal leaks. This will be the first installation of this technology by Baker Hughes in North America.
• We will install GHG emission-free actuators for more than 90% of pipeline valves except for critical service locations, and will perform OGI surveys of transmission and compressor station sites to allow early leak identification, mitigation and repair.

9x Baker Hughes ICL Compressors

• 10+ year maintenance cycle
• >60 installations worldwide
• To be the first in the U.S.

No gearbox

No dry gas seals

LNG terminal

• We will use LM6000PF+ gas turbines, the most efficient in their class to achieve the highest level of reliability, and maximize fully welded pipes to reduce/ eliminate fugitive emissions.
• We maximize welded pipe connections to reduce GHG emissions.
• We will employ truck loading vapor recovery connections to minimize vapor release into the atmosphere and will source all process water from non- potable supplies.

• We designed procedures to assure operational excellence, including a comprehensive leak detection and repair (LDAR) program using drone surveys and OGI.
• We are evaluating advanced process controls to reduce process upsets and improve efficiency.
• We have optimized the boil-off gas (BOG) system to reduce the BOG compressor's electric load, thereby lowering indirect emissions. BOG compressors account for up to 50% of the facility electrical power demand during ship loading.

• The facility will use selective catalytic reduction technology on gas turbines to mitigate nitrous oxide (NOx) emissions.
• All pneumatically actuated valves will be operated with air and nitrogen.
• The LNG terminal is making certain pre-investments to support potential opportunities for permanent geologic
  sequestration of CO2 from the acid gas removal units.

Additional Initiatives to Reduce Emissions Footprint

Driftwood Wetlands Restoration

Tellurian has entered into a memorandum of understanding with Entergy Louisiana ("Entergy") to jointly identify opportunities to develop and potentially deploy technologies that could lead to carbon reductions that support each entity's business objectives. We will work collaboratively to identify opportunities to diversify fuel mix while also supporting and promoting Entergy's development of its green tariff options and identifying strategic partnering opportunities for alternative energy supplies.

Minimizing ecological impacts

Complementing the strong focus on carbon efficiency, Tellurian also seeks to actively manage the ecological impacts associated with our midstream developments.

The construction of the Driftwood terminal will include dredging activities, producing up to 8.6 million cubic yards of permitted dredge spoils.

Coupled with the wetland mitigation requirements of the construction permits, we are committed to the beneficial use of all dredge spoils generated. This has the potential to create the equivalent of four times the amount of wetland habitat than the permitted mitigation requirement, up to 3,000 acres of restored coastal marsh.

These coastal marsh habitats are critical to the environmental health and biodiversity of the Gulf Coast region. They provide shoreline protection from erosion, create buffers from wave action, trap sediment and filtrate water. They provide shelter, food and nursery grounds for coastal

fisheries, birds and animals. The coastal marsh habitat near the project site has degraded over time due to subsidence, water intrusion and development. By repurposing our dredge spoils, this material will re-establish marsh elevations, allowing marsh vegetation to establish and return the areas to their natural and healthy conditions. Once the project is completed, we will monitor the condition and health of the restored marshes to ensure they continue to thrive and are successfully restored.

This is one of the largest privately funded marsh restoration projects in the Gulf Coast area. We enlisted the expertise of Stream Wetland Services, recognized as one of the leading wetland experts in Louisiana, to design the project.

• The LNG terminal site was already zoned for heavy industrial use, consistent with existing industrial and LNG facilities on Louisiana's Calcasieu River, and is being built on land with parcels that had been previously developed for industrial use.
• Line 200 and Line 300 were designed to reduce sensitive habitat fragmentation and minimize overall environmental impacts by routing 83% of the pipeline parallel to existing corridors and will employ construction methodologies to minimize impacts to wetlands and waterbodies.
