Shell has submitted an updated emissions statement for its Jackdaw gas field, asserting it would produce significantly lower greenhouse gas emissions compared to other sources. The statement, released following a court's quashing of the original development consent for failing to assess Scope 3 emissions, is part of Shell's bid to secure new approval for the project.

Emissions Performance and Comparison

According to Shell's report, the Jackdaw field's emissions intensity is estimated at 8.5 kilograms of CO2e per barrel of oil equivalent, which is less than half the UK average of 18 kg CO2e per boe. Furthermore, Shell claims that gas produced from Jackdaw would generate less than one-tenth the emissions of the average liquefied natural gas (LNG) imports into the UK. Total Scope 3 emissions over the field's life are projected to be 35.8 million tonnes of CO2e under a maximum production scenario and 23.6 million tonnes under a "likely production" scenario.

Strategic Importance and Infrastructure

Shell emphasizes that the Jackdaw project is critical for sustaining UK strategic energy infrastructure. Production from Jackdaw is intended to help keep operational key shared assets, including the Shearwater hub, St Fergus terminal, and the SEGAL system, which collectively process around one-third of the UK's gas demand. The field is projected to reach a peak production of 40,000 barrels of oil equivalent per day, equivalent to about 6.5% of UK Continental Shelf production, with startup targeted for the third or fourth quarter of 2026.

Regulatory and Political Context

The approval for the Jackdaw field now rests with UK Energy Secretary Ed Miliband, and the industry is closely watching the government's decision. This comes amid election campaign pledges to ban new licenses and work towards net zero emissions. The UK's carbon budget, designed to keep the country on track for its 2050 net zero target, assumes continued demand for gas, whether imported or domestically produced.

Support and Opposition

Offshore Energies UK, a trade lobby, welcomed the emissions statement as an "important milestone," arguing that with the right policies, the North Sea's energy mix can remain a strategic national asset. In contrast, Greenpeace UK, which originally challenged the development consent, criticized the project, stating that the revealed scale of pollution makes it a "dud project for the UK" and that approval would benefit Shell at the public's expense, contributing to extreme weather events.

Global Emissions Impact and Project Status

Shell's report indicates that the field's emissions would represent a very small proportion of projected global emissions in 2030 and 2035 and would not significantly affect the world's ability to meet Paris Agreement targets. Shell has invested over £1 billion in the field, which features a "not permanently attended" wellhead platform with four wells tied back to the Shearwater hub, and project execution is reported to be around 90% complete.
