UK approves Jackdaw gasfield in North Sea

The government has approved environmental consent for gas to be produced at Jackdaw, a gasfield in the North Sea. The decision allows the regulator to grant permission for production. It matters because it tests Labour’s promise to move away from new North Sea oil and gas development while maintaining energy supplies.

Jackdaw is owned and operated by Adura, an independent joint venture. Equinor and Shell each own half of Adura. The companies already held operating licences, but their environmental approval was rescinded after a judge ruled that they must include emissions from burning the fuels produced.

The government says Jackdaw will begin supplying homes and businesses from the end of the month. Ministers argue that it will support energy security and reduce reliance on imported fuels. Campaigners disagree and say the field is incompatible with safe climate limits.

Labour’s 2024 election manifesto promised a ban on new drilling licences in the North Sea. Jackdaw can still proceed because its operators already had licences to operate. Their application was for environmental approval, not for a new licence. That distinction allowed the government to consider the project separately from its manifesto commitment.

Adura, the joint venture owned equally by Equinor and Shell, resubmitted its environmental application earlier this year. A judge had rescinded the previous approval because the companies had not accounted for emissions created when their oil and gas were burned. The revised application addressed that legal issue.

The government approved Jackdaw while maintaining that it will end new oil and gas licences. Rosebank, another controversial project, is being decided separately. The approach has pleased industry supporters but caused concern among environmental campaigners and some Labour MPs.

Jackdaw is expected to make a relatively small contribution to national gas demand. Tessa Khan’s campaign group, Uplift, said it would provide around 2% of the UK’s gas demand for roughly 10 years. The oil and gas industry gives a different headline figure, saying Jackdaw and Rosebank could provide 10% of UK output at their peak.

The government gave specific employment figures. Energy secretary Miatta Fahnbulleh said the field would create 27 jobs and secure 273 jobs. She said employment was not the primary consideration in approving the project. Uplift argues that Jackdaw will be largely unmanned and remotely operated, so it will not prevent the wider decline in North Sea jobs.

These figures explain the dispute over scale. Supporters stress energy security and skilled work. Critics say the gas contribution is limited, the field will operate for about a decade, and its economic benefits are overstated.

The government says Jackdaw will begin supplying homes and businesses from the end of the month. Its immediate purpose is to add homegrown gas during winter, when demand for heating and power can be high. Ministers present that domestic supply as a contribution to the UK’s energy security.

Energy secretary Miatta Fahnbulleh said production would help minimise the UK’s use of imported higher-emission fuels. The government has not stated that Jackdaw will replace all imports. Campaigners estimate that it will provide around 2% of UK gas demand for roughly 10 years, so its national effect is limited.

Jackdaw therefore changes the source and timing of part of the UK’s supply, rather than ending dependence on other fuels. The government says this is compatible with its transition to renewables and nuclear power. It also says the field supports a pragmatic path toward net zero by 2050.

Campaigners oppose Jackdaw because producing its gas leads to further fossil-fuel use. They say the climate impact includes emissions from burning the gas, not only emissions from drilling and operating the field. This matters because the UK has legally binding climate commitments and aims to reach net zero by 2050.

A judge previously ruled that the companies had to account for the carbon emissions created when their oil and gas were burned. That ruling forced them to resubmit their environmental applications. Uplift says Jackdaw will provide only around 2% of demand while adding emissions for roughly 10 years.

The wider climate pressure is urgent. The UN Environment Programme says global emissions must be cut by nearly a fifth within four years and close to half within a decade. Campaigners therefore say no new oil and gasfields fit within safe climate limits, even if the government calls Jackdaw temporary.

The article identifies renewable energy and nuclear power as the main alternatives to continued dependence on North Sea gas. The government says it is moving toward both while still expecting oil and gas to meet some energy needs for decades. Replacing gas requires building these lower-carbon sources and connecting them to homes, businesses and industry.

Other established options include improving insulation, using energy more efficiently, and replacing gas heating with electric heat pumps. Expanding public transport and electric vehicles can also reduce fossil-fuel demand outside buildings. These measures are not detailed in the article, but they are widely used ways to lower energy consumption and emissions.

The practical challenge is timing. Jackdaw is due to supply gas this winter, while the transition will take longer. The government plans an energy wealth fund, with a £2bn downpayment, to reinvest oil and gas revenues into the climate transition. Its success would affect future gas demand.

Natural gas is a fossil fuel found underground, made mainly of methane. It is burned to produce heat and electricity. Because it contains carbon, combustion changes that carbon into carbon dioxide. Carbon dioxide traps heat in the atmosphere and contributes to climate change. Gas can emit fewer pollutants than some coal or oil uses, but it is not emissions-free.

The climate effect has two stages. Producing and transporting gas can release methane through leaks, while burning it releases carbon dioxide. Methane is also a powerful greenhouse gas. These emissions add to the atmosphere even when gas is used for a limited period or described as a bridge to cleaner energy.

That is why Jackdaw remains controversial. The government says gas is still needed for decades during the transition to renewables and nuclear power. Campaigners focus on the added emissions and argue that new fields make it harder to meet the sharp global cuts required for climate targets.
