NSTA Reports North Sea Emissions Fall for Sixth Consecutive Year

More than half of 2025’s emissions reductions came from action at operating facilities, helping drive a 7% annual decline and a 37% drop since 2018.

In its latest emissions report, the North Sea Transition Authority (NSTA) announced that for the sixth consecutive year emissions in the North Sea have decreased. According to the NSTA, emissions fell by an estimated 7% in 2025, contributing to an overall estimated reduction of 37% since 2018. The NSTA credits strong regulations and industry action for the drop and noted that more than half of last year’s emissions reductions resulted from measures implemented at facilities still in operation, not simply from production shutdowns.

“The North Sea is a vital part of the UK’s energy system, contributing to the transition and many thousands of skilled jobs. It is welcome to see continued impressive reductions in production emissions, reflecting industry work and commitment,” said Hedvig Ljungerud, NSTA director of strategy.

This recent decrease has surpassed the North Sea Transition Deal targets of reducing emissions 10% by 2025 and 25% by 2027, with the NSTA reporting that the goal of halving emissions by 2030 is achievable, based on the current trajectory. More than half of last year’s emissions reductions were attributable to active measures, implemented on installations that remain operational rather than just assets that have stopped producing.

The report also found that the UK’s production emissions intensity was well below the global average, according to Rystad data, driven largely by strong methane emissions performance.

“Looking to the challenges ahead, both future targets and staying globally competitive, the NSTA expects operators to rise to these—as they have many times in the past—and show great urgency in committing to additional, significant efforts across the board to drive down emissions,” said Ljungerud.

Since 2021, the NSTA has issued more than $2 million in fines to operators who exceed flaring and venting volumes. Additionally, the NSTA has promoted investment in equipment to reduce flaring and venting, which it says helped cut overall flaring volumes by 60% between 2018 and 2025, while methane emissions also dropped by an estimated 60% over the same period.

NSTA’s efforts to reduce emissions has received support from the UK government in its November 2025 release of the North Sea Future Plan, which aims to guide the transition from fossil fuels to clean energy while managing existing offshore oil and gas production.
