The UK offshore oil and gas industry has reduced production emissions by 24% compared to 2018, according to a new report from the leading industry body Offshore Energies UK (OEUK).
In its Emissions Report 2023, OEUK estimates that emissions from the production, transport and processing of oil and gas in the UK fell to the equivalent of 14.28 million tonnes of CO2 in 2022. This compares with the 2018 figure of 18.9m tonnes.
The sector has also halved flaring and venting and cut methane emissions by 45% compared to 2018, demonstrating the sector’s continuous commitment to decarbonisation.
The reductions are in line with the sector’s ambitious commitments under the North Sea Transition Deal, in which the industry committed to reduce emissions 10% by 2025, 25% by 2027, and 50% by 2030.
So far, most of the reductions have been made through operational improvements, process optimisation and the decommissioning of older assets.
The report also shows the UK’s carbon footprint will increase by 50 million tonnes of CO2e by 2050 if there’s no new investment in domestic oil and gas production (the equivalent of the entire UK population flying from London to Glasgow almost 5 times over). This is because the country would become increasingly reliant on imported Liquid Natural Gas, which is often produced and shipped to the UK from countries with less commitment to reducing the environmental impacts of production.
The trade body says in a best-case scenario, where investment in domestic oil and gas production is sustained to prevent a rapid overreliance on imports, the UK industry could still provide 50% of the UK’s oil and gas needs by 2030.
In this scenario, the sector will halve its emissions by 2030, meet net zero by 2050, and continue to support UK jobs and the economy while developing solutions like wind, hydrogen and carbon capture.
Most of the UK sector’s emissions come from generating the energy needed to power offshore installations, including safety systems, plus electricity and heat for the workforce.
Further emissions reductions will increasingly rely on major capital projects, such powering offshore rigs with renewable electricity, known as electrification. OEUK warns these solutions will only be viable with timely access to the National Grid as well as an attractive environment for investors to support the installation of windfarms.
OEUK has laid out four policy actions for government to attract the investment needed to cut emissions and ensure the UK makes the most of its domestic energy resources.
These actions are:
- Make the UK an attractive destination for investment in offshore energy. The Energy Profits Levy casts a shadow on investment and makes it much harder to secure long-term investments in the production assets and infrastructure needed to electrify offshore operations. Decarbonisation mechanisms, now seen as part of the fiscal regime, serve a vital role in facilitating investment across the energy sector, but they are expensive.
- Adopt a whole-system approach to decarbonisation that accounts for upstream and downstream activity, with clear accountabilities for the industry, regulators, and government. This will require alignment between regulatory, government and industry bodies to ensure the decarbonisation of offshore assets is timely, consistent with delivery of emissions targets, and reflects the wider business environment.
- Ensure the UK’s oil and gas production facilities are seen as part of a wider integrated energy system. The remit of “Future System Operator” (FSO) needs to adopt a cross sector approach that aligns with other regulators’ remits. Infrastructure development needs to make the most of the UK’s energy resources both on and offshore to support the growth of the economy.
- Ensure the UK Emissions Trading Scheme (ETS) supports progressive decarbonisation and avoids prematurely shutting down activity. The volatility of the UK ETS scheme has made it harder to plan long term investments.
OEUK sustainability and policy director Michael Tholen said:
“We have a key role to play in helping the UK tackle the energy trilemma: reducing emissions and energy costs while improving the availability of secure supplies of energy.
“The sector has shown continuous commitment to decarbonisation – achieving a third consecutive year of emissions reductions, halving flaring and venting, and cutting methane emissions by 45 per cent in 2022.
“Even though the sector is making big strides, progress is starting to slow. The low-hanging opportunities, like operational improvements and cuts to flaring and venting, having already been achieved.
“Further reductions will now rely on large-scale, capital-intensive projects – so we need to make sure the UK becomes an irresistible place to do business to scale up these solutions.
“Our energy future can be secure, sustainable and provide growth opportunities for UK businesses and people – but only if we have the right support from governments to make the most of our supply chain, skills, and infrastructure.
“The decarbonisation of our sector, and indeed the entire UK economy, will rely on supportive energy policy across the whole energy landscape, so we welcome any action from government that aims to attract investment and accelerate our drive to net zero.”
Notes to editors
Key report findings:
- UK greenhouse gas emissions were 417 million tonnes in 2022, and the offshore oil and gas sector contributed 3.4% of that
- Sector emissions in 2022 were down 24% compared to 2018
- Emissions fell from 18.9mn tonnes in 2018 to 14.28 mn tonnes in 2022, while production increased
- UK gas is up to 4x cleaner than imported gas
- So far operational efficiency and optimisation have done most of the work alongside decommissioning of older assets
- Flaring and venting was reduced by 50%, from 4.62 million tonnes CO2e to 2.32 million tonnes
- Methane emissions have been reduced 45% since 2018
- Methane intensity below 0.2 %, the 2025 target
- Industry has succeeded its 2025 target (10%) three years early
