New UK Offshore Oil & Gas Environmental Rules Explained

UK Overhauls Offshore Oil and Gas Regulations to Include Downstream Emissions

In a significant shift for the UK's offshore oil and gas sector, new guidance has been introduced that mandates the consideration of 'downstream' or Scope 3 emissions within the consenting process for new projects. This means that the environmental impact of using or burning the fuels extracted will now be a key factor in decisions regarding the approval of offshore developments. This move follows a landmark Supreme Court ruling that highlighted the need to account for the full environmental consequences of fossil fuel extraction.

Understanding the New Guidance: Scope 3 Emissions at the Forefront

Previously, environmental impact assessments for offshore oil and gas projects primarily focused on the direct emissions generated during the exploration, extraction, and production phases. However, the new guidance, announced by the UK's Department for Energy Security and Net Zero, explicitly incorporates Scope 3 emissions. These emissions, which occur when the extracted oil and gas are used and combusted, have long been a point of contention for environmental campaigners. By including them, the government aims to provide a more comprehensive and accurate assessment of a project's overall environmental footprint. This ensures that the full effects of fossil fuel extraction on the climate are recognised in consenting decisions, aligning with the UK's target to reach net zero emissions by 2050.

The Legal Precedent: The Finch Supreme Court Judgment

The impetus for this regulatory change stems from a crucial ruling by the UK's Supreme Court. In January, the court declared the approval of two North Sea projects – Shell's Jackdaw and Equinor's Rosebank – unlawful, stating that the environmental impact of burning the extracted fossil fuels had not been adequately considered. This judgment mandated that the approval processes for these projects must be retaken, incorporating the assessment of these so-called 'downstream' emissions. Consequently, developers of these projects, along with others, have been awaiting the new guidance to reapply for consent.

Industry Response and Project Implications

Companies involved in these major North Sea projects have reacted to the new guidance. A spokesperson for Shell stated that the company is reviewing the guidance and remains committed to delivering the Jackdaw project. Similarly, Equinor and Ithaca Energy, involved in the Rosebank project, have affirmed their focus on advancing it, with Equinor indicating its intention to submit an assessment under the new framework. The new guidance provides a clearer pathway for these companies to resubmit their applications, albeit with the added requirement of addressing Scope 3 emissions. The Energy Minister will now be tasked with evaluating these applications, considering their compatibility with the new guidance and the UK's climate targets, with decisions expected in the autumn.

Broader Context: Net Zero Targets and Energy Security

This regulatory update is set against the backdrop of the UK's ambitious net zero emissions target by 2050. While the government has previously committed to not issuing new oil and gas licences, it has also acknowledged the continued role of oil and gas in the country's energy mix for the foreseeable future. Energy Minister Ed Miliband has often spoken about the necessity of reducing reliance on fossil fuels to drive down costs and enhance energy security. This new guidance represents a balancing act, ensuring that while fossil fuel extraction continues, its environmental consequences are more transparently assessed and managed. Environmental groups, such as Greenpeace and Uplift, have welcomed the changes, with Uplift's executive director, Tessa Khan, stating that companies will now be "forced to come clean over the enormous harm they are causing to the climate."

The Evolution of Environmental Impact Assessments (EIAs) in the UK

The introduction of Scope 3 emissions into the consenting process marks a significant evolution in how environmental impacts are assessed for offshore projects. The Offshore Oil and Gas Exploration, Production, Unloading and Storage (Environmental Impact Assessment) Regulations 2020, which came into force immediately before 11 p.m. on 31st December 2020, provide the legislative framework for these assessments. These regulations replaced earlier legislation, consolidating and updating the requirements for environmental impact assessments in the offshore sector. They mandate a rigorous process, including the preparation of an environmental statement, public consultation, and consideration by the Secretary of State, who must agree to the grant of consent before the Oil and Gas Authority (OGA) can issue it. The inclusion of downstream emissions is a direct response to evolving scientific understanding and legal interpretations of environmental responsibility.

Key Components of the New EIA Regulations

The 2020 EIA Regulations detail a comprehensive process for assessing the environmental impact of offshore projects. Key elements include:

• Requirement for Consent: Developers must obtain the Secretary of State's agreement to the OGA's grant of consent before commencing a project.
• Environmental Impact Assessment (EIA): Projects falling under Schedule 1 of the regulations automatically require an EIA. For projects in Schedule 2, a screening direction is needed to determine if an EIA is necessary, or the developer can opt for an EIA. Schedule 3 projects do not require an EIA unless the Secretary of State deems it necessary.
• Environmental Statement: This is a crucial report prepared by the developer, detailing the likely significant effects of the project on the environment, including the new consideration of Scope 3 emissions. It must be prepared by competent experts.
• Public Consultation: A vital part of the process, ensuring that authorities, stakeholders, and the public have the opportunity to comment on the environmental statement and the proposed project.
• Secretary of State's Decision: The Secretary of State must consider the environmental statement, representations received, and any further information before deciding whether to agree to the grant of consent. This decision includes an explanation of how environmental effects have been taken into account and may include conditions to mitigate adverse impacts.
• OGA's Decision: Following the Secretary of State's agreement, the OGA makes the final decision on whether to grant consent.

Environmental Risks Associated with Oil Drilling

The environmental risks associated with oil drilling are multifaceted and can have profound impacts on ecosystems and human health. These risks, which the new regulations aim to better address, include:

Oil Spills and Their Devastating Consequences

Oil spills, such as the infamous Deepwater Horizon incident, release crude oil into the environment, causing immediate and long-term ecological damage. Marine life, from plankton to whales, can be directly affected, leading to habitat degradation, disruption of food chains, and potential extinction of vulnerable species. The cleanup process is often lengthy and costly, with some ecosystems taking decades to recover, if at all. The new regulations, by considering the full lifecycle emissions, indirectly acknowledge the inherent risks associated with the very product being extracted.

Habitat Destruction and Biodiversity Loss

The physical footprint of oil drilling operations, including the construction of platforms, pipelines, and associated infrastructure, can lead to the destruction and fragmentation of natural habitats, both on land and at sea. This disruption can displace wildlife, reduce biodiversity, and impact breeding patterns. The noise and light pollution generated by drilling activities can further stress wildlife, interfering with communication, migration, and foraging behaviours. Protecting biodiversity is a key concern addressed by environmental impact assessments.

Water and Soil Contamination

Beyond accidental spills, drilling operations can lead to the contamination of water and soil through leaks from equipment, improper disposal of drilling fluids, and the management of produced water. These fluids often contain heavy metals and other toxic chemicals that can seep into groundwater and surface water, posing risks to aquatic ecosystems and potentially entering the human food chain. Soil contamination can render land unusable for agriculture or natural vegetation, with long-lasting effects.

Climate and Atmospheric Impact

The oil and gas industry is a major contributor to climate change. Greenhouse gas emissions, primarily carbon dioxide (CO2) and methane (CH4), are released during extraction, processing, and transportation, and most significantly, during the combustion of the fuels themselves. Methane, in particular, is a potent greenhouse gas with a high short-term warming potential. Air pollution from drilling activities, including nitrogen oxides and particulate matter, can also have detrimental effects on local air quality and human health. The inclusion of Scope 3 emissions directly addresses the atmospheric impact of burning the extracted fuels.

Mitigation and Management Strategies

To address these environmental risks, a range of mitigation and management strategies are employed, and are now being more rigorously scrutinised under the new regulations:

• Environmental Impact Assessments (EIAs): As discussed, these are fundamental to identifying and assessing potential impacts and proposing mitigation measures.
• Spill Prevention and Response: Robust measures are in place to prevent spills, including advanced technology and stringent operational protocols. Comprehensive spill response plans are also critical for minimising damage should an incident occur.
• Sustainable Drilling Practices: The industry is increasingly adopting more sustainable practices, such as using less water, minimising land disturbance, and exploring technologies like carbon capture and storage (CCS) to reduce emissions.
• Waste Management: Effective management and disposal of drilling waste and produced water are crucial to prevent environmental contamination.

The Future of Offshore Oil and Gas in the UK

The new guidance and updated EIA regulations signal a more stringent approach to environmental oversight in the UK's offshore oil and gas sector. While the industry continues to play a role in the UK's energy supply, there is a clear and increasing emphasis on understanding and mitigating the full spectrum of its environmental impacts, particularly in relation to climate change. This regulatory evolution reflects the growing global awareness of environmental issues and the imperative to transition towards a cleaner energy future. Developers must now navigate a landscape where not only the extraction process but also the ultimate use of the extracted resources are subject to environmental scrutiny, ensuring greater accountability and a more informed approach to energy development.
