| Energy Act 2023 | The Energy Act 2023 improves the resilience and reliability of the energy systems across the UK, to facilitate the delivery of net zero commitments and to increase energy security at a minimum cost to the consumer. In relation to oil and gas activities, this act makes several amendments and provisions, including those relation to environmental protection. These include provisions to enable the Secretary of State to make regulations for oil pollution emergency planning, response and inspection (e.g. delegation of functions, offences, new or amended definitions) and provisions to enable the Secretary of State to make regulations related to habitats regulations assessments, considering the effects on ‘relevant sites’ from oil and gas activities, where a ‘relevant site’ will relate to natural habitats or habitats of species and will be defined in accordance with any proposed regulations. The regulations also include provisions that a licence may not be granted unless the Secretary of State has or Scottish Ministers have carried out an assessment and confirmed that the outcome of said assessment should not prevent a licence from being granted. The Energy Act 2023 (Commencement No. 1) Regulations 2024 brought Sections 296 to 299 (subsections 1 and 2) of the Energy Act 2023 into force on 11th January 2024 allowing for the creation of secondary regulations relating to pollution from oil and gas activities and to establish a charging scheme for the Secretary of State’s functions under Part 4 of the Petroleum Act 1998, in relation to the decommissioning of offshore installations.
