Pollution incidents and investigations

A pollution incident is when any substance is released to land, air or water that could harm people or the environment. The scope, urgency and organisation of responses to pollution incidents depends on their nature and scale. Major incidents may require a multi-agency response coordinated in accordance with national civil contingency plans and the UK Resilience Emergency Response and Recovery Guidance, involving:

•
police services
•
fire and rescue services
•
health bodies
•
HM Coroner
•
local authorities (LAs)
•
government agencies and other non-departmental public bodies (NDPBs)
•
the Armed Forces
•
the private sector
•
the voluntary sector, and
•
the community

For the most severe emergencies, government may invoke emergency powers under Civil Contingencies Act 2004, Part 2. Emergency powers are a last-resort option for responding to the most serious of emergencies where existing legislative provision is insufficient. They are a mechanism for making temporary legislation in order to prevent, control or mitigate an aspect or effect of the emergency.

The Maritime and Coastguard Agency (MCA) maintains a national contingency plan for marine pollution from shipping and offshore installations.

DESNZ announces approval for Eni's £2bn Liverpool Bay carbon capture project

The Department for Energy Security and Net Zero (DESNZ) has announced that Eni has finalised a £2bn deal for the Liverpool Bay Carbon Capture and Storage (CCS) project spanning north Wales and north west England.

The project aims to create 2,000 construction jobs and will establish infrastructure to decarbonise industries including waste management, hydrogen and cement production. Additionally, the government has announced planning reforms intended to streamline approval processes for clean power projects including solar, wind and nuclear installations.

EBA publishes ESG dashboard for centralised climate risk monitoring in EU/EEA banking sector

The European Banking Authority (EBA) has published an environmental, social and governance (ESG) dashboard designed to provide centralised and comparable climate risk indicators for the EU/EEA banking sector. The dashboard compiles data from information disclosed by banks as part of their Pillar 3 ESG disclosures with reference dates of 31 December 2023 and 30 June 2024, and it forms part of an extensive ESG risk monitoring framework. The dashboard addresses transition risks, which arise from changes in policy, technological shifts, and consumer behaviour, as well as physical risks linked to geographical exposure. It also incorporates indicators for green financing, including metrics associated with the EU Taxonomy and internal assessments such as the Green Asset Ratio, to evaluate exposure levels within banks’ loan portfolios. The EBA intends to update the dashboard regularly in order to reflect revisions in disclosure templates and any regulatory modifications.

HMRC opens technical consultation on draft CBAM primary legislation

HMRC has launched a technical consultation on draft primary legislation for the carbon border adjustment mechanism (CBAM), which will be implemented from 1 January 2027. The consultation, running until 3 July 2025, focuses on technical implementation rather than policy design. The legislation aims to place a carbon price on specified imports from the aluminium, cement, fertilisers, hydrogen, and iron and steel sectors at risk of carbon leakage. The draft includes provisions for registration requirements, tax point determination, compliance mechanisms, and carbon price relief calculations. HMRC has also published accompanying explanatory notes, a tax information impact note, and a policy update to provide clarity for affected businesses.
