Key Facts
- •The case concerns the statutory process for achieving net-zero greenhouse gas emissions by 2050 under the Climate Change Act 2008 (CCA 2008).
- •Claimants challenged the Secretary of State's Carbon Budget Delivery Plan (CBDP), arguing non-compliance with sections 13 and 14 of the CCA 2008.
- •The CBDP aimed to meet Carbon Budgets 4, 5, and 6 (CB4-CB6), with a focus on CB6 (2033-2037).
- •The Secretary of State's decision relied on quantified and unquantified proposals and policies, with significant reliance on the assumption that all quantified proposals would be delivered in full.
- •The Claimants argued the Secretary of State failed to adequately consider delivery risks, particularly through the absence of individual policy RAG ratings in the briefing materials.
- •The Claimants also challenged the adequacy of the CBDP's information on sustainable development and its compliance with section 14 reporting requirements.

Outcomes
The application for judicial review is allowed on Grounds 1, 2, 3, and 4.
The Secretary of State's decision was based on an irrational assumption that all quantified proposals would be delivered in full, without adequate consideration of individual policy delivery risks. The assessment of sustainable development also fell short of the statutory requirement.
Ground 5 is dismissed.
The CBDP complied with the Secretary of State's duty under section 14 of the CCA 2008, as it provided sufficient information to Parliament on the proposals and policies for meeting carbon budgets. The court did not find an obligation to include granular risk data for individual policies.
