Written question asked by James MacCleary (Liberal Democrat) on Monday, 7 September 2026, in the House of Commons. It was due for an answer on Wednesday, 9 September 2026. It was answered by Luke Pollard (Labour) on Tuesday, 15 September 2026 on behalf of the Ministry of Defence.


Ministry of Defence: Climate Change

Question

To ask the Secretary of State for Defence, whether the Ministry of Defence's climate change and sustainability strategy has been updated to incorporate the findings of the national security assessment on global biodiversity loss, ecosystem collapse and national security.

Answer

The MOD's Climate Change and Sustainability Strategic Approach (CCSSA) published in 2021 established a framework for integrating environmental risks into defence planning, infrastructure and operations. In August 2025, the Department endorsed a new internal Energy and Environment Strategic Direction which builds on progress achieved under the CCSSA and which supports policy development in relation to national security assessments of climate change and biodiversity loss and contributions to cross-government initiatives such as the UK's National Adaptation Programme.

These steps support Defence’s move towards warfighting readiness, increased productivity, and responsible environmental action.
