Eighth Report - Defence and Climate Change

The government states that the UK is committed to working with allies in the 'High North' and that the Joint Expeditionary Force (JEF) is already responding to and actively monitoring climate change impacts and security dynamics in the region.

The government details ongoing and planned decarbonisation efforts, including clearing all Defence air platforms for 50% Sustainable Aviation Fuel (SAF) blends, investing £14 million with a further £13 million programmed for Battlefield Electrification trials, and designing future naval platforms for through-life adaptability to new energy sources.

The government detailed extensive ongoing work, including proactive engagement with academia, industry, and allies to assess best practices, and the transfer of assessment tools. It also highlighted existing efforts to reduce carbon emissions, such as the Net Zero Aviation Strategy, fitting new vessels with reduction technology, and investing in Army battlefield electrification.

The government outlines that it has already amended building standards, is undertaking current activities like 'no regrets' asset actions, site-based energy campaigns, solar PV installations, and implementing energy management systems, all contributing to the public sector's Net Zero by 2050 pathway.

The government committed to undertaking a significant accommodation investment strategy review, incorporating Net Zero and energy factors, which is planned to conclude by the end of 2023.

The government has commissioned DSTL to undertake a review of Military Aid to the Civil Authority (MACA) and Humanitarian and Disaster Relief (HADR) activity, due for completion by end 2023. This review will assess historical engagement, future predictions based on climate change, and operational risks, which could inform future discussions on alternative capacity.

The government acknowledges NATO's new methodology for greenhouse gas emissions and commits to remaining actively engaged with NATO initiatives to influence and share experiences on emissions data collection and improvement.

The government stated that military fuel use emissions are already included in the UK's National Atmospheric Emissions Inventory and published in MOD's Annual Report, with the MOD continuing to work on reporting. It also noted that NATO has already published its greenhouse gas emissions methodology, which the MOD actively supports and will remain engaged with.

The government states it already publishes emissions data in its Annual Report and Accounts and re-baselined in FY21-22 to capture more directly influenced emissions, with its methodology verified internally. However, it explicitly states there are no plans to independently verify its emission reporting and it does not currently capture Scope 3 emissions from industrial partners, thus not fully meeting the "total" aspect.

The government explains the discrepancy in reported emissions figures as due to a re-baselining in FY21-22 that expanded the scope of reporting. However, it explicitly states there are currently no plans to return to a stand-alone annual review of its climate and sustainability performance.

The government states that for the 2021-25 Greening Government Commitments, Defence agreed a 10% direct emission reduction target against a 2017-18 baseline. Furthermore, MOD officials are actively working with DEFRA and cross-government colleagues on designing the new set of GGCs for 2025-2030, aiming to shape more effective targets.

The government explicitly states it is not planning on using Science Based Targets (SBT) for Defence, citing potential undermining of capabilities. While major suppliers were already obliged to publish climate reduction plans from September 2021 under PPN 06/21, HMG guidance states SBTs are not aligned with these requirements.

The government states that the Royal Navy is focused on setting ambitious emissions reduction targets for the next 10 years and limiting mid-term impacts. For the Army, further work is required to fully establish operational emissions and carbon sequestration potential, while departmental work on understanding risks and decarbonisation is being further matured.

The government commits to assessing whether Top Level Budget holder and Enabling Organisations' emissions should also be reported as part of the Department’s Annual Reports and Accounts, as part of its ongoing commitment to improve emissions reporting.

The government's response for this conclusion consists only of a page reference and provides no substantive comment on the committee's observation that the dual responsibility of the climate change director may be too distracting.

The government rejects the recommendation to appoint a dedicated climate change director, stating that the existing Levelling Up, Union, Climate Change and Sustainability (LUCCS) Directorate already coordinates these areas, and that combining these responsibilities brings together the three pillars of sustainability within the MOD.
