In the global discourse on climate change, an examination of global emissions reveals the substantial footprint of militaries, accounting for an estimated 5% of total emissions. Despite their substantial carbon footprint, defence establishments have been conspicuously absent from discussions surrounding climate mitigation, according to a report by Australian Strategic Policy Institute (ASPI)
Government Commitments and Defence Emissions: Bridging the Gap
While governments pledge to reduce emissions through initiatives like the Net-Zero Government Initiative, defence agencies often remain exempt from such commitments, despite their significant contribution to overall government emissions. However, there is a growing recognition of the need for action, with governments setting targets for emissions reduction within their military sectors.
INNOVATIVE APPROACHES AND CHALLENGES IN DECARBONIZING DEFENSE OPERATIONS
Efforts to reduce defence emissions have seen the emergence of innovative approaches, such as the US Navy’s ‘Great Green Fleet,’ showcasing the feasibility of alternative fuels and energy efficiency measures. Yet, decarbonising defence operations poses formidable challenges, particularly in regions with limited access to alternative energy sources.
RECOMMENDATIONS FOR ACTION: PAVING THE PATH TO SUSTAINABILITY
To catalyze meaningful emission reductions, defence agencies must undertake a series of strategic actions, ranging from measurement and reporting to the integration of sustainability considerations into decision-making processes. Collaboration, knowledge sharing, and investment in low emission alternatives emerge as critical pillars in this endeavour.
EMISSION MEASUREMENT & REPORTING: SHINING A LIGHT ON THE PATH FORWARD
The journey towards emission reduction begins with accurate measurement and transparent reporting. Drawing inspiration from leading examples like the US Department of Defence, enhanced transparency can inform decision-making and inspire ambitious emission reduction efforts.
DEVELOPMENT OF UPDATED SUSTAINABILITY STRATEGY: CHARTING A COURSE FOR CHANGE
Crafting a data-driven sustainability strategy tailored to the defence estate is paramount. This strategy should prioritize projects strategically, aligning with wider policy objectives while minimizing operational impacts.
Embedding sustainability considerations into all facets of defence estate sustainment and investment decision-making processes is essential. Rationalizing the estate for emissions reductions and leveraging frameworks like the National Australian Built Environment Rating System are pivotal steps in this direction.
Prioritizing onsite energy production and storage enhances resilience and reduces reliance on external energy networks. This approach bolsters energy security while mitigating emissions, laying the groundwork for a sustainable future.
EXPLORATION OF LOW EMISSION ALTERNATIVES: EMBRACING INNOVATION FOR A GREENER TOMORROW
Harnessing the scale and expertise of the defence sector, exploration of low emission alternatives such as microgrids and hydrogen technologies holds promise. Investing in innovative solutions paves the way for cost-effective emission reduction.
Maximizing the potential of the defence estate as a platform for emission reduction and offsetting is imperative. Deploying additional energy infrastructure and supporting reforestation initiatives are tangible steps towards carbon neutrality.
Engaging in knowledge sharing initiatives with military counterparts and collaborating with the private sector amplifies the impact of emission reduction efforts. By uniting forces, stakeholders can accelerate progress towards a sustainable future.
