“...Climate change and environmental degradation exacerbate potential conflict, in light of their impact on desertification, land degradation, and water and food scarcity...”

(European Union Global Strategy-2016)

The Energy and Environment Working Group (EnE WG) was formed at the direction of the EDA Steering Board (SB) held on 26 June, 2014. Building on previous work conducted under EDA’s Military Green initiative, EnE WG was formed to take account of the transverse and complex nature of energy and environmental factors in the Defence sector and to offer a structured approach to all aspects of related issues that affect the EDA participating Member States (pMS). The EnE WG is an extrovert scheme, seeking synergies and cooperating with other entities or fora sharing similar concerns (CF-SEDSS, DEFNET, NATO EP WG, etc).


The EnE WG provides capability-aware and strategically informed advice on Energy and Environmental factors affecting the Armed Forces of Europe; delivering tangible benefits in accordance with pMS guidance.


Capability/Research Goals

EDA’s EnE WG is promoting a collaborative and integrated approach to:

  • Examine opportunities to increase the resilience of the EDA participating Members States’ MoDs, Armed Forces and the Defence technological and industrial sector to existing and emerging vulnerabilities resulting from strategic considerations concerning energy security and dependence on fossil fuels, resources security of supply, water security, and environmental change;
  • Explore opportunities to move collectively on a journey towards developing resilient, low-carbon, environmentally sustainable MoD’s and Armed Forces’: by reducing environmental footprints, by realizing the benefits of sustainable resource consumption and production, and by reducing emissions and energy consumption on operations and at home, for sea, land, and air capabilities;
  • Assess the impact of future energy policy on military capability and develop adaptation strategies for alternate fuel and energy sources;
  • Assess the impact of current and emerging global sustainability considerations, including environmental policy, wider geopolitical risks on military capabilities, and develop adaptation strategies;
  • Conduct Technology Watch in support of, for example, military energy efficiency, alternative fuels, power supplies, energy storage, treatment, and reduction of emissions and related control systems developed in full coherence with the Overarching Strategic Research Agenda (OSRA) and associated Technology Building Blocks (TBBs);
  • The Strategic Research Agenda (SRA) was approved by the WG in September 2021. It covers energy and wider sustainability issues of relevance to the planification, development, and generation of military capability;
  • Develop metrics and statistical analysis for energy consumption and related environmental parameters of Europe’s Armed Forces;
  • Improve knowledge dissemination of best practice in the energy and environmental field affecting Defence;
  • Provide collective education and training in priority areas identified by pMS.

A total of ten relevant technological R&T priorities have been identified and translated into Technology Building Blocks (TBB). The Working Group TBBs, as they stand today, are the following:

  • TBB01 - Alternative fuels and drive/propulsion systems
  • TBB02 - Energy storage: electrical, electrochemical, mechanical, structural, and thermal
  • TBB03 - Engine and power distribution system efficiency technologies
  • TBB04 - Energy management technologies: innovative and efficient systems
  • TBB05 - Solar energy generation (thermal and electrical generation)
  • TBB06 - Militarization of environmental technologies: water and wastewater
  • TBB07 - Energy harvesting/scavenging
  • TBB08 - Wind energy
  • TBB09 - Energy and environmental technology systems integration
  • TBB10 - Militarization of environmental technologies: energy from waste (or waste to energy) technologies

EnE Programme Spectrum Of Interest

While the TBBs are orientated to the technology project, the area of interest for the EnE is wider in order to include the environmental perspective, the cultural heritance, consultation and adaptation to policies, and training.

The EnE Programme includes activities related to:

  • Energy Efficiency
  • Energy Performance
  • Renewable Energy Sources
  • Environmental Protection
  • Legislative implications such as the developments in energy and environmental policy and the opportunities and challenges for defence
  • Defence Sustainability and Resilience
  • Sustainable Procurement: Defence Industry Engagement, Supply Chain Security, and Life Cycle Assessment
  • Circular Economy
  • Water Management
  • Waste Management
  • Environment Management Systems
  • Energy Management Systems
  • Energy and Environmental Security
  • Climate Change
  • Knowledge, Culture, and Behaviour
