The aim of this study is to get further insight into climate change impacts on the military activities (infrastructure, installations and equipment) and its coping techniques. A special attention is paid on the decarbonizing potential of the defence forces, which is an important task after setting up the military emissions accounting and reporting system. The research objectives are to answer the following questions: (1) How significant are the climate change concerns for different branches of the military? (2) How viable are the proposed solutions to decarbonize the defence sector and what are the main challenges? (3) What is required to map the carbon emissions and what data is to be collected to get a better view of the carbon emissions trajectory?
