Climate change is one of the defining issues of our time and also for the defence and security sectors. We know that militaries are a heavy polluter and they are even defined by some as significant contributors to climate change. In this final episode of the series, we ask Maja Kuzel, EDA's Project Officer for Energy Support, and Constantinos Hadjisavvas, Project Officer for Energy, how EU defence can become greener, less polluting, and help build a more sustainable future for all.
