Military aggression against Ukraine has had a considerable and lasting impact on the country's economy and led to devastating consequences for the environment and society. Already before the war, Ukraine – like many other countries – was facing significant environmental challenges, including climate crisis and biodiversity loss. Thus, Ukraine has an extremely challenging task – rebuild and restore its infrastructure and economy destroyed by the ongoing war and at the same time continue implementing its sustainability commitments under various international treaties, such as Paris Agreement on climate, and national sustainable development plans.
