What will Europe’s environment look like in 25 years? Will we achieve our common vision of ‘living well, within the limits of our planet’? Will we be able to limit global warming and build climate-resilient cities surrounded by healthy nature? Europeans are increasingly concerned as recent European Parliament elections showed. Europe’s next generation is also calling for urgent action, but how will their demands for a sustainable future shape Europe’s environment and socio-economic policies? On our 25th anniversary, we are reflecting on how Europe’s environmental knowledge and policy have developed in the last 25 years and how we, the EEA together with its networks, can support efforts towards sustainability in the next 25 years.
