This paper aims to analyse European climate policy’s state of the art concerning the urgent need to decarbonize society and the economy and meet pressing climate demands. Decarbonization refers to the progressive reduction of the carbon-to-hydrogen ratio within energy sources. The primary objective consists of a gradual transition to sustainable economic less polluting development models. The Paris Agreement (2015) highlighted the need to take concrete and timely action to prevent the planet’s already precarious balance from definitively collapsing. This paper analyses the main strategies that the European Union has conducted to take an active part in the decarbonization project by critically highlighting the challenges and opportunities that await us in the future.
