Climate neutrality translates into commitments undertaken by various industries, communities and other stakeholders. The European energy sector is already committed to be carbon neutral before 2050.However, some countries are already fully decarbonised in terms of power generation, while others have to overcome structural preconditions and redefine their entire energy system. For example, Poland is one of the most coal-reliant EU countries, still needing adequate mechanisms to address the challenges ahead.New EU funding under the next Multiannual Financial Framework for 2021—2027 as well as external investment sources bring opportunities for a successful climate transition. Nevertheless, a just energy transition remains a challenge due to the sheer scale of investments required across Europe. Getting the financing right will determine whether emerging business opportunities become socially sustainable and economically viable over time.
