The world is fighting against the impacts of the climate crisis. Although the technical feasibility of 100% renewable energy systems was already verified by a variety of research studies, there were still more than 200 GW of unsustainable new coal power capacity under construction at a global level in 2018. To achieve the required carbon neutrality, current energy systems need to be transformed toward sustainable energy. The review of the literature has shown that several barriers for carbon-neutral technologies exist, which currently impede the sustainable transition. This paper focuses on the development of an enabling framework to overcome existing barriers to facilitate sustainable and carbon-neutral technologies at the national level. Additionally, it should support decision makers to consider all underlying criteria of this urgently needed energy transition. The criteria of such an enabling framework can be classified in 11 categories, which are (1) environmental and ecological protection; (2) society, culture, and behavior; (3) equity and justice; (4) knowledge; (5) energy markets; (6) energy policy; (7) legal requirements; (8) finance; (9) institutions; (10) infrastructure; and (11) clash of interests. Even though some criteria differ from country to country, a strong governmental support for the transition is always required to be successful.
