To alleviate the pressure on households and businesses in the European Union (EU) caused by the recent energy crisis, EU institutions and Member States have implemented exceptional measures aimed at reducing electricity costs for consumers, and redistributing excess revenue from the energy sector to end customers. At the EU level, these measures have been implemented through European Council Regulation 2022/1854 that establishes a temporary income cap for ‘inframarginal’ electricity producers and a temporary solidarity contribution on windfall profits in the oil, gas, coal, and refining sectors. This goal of this article is to analyse these measures in terms of their impact and alignment with the objectives of the European Green Deal. Specifically, it will examine whether the ‘windfall profit tax for energy providers’ can be considered an environmental tax. Since this does not appear to be the case, the study will also evaluate whether the remaining measures outlined in the regulation can compensate for or mitigate the lack of a true environmental component in the ‘temporary solidarity contribution’. It will assess whether the compensation mechanisms provided by the EU Regulation are sufficient for reconciling the social and redistributive objectives with the environmental objectives of the European Green Deal.
