Abstract
In recent years, the debate about the role of the Public Institutions in the fields of corporate social responsibility and sustainable development has gained momentum. Nevertheless, the ambiguity of the latter concepts makes it difficult both to measure them and to estimate the impact that the different public initiatives may have on them. In this sense, the present research has the aim to design a fuzzy logic-based methodology applied to the evaluation of the above-mentioned processes in relation to the state-aid policies for the European industry. Regarding the study contour, the European Union state aids seems not to have introduced important changes leading to socially responsible results and, therefore, favourable for the sustainable development generated by the European manufacturing industry
