SPECIAL ISSUE (2024) Sustainable Legal Infrastructures: Comparative Responses Across Cultures and Systems edited by Lucia Ruggeri, Lécia Vicente and Sara Zuccarino The Impact of Contractual Energy Sustainability on Vulnerable Persons and on Market Regulation by Manuela Giobbi The relevance of the contract as an effective regulation of the energy market and protection of human rights is being increasingly highlighted.
