Contract Negotiation and the Environment: New Tools for Sustainability

The research systematically examines the influence of European environmental law on economic and contractual activities, with particular attention to sustainability, liability, and technological innovation. It reconstructs the framework of principles and sources of European Union environmental law, highlighting the role of secondary legislation and recent directives in the civil, criminal, and administrative fields. Particular emphasis is placed on Directive (EU) 2024/1203, on the regulation of the environmental impacts of extraordinary corporate transactions, and on Environmental Impact Assessment (EIA) under Directive 2011/92/EU. The analysis of the case law of the Court of Justice of the European Union shows how the principles of prevention, precaution, and reparation of damage have acquired a transversal function, significantly affecting corporate liability and national legislative policies. The study also explores the impact of the principle of sustainability in public contracts and consumer contracts, including the evolution of privatization processes, the regulation of public procurement, and the role of Green Public Procurement (GPP) and Minimum Environmental Criteria (CAM) in promoting sustainable production and consumption models. In consumer law, attention focuses on labeling, the environmental compliance of products, warranty systems, and liability, with specific reference to Italian legislation in the wine sector and to European case law on transparency and information. Furthermore, the research develops new models of liability connected to certification systems and emerging technologies. Through the analysis of case law and practical applications, it reconstructs the legal nature of the certifying body’s performance as an autonomous control activity distinct from that of the producer. This leads to a framework of concurrent liability between the producer and the certifying body, aimed at strengthening consumer protection and market safety. The research also highlights the role of new technologies in supporting certification, monitoring production processes, and enhancing environmental compliance. Overall, the study demonstrates how sustainability, from being a programmatic principle, is progressively becoming an operational legal criterion capable of redefining liability, contractual relationships, corporate governance, and the integration of technological tools within contemporary European law.
