Abstract
This study aimed to identify the specific features of the institutional and regulatory changes that took place in Argentina, Brazil, Paraguay and Uruguay as a response to the European Union’s greening of its market-access conditions, considering the countries’ own adaptation mechanisms, the interregional agreements and the multilateral trade-law context. The study used structural-functional analysis, comparative analysis, documentary analysis, comparative-legal analysis and formal-legal analysis. Its findings indicate that the European Green Deal has extended its environmental and climate requirements to the conditions governing access to the European Union market, since deforestation requirements connect market access with traceability and the Carbon Border Adjustment Mechanism does the same in relation to emissions accounting and verification. In Argentina, traceability and certification are being introduced to meet the demands of deforestation; in Brazil, agricultural data is being integrated; in Paraguay, digital traceability is being implemented, and in Uruguay, product verification is being carried out. Nevertheless, national carbon-policy mechanisms are being developed as well, even though no direct documented link has been found between these mechanisms and the Carbon Border Adjustment Mechanism. In Argentina and Brazil, debate centres on the trade consequences of the requirements, the costs of complying with them, and the recognition of national control systems. The negotiations carried out between 2023 and 2024, along with the legal formalisation of the agreements in 2026, clarified the climate provisions, the commitments relating to deforestation, and the position taken with regard to the Paris Agreement. The treaty obligations, the European Union’s autonomous rules and the rules of multilateral trade law together constitute a multi-layered trade-law architecture. The greater the structure of exports, the more important traceability becomes, whereas alternative markets reduce the uniformity of the regulatory impact. It is therefore concluded that the European Green Deal functions as an external regulatory stimulus causing institutional adaptation, and the way this adaptation is manifested at the national level should be examined in view of the institutional and sectoral context, the export structure and the role of the European market. The importance of the findings is that they can be made use of by public authorities and participants in foreign trade in the European Union partner countries when improving the mechanisms, they have for meeting the environmental and carbon requirements of the European market and for drawing up their negotiating stances on market-access conditions
