This technical publication analyses why the EU-Mercosur agreement may reduce tariff friction but does not remove the evidentiary burden created by EU product, circularity, carbon, deforestation and supply chain rules. 

It focuses on Brazilian suppliers, the Ecodesign for Sustainable Products Regulation, Digital Product Passport readiness, the Carbon Border Adjustment Mechanism, the EU Regulation on Deforestation-free Products, the Corporate Sustainability Due Diligence Directive and the need to convert operational reality into audit-grade, buyer-readable evidence for European procurement, compliance and board-level review.
