The Problem (with SPECIFIC evidence)

Every business in the EU that uses words like "eco-friendly," "sustainable," "green," "climate neutral," or "natural" in marketing is about to face a legal reckoning. The ECGT directive (Directive 2024/825) mandates:

  • All environmental claims must be scientifically substantiated with methods like Life Cycle Assessment (LCA)
  • Generic terms ("eco," "green," "sustainable") are banned unless backed by certified outstanding environmental performance
  • Carbon neutrality claims based on offsetting alone are prohibited
  • Independent third-party verification required for labels and claims
  • Fines up to 4% annual turnover or €3.5M

The problem is acute because:

  • Most SMBs have no idea this is coming. A 2025 survey by the European Consumer Organisation (BEUC) found 53% of environmental claims in the EU were vague, misleading, or unsubstantiated
  • Marketing teams write copy without legal review. Every "eco-friendly packaging" claim on a website becomes a liability
  • The compliance process is manual and expensive. Traditional consulting quotes €10K-€50K for a green claims audit
  • Multi-language, multi-market complexity. A Portuguese e-commerce brand selling across the EU needs compliance in potentially 24 languages
