TLDR: Lighter sustainability-reporting rules are a strategic opening rather than a reprieve, and the companies that win will turn the freed-up compliance budget into AI-driven carbon data that compounds into competitive advantage.
What changed in three months
Between February and April 2026 the rulebook moved twice, and the obligation got smaller. Anyone who spent 2024 and 2025 bracing for mandatory sustainability reporting now faces the opposite problem: deciding what to do with the freed-up effort.
The Corporate Sustainability Reporting Directive (CSRD) was sharply narrowed. The “Omnibus I” package became law as Directive (EU) 2026/470, in force since 18 March 2026, raising the threshold to companies with more than 1,000 employees and over €450M turnover. The Corporate Sustainability Due Diligence Directive (CSDDD) was lifted higher still, to 5,000 employees and €1.5B. Roughly four out of five previously in-scope companies are now exempt from direct reporting.
