Euronext ESG Trends Report 2026: what the data across 1,680 listed companies reveals about the state of European sustainability performance

Euronext's 2026 ESG Trends Report, published during Euronext Sustainability Week 2026, tracks sustainability performance across more than 1,680 listed companies in over 35 countries. The headline figure is a 19% energy efficiency gain recorded across the cohort, alongside measurable progress on emissions reductions and board diversity. The report offers one of the broadest quantitative snapshots of where listed European companies currently stand on sustainability metrics, and its timing during Sustainability Week gives it a platform audience of practitioners and investors.

The report also signals that European sustainability reporting has entered a more complicated phase. Companies across the 35 country dataset are navigating the layering of voluntary frameworks alongside mandatory CSRD requirements, which came into force for large public interest entities for financial years starting 1 January 2024. The coexistence of multiple reporting standards, varying national implementation timelines and evolving ESRS sector specific guidance means that even companies showing strong performance gains face significant disclosure complexity.

For ESG managers and CFOs preparing CSRD aligned reports, the Euronext dataset provides a useful peer benchmarking reference. A 19% energy efficiency improvement across such a large and geographically diverse group sets an implicit market expectation that companies will be able to point to meaningful efficiency progress in their own disclosures. Companies that cannot demonstrate comparable gains will face questions from investors and, increasingly, from assurance providers reviewing ESRS E1 energy intensity disclosures. Automated data collection tools that continuously pull energy and emissions data from operational systems are becoming standard infrastructure for teams managing this kind of ongoing benchmarking exposure.

Board diversity is identified alongside emissions and energy as one of the areas where the Euronext cohort shows measurable gains. For sustainability consultants advising on CSRD readiness, the inclusion of governance data alongside environmental metrics in the same report reflects how integrated ESRS S1 and governance disclosures are becoming in investor analysis. Procurement leads working with listed counterparties should expect sustainability performance data at this level of granularity to increasingly feature in supplier qualification and due diligence processes.

Euronext covers transport networks, energy systems and financial markets infrastructure across its listed universe, which means the dataset includes companies operating across the sectors most exposed to the EU's regulatory transition. The breadth of the 35 country sample also means the report captures performance variation across jurisdictions with different CSRD implementation timelines, providing a useful early signal of where reporting quality gaps are likely to persist as mandatory disclosure requirements extend down to smaller companies in the coming years.
