EU Adopts Revised ESRS — 70% Data Point Reduction, 30% Cost Savings, Voluntary Standard for Smaller Companies

On July 3, 2026, the European Commission adopted the revised European Sustainability Reporting Standards and a parallel voluntary standard for companies outside the CSRD's scope. The revised ESRS reduces mandatory data points by over 60%, total data points (including voluntary) by over 70%, and is projected to reduce per-company reporting costs by over 30%. Wave 1 companies — those with more than 1,000 employees and over €450 million in turnover — may choose to adopt the simplified standards, continue reporting under the existing ESRS, or apply a hybrid approach during the transition period. Critically, the voluntary standard introduces a "value-chain cap" preventing CSRD-in-scope companies from requiring value-chain partners (suppliers, customers) to provide information beyond what the voluntary standard covers — a provision directly relevant to the large number of mid-sized firms currently receiving CSRD-driven questionnaires from their larger clients. Both the revised ESRS and the voluntary standard are now in a two-month Parliamentary and Council scrutiny period (extendable by two further months) before entering into force. For sustainability counsel advising in-scope clients, the transition period option is material: firms that have invested in full-ESRS reporting infrastructure may elect to continue under the original standards rather than restructuring their reporting approach mid-cycle.
