Europe’s top luxury houses are stepping up efforts to modernise how environmental data is collected across their supply chains, launching a unified approach designed to reduce reporting complexity and strengthen the fashion sector’s decarbonisation push. Through a new European Accelerator established by The Fashion Pact, brands such as CHANEL, Kering, Moncler Group and Prada Group are working together to bring consistency to supplier ESG reporting—an area where misalignment has long slowed progress.
The move targets a widespread challenge: suppliers often juggle multiple questionnaires and reporting formats depending on the brands they serve. This patchwork of requirements is especially burdensome for Europe’s many small and mid-sized manufacturers, who must dedicate time and resources to meeting overlapping demands. With more than 55 CEOs representing nearly a third of global fashion volume behind The Fashion Pact, the coalition is now using its collective weight to streamline these processes.
Eva von Alvensleben, Executive Director and Secretary General of The Fashion Pact, underscored the initiative’s significance. ‘Consistent data quality is essential for companies to understand emissions hotspots, craft credible decarbonisation plans and meet tightening European regulatory expectations’, she said.
Central to the Accelerator is a new harmonised questionnaire addressing energy use, water consumption and waste. Developed with support from Quantis and piloted with 74 suppliers across Italy, the questionnaire is designed to cut duplication and create more comparable datasets for brands. Early adopters are already integrating the framework, which will continue to evolve as new sustainability standards emerge.
For manufacturers, the impact is immediate. Lucia Mantero, Product Development Director at Mantero, said the pilot shifted focus away from navigating confusing templates and toward reporting accuracy: “The pilot allowed her company to focus on delivering accurate data rather than navigating brand-specific templates,” the statement reads.
The push for harmonisation arrives as suppliers confront mounting financial pressure. According to research from the TEHA Group, over half of European manufacturers lack access to the capital needed to invest in cleaner technologies—leaving a €4.4 billion funding gap if the industry is to meet its 2030 decarbonisation pathway. By establishing clear environmental baselines, the Accelerator hopes to help brands and suppliers identify where financing solutions or joint investment structures could accelerate progress.
Lorenzo Bertelli, Chief Marketing Officer and Head of Corporate Social Responsibility at Prada Group, noted that the shared framework offers ‘a more reliable basis for identifying the kinds of interventions that will matter most for Europe’s fragmented and highly specialised supply network.’
The initiative’s governance model—bringing together CEOs and sustainability leaders—aims to fast-track adoption across the sector. As Edoardo Zegna, Chief Marketing and Sustainability Officer at Ermenegildo Zegna Group, explained, transparency and sustained dialogue were central to building alignment.
With regulatory scrutiny intensifying, the European Accelerator may extend its influence far beyond the region. For investors, brands and policymakers, harmonised supplier data could become a cornerstone of evaluating transition readiness and demonstrating credibility on environmental action.
