Carbonfact Acquires Vaayu, Uniting Fashion's Two Largest Environmental Sustainability Platforms

Written by Marc Laurent | May 28, 2026 6:55:00 AM

Today, we're announcing that Vaayu is joining Carbonfact.

Carbonfact and Vaayu spent the last few years building from the same conviction: that decarbonization in fashion is a data problem, and that the industry needs a purpose-built platform rather than retrofitted generic tools.

Vaayu, founded in Berlin in 2020 by Namrata Sandhu, built one of fashion's first product impact platforms, working with 100+ brands including New Balance, Axel Arigato, Ace & Tate, and Asket. Carbonfact, founded in Paris in 2021, built the environmental data platform now used by 200+ apparel and footwear brands, including On, Ganni, The North Face, Burton, and Marc O'Polo.

Bringing these two platforms together gives the industry what it has been missing: a single, comprehensive, product-level environmental dataset.

“We started Vaayu to give retail and fashion companies the granular, product-level climate data they need to actually decarbonize, not just report on it. Carbonfact shares that conviction, and together we can deliver it at the scale this industry now requires. Our customers will get the same rigor they trust us for, now paired with the compliance coverage their next chapter demands.” - Namrata Sandhu, Founder and CEO, Vaayu

One dataset for the new wave of regulation

The next two years will reshape how fashion brands measure and report environmental impact. The Digital Product Passport (DPP), the Ecodesign for Sustainable Products Regulation (ESPR), the French Eco-Score, CSRD, California's SB 253, and the Empowering Consumers Directive (EmpCo) all share one requirement: defensible environmental data at the product level.

This is a shift from corporate-level reporting to product-level reporting. Spend-based estimates are no longer enough. The industry needs a deeper, more granular dataset, built on primary data from the supply chain.

With Vaayu's expertise joining, the Carbonfact platform now brings together:

  • 150,000+ fashion-specific emission factors, covering the materials, processes, and finishes that actually appear in apparel and footwear bills of materials.

  • 200+ textile-specific processes covered and 650+ material categories across 144 countries, the granularity needed for product-level reporting.

  • 50+ patented materials and processes, with 7,500+ bespoke emission factors created for brands.

  • Energy data from 7,000+ textile factories, collected through Carbonfact for Suppliers.

  • 2 million product textile and footwear LCAs performed on a daily basis for our customers

  • A combined customer base of 300+ apparel and footwear brands, the largest network of fashion brands working on a single environmental data foundation.

From measurement to reduction, on one platform, methodology, and dataset

Carbonfact's platform covers the full environmental workflow in one place, on one dataset:

  • Carbon accounting: GHG Protocol compliant, audit-ready, and PwC-reviewed.

  • Product impact measurement: PEFCR-aligned LCAs at the SKU level.

  • Decarbonization: Eco-Design, hotspot analysis, and decarbonization planning aligned to SBTi targets.

  • Environmental reporting: including the Digital Product Passport, French Eco-Score, CSRD, and SBTi.

These have historically been separate tools, based on separate methodologies and datasets. We built Carbonfact on a single dataset and a single methodology, so brands can measure once and report everywhere.

What comes next: from data to intelligence

As the amount of product-level data grows, the biggest challenge will no longer be collecting it. It's making sense of it. Carbonfact is building toward what we call Environmental Intelligence: an AI-powered layer that makes complex climate expertise accessible and actionable for every team in a fashion organization, enabling every brand to move beyond compliance reporting and actually reduce its impact.

Decarbonizing fashion is the shared mission that led to the creation of Carbonfact and Vaayu, and why bringing the two platforms together matters. The more brands working on a shared foundation, the faster the industry can move from measuring its impact to reducing it. Over the coming months, we'll work closely with the Vaayu team on the transition and help their customers get set up on Carbonfact.

For now: thank you to the Vaayu team for the work they've done to help build this category, to Namrata for her partnership in making this happen, and to the 300+ brands who continue to trust us with one of the hardest data problems in the industry.

We have a lot of work ahead.
