Exclusive Invite-Only Workshop
Decarbonizing Leather:
Closing Data Gaps with Brands and Suppliers
Join us for an exclusive workshop dedicated to accelerating decarbonization in leather production and sourcing — designed specifically for sustainability leaders in apparel and footwear. This event is invite only, and free.
Confirmed participants from leading brands, including:
Closing Environmental Data Gaps in Leather
With participants from leading fashion houses, this session brings together material innovators, data scientists, and sustainability strategists to confront one of the industry’s biggest challenges: closing the data gaps in leather supply chains.
Don’t miss the opportunity to be part of the conversation shaping the future of low-impact leather.

Traceability Gaps Measuring Leather Emissions
Accurate emission data for conventional leather is lacking. Existing datasets are often paywalled, incomplete, or too aggregated to identify hotspots and prioritize action. While chrome-tanned leather can be modeled with literature data, other tanning technologies remain poorly represented.
The goal of the session is to co-design a path toward open, primary-data-based leather datasets that the entire industry can access, understand which emission factors (EFs) are currently in use and where the key data gaps are.
Decarbonizing Leather
We need to identify clear levers to reduce emissions from conventional leather across its life cycle. At the same time, many brands are exploring alternative materials — but navigating options, ensuring LCA consistency, and comparing impacts across suppliers remains difficult for any single brand.
Goal of the session is to map actionable decarbonization strategies for real leather and align on priority leather alternatives to assess consistently across the industry.

What you'll get
- A unique chance to connect with fellow sustainability leaders from top brands facing similar challenges — and collaborate on practical solutions.
- Clarity on where the data gaps are in leather emission factors — and how to start filling them.
- Actionable insights from experts and innovators on decarbonization strategies, material choices, and measuring true impact
