How Mammut turned product footprints into a comparable climate baseline.
Mammut needed LCAs that could represent complex outdoor products—from apparel and footwear to component-heavy hardgoods—and turn product data into credible reduction scenarios. The same evidence supported a transparent corporate rebaseline.

“Working with Carbon Trail has deepened our understanding of product impacts, enabling us to move beyond basic reporting and use these insights to inform strategic decision-making.”
Complex outdoor products needed more than a generic LCA.
Mammut needed LCAs that understood how technical outdoor products are actually built, then used that product evidence to identify credible ways to reduce their impact.
A rope, carabiner, crash pad or technical garment can combine very different materials, components and processes. Some products had detailed bills of materials while others had only partial primary data. The same evidence also had to support Mammut’s corporate rebaseline.
One evidence trail, adapted to the data available.
Carbon Trail combined category-specific product models, factory energy and water data, and corporate activity records. Assumptions and data gaps remained visible for review.
- CollectBring disparate inputs together
BOMs, product records, PCFs and facility data were ingested with approaches suited to each category and its data quality.
- CalculateRepresent complex outdoor products
Hardgoods used component and process-level detail where available and transparent gap-filling where data was incomplete.
- RebaselineConnect PCFs to GHG accounting
The product evidence supported restatement of 2018 and 2024 alongside 2025 accounting, with a rationale for leadership and public reporting.
- ModelTurn LCAs into reduction plans
Teams evaluated circular business models, packaging changes, lower-impact materials and lower energy use across Tier 1 and Tier 2 factories.
Product LCAs became a decision tool.
Mammut gained a more detailed view of complex outdoor-product impacts and a consistent evidence base for reporting and reduction planning. Modelled scenarios are possibilities, not claimed reductions.
| Measure | Before Carbon Trail | With Carbon Trail | Change |
|---|---|---|---|
| Product coverage | Category data in different formats and levels of detail | 3.2k+ SKUs assessed | Category-specific LCAs across four product families |
| Corporate accounting | Historical figures on a prior methodology | 17.6k activities across 2018, 2024 and 2025 | Restated periods for a more comparable baseline |
| Supplier evidence | Facility data separate from product decisions | Primary data from ~60 factories, supported by 247 Tier 1 and Tier 2 process datasets | More supplier-specific inputs for LCAs |
| Decarbonization planning | Product and supply-chain ideas difficult to quantify together | Product and factory scenarios evaluated against the same evidence base | Levers compared in one practical plan |
Different products. One accountable method.
A rope, a jacket and a boot do not arrive with the same evidence. Mammut's workflow matched the calculation method to each category without treating missing primary data as a reason to stop.
Detailed bills of materials
Primary BOMs were complemented by Mammut-specific, PEF and industry assumptions where fields were missing.
Reusable product structures
Representative constructions could be duplicated and adjusted across related styles instead of rebuilt from scratch.
Granular when possible
Component and process inputs refined equipment LCAs even when only part of a product had primary data.
Primary product BOMs
Available material and component records were used to establish category-specific footprints.
From rebaseline to roadmap.
The PCF work did more than refresh a product dashboard. It helped explain the revised 2018 and 2024 figures to the Chief Supply Chain Officer and CEO, then supported communication of the methodology change in Mammut's 2025 Responsibility Report.
Circularity belongs in the model.
Mammut can compare circular business models with other product and supply-chain levers, see where reductions could come from and decide which options merit deeper validation. These are modelled pathways, not realised carbon savings.
