Product-specific data
Account for materials, fabric formation, supplier processes, energy and geography.
Dynamic calculations
Refresh footprints as primary supplier data improves or product specifications change.
Recognised methods
Work with ISO, PEF and ADEME-aligned calculation and reporting requirements.
Trusted by fashion and retail teams
Build the footprint from the product that was actually made.
Connect the product specification to the material, fabric formation, manufacturing and supplier records behind it. Every input keeps its source, geography and evidence status.
- Product and material composition by weight
- Fabric formation and process-level supplier data
- Packaging, transport, use and end-of-life inputs

Use each facility’s location, process and energy mix to create primary LCA datasets. When a facility decarbonizes, its factor recalculates and the improvement flows into every connected product footprint.

Carbon Trail automatically fills missing product inputs, highlights every filled value for review and explains the reasoning behind it. Teams can replace any filled value when primary data becomes available.
- Allocate product weight intelligently across main and lining fabrics
- Review the reasoning and evidence behind every filled value
- Replace filled values and recalculate when primary data arrives

Product LCA questions for United States
Common questions from fashion and retail teams evaluating product LCA in United States.
Request a DemoWhat is life cycle assessment software?
Life Cycle Assessment (LCA) software is a tool that helps fashion retailers evaluate the environmental impact of a product like apparel or footwear over its entire life cycle, from farm to the end of life of the product.
What are the top 5 LCA software in the United States?
Beyond the manual LCA software like Simapro, GaBi, OpenLCA and Ecochain, Carbon Trail offers the most automated life cycle assessment modeling for fashion products like Apparel, Footwear, Bags, Home Textile, and Sports Equipment.
Which companies use life cycle assessment in the United States?
Many fashion brands like Nike and Coach rely on life cycle assessment in their effort to enhance the sustainability of their products. With the emergence ESPR legislation in the US, the use of LCA has become mainstream to model the impact of repair, reuse, and recycling of products.
What are the two main types of life cycle assessments?
The two main types of life cycle assessments used in fashion are "cradle-to-gate" and "cradle-to-grave", which differ in the scope of a product's life cycle they consider, with "cradle-to-gate" focusing only on the production stage (from raw material extraction to leaving the factory) while "cradle-to-grave" assesses the entire life cycle, including use and disposal stages.
Where is the life cycle assessment (LCA) used?
LCA serves as an important tool to identify emission hotspots while evaluating the environmental impacts of a product or industrial activity. Using primary data, companies can identify the true emission hotspots in the life cycle having significant negative impact on the environment.
