Kemchain enables Sustainability & Procurement teams to measure, predict, and reduce upstream carbon emissions at ingredient, supplier, and formula level. This helps companies move from generic Scope 3 estimates to traceable, science-based carbon data that supports better supplier decisions and more credible ESG reporting.

Business challenge

Scope 3 Category 1 emissions from purchased goods and services often represent the largest and least visible part of the carbon footprint in the chemical, cosmetic, and fragrance sectors. Many teams either do not report them properly or rely on generic emission factors that are disconnected from real supplier processes and transport routes, making it hard to drive reduction decisions or support credible CSRD and ESPR disclosures.

Solution

Kemchain uses process-based estimation and transport impact calculation to generate traceable carbon values for raw materials, suppliers, and formulas. The platform matches substances with records in the Ecoinvent v3.11 Cut-off database, calculates logistics emissions by transport mode and distance, enables side-by-side supplier carbon benchmarking, and aggregates ingredient-level emissions into formula-level carbon footprints.

Key capabilities

Process-based emission estimation
Estimates production inventories for each substance through process similarity matching with Ecoinvent v3.11 Cut-off records.

Transport impact calculation
Calculates logistics emissions using actual transport distances and emission factors for road, sea, rail, and air.

Supplier carbon benchmarking
Enables side-by-side carbon comparison of equivalent ingredients from different suppliers and origins.

Formula-level carbon values
Aggregates ingredient-level emissions into product formulas so teams can calculate product footprints and model reformulation scenarios.

Methodology grounded in Ecoinvent
Uses the Ecoinvent v3.11 Cut-off database as the science-based reference for Life Cycle Inventory data.

Results

Credible Scope 3 reporting with auditable, science-based emission factors.
Supplier selection based on carbon impact, not only price.
A targeted reduction roadmap focused on the raw materials and logistics stages with the biggest footprint.
Carbon embedded into product development from the first prototype stage.

Industry best fit

Chemical, cosmetic, and fragrance companies that need better upstream carbon visibility across raw materials, suppliers, logistics, and formulations.
