Soy wax candles represent a plant-based alternative to petroleum-derived paraffin candles, manufactured from hydrogenated soybean oil through industrial processing. While marketed as environmentally preferable, these products carry significant embedded emissions from agricultural production, chemical processing, and global supply chain activities.

Material Composition Assumptions

A typical soy wax candle weighing approximately 250 grams contains the following components:

The hydrogenated soybean oil undergoes chemical modification to achieve appropriate melting point and burning properties for candle applications.

Manufacturing Geography

Primary production occurs in the United States and Brazil, representing the world’s largest soybean cultivation regions. The United States dominates soy wax processing with an electrical grid intensity of 0.42 kg CO₂e per kilowatt-hour, driven by mixed fossil fuel and renewable generation sources.

American manufacturing facilities benefit from established agricultural supply chains and proximity to major soybean growing states. Brazilian production carries higher transportation emissions when serving global markets, while benefiting from lower labor costs and expanding agricultural capacity.

Provenance Override Guidance

Suppliers can submit the following data types to override the default CCI score:

  1. Certified sustainable soybean sourcing documentation with deforestation-free supply chain verification
  2. Processing facility energy consumption records with renewable electricity procurement contracts
  3. Transportation distance measurements from soybean farms through wax processing to final manufacturing
  4. Agricultural input intensity data including fertilizer application rates and pesticide usage per hectare
  5. Hydrogenation process efficiency metrics with energy consumption per kilogram of finished wax produced
