Manufacturing Geography
- Region

Material Composition Assumptions
The default reference product is 1 kg of liquid laundry detergent, composed of:
- Surfactants: Linear alkylbenzene sulfonate (LAS) and/or alcohol ethoxylates, approximately 15-25% by weight. Derived from petrochemical (LAB from kerosene) or oleochemical (palm kernel/coconut oil) feedstocks.
- Builders: Sodium carbonate (soda ash), zeolites, or citric acid to soften water and enhance cleaning. Approximately 5-15%.
- Enzymes: Protease, amylase, lipase, and/or cellulase. <1% by weight but significant cleaning contribution.
- Water: 50-70% of liquid detergent formulations.
- Other: Fragrances, optical brighteners, dye transfer inhibitors, preservatives. <5% combined.
- Packaging: HDPE bottle (~40-60 g per kg of product) or flexible pouch (~15-25 g per kg).
Liquid detergents have lower production emissions per dose than powders (no spray-drying energy) but higher water content increases transport emissions. Concentrated formulas reduce both effects.
Manufacturing Geography
Laundry detergent manufacturing is dominated by multinational FMCG companies:
- USA: P&G (Tide), Henkel (Persil/all), Church & Dwight (OxiClean).
- EU: P&G, Henkel (Düsseldorf), Unilever, Reckitt.
- China: Domestic brands (Liby, Blue Moon) plus MNC factories.
- India: Hindustan Unilever, P&G India, Nirma.
Regional Variation
| Manufacturing Region | Estimated Score (per kg) | Adjustment |
|---|---|---|
| Global average (default) | 1.0 kgCO2e | Baseline |
| EU | 0.8 kgCO2e | -20% (lower-carbon grid, concentrated formats) |
| USA | 1.0 kgCO2e | Baseline |
| China | 1.2 kgCO2e | +20% |
| India | 1.2 kgCO2e | +20% |
Provenance Override Guidance
- Product-level PCF per ISO 14067 or EU PEF methodology for detergents.
- Formulation data: Concentrated products (2x-4x) reduce per-dose emissions. Cold-water-effective formulas (enzymes, surfactant optimization) reduce use-phase emissions.
- Surfactant sourcing: RSPO-certified palm kernel oil derivatives for oleochemical surfactants.
- Packaging: PCR HDPE content, lightweight/flexible pouches, or refill systems.
Methodology Notes
- CCI score of 1 kgCO2e/kg is consistent with Saouter et al. (2017) EU PEF pilot data reporting 0.5-1.5 kgCO2e/kg for laundry detergents.
- Scope breakdown: Scope 3 at 80% (0.8 kgCO2e/kg) from surfactant production, filler chemicals, and packaging. Scope 1 at 10% (0.1 kgCO2e/kg). Scope 2 at 10% (0.1 kgCO2e/kg).
- Confidence: Medium — the EU PEF pilot for detergents provides relatively good sector-level data, and major brands (P&G, Unilever) disclose lifecycle data.
- Functional unit: 1 kg of liquid laundry detergent, cradle to gate.
- Use-phase dominance: Production emissions (~1 kgCO2e/kg) are a small fraction of lifecycle emissions. Koehler & Wildbolz (2009) and P&G data show that heating water for warm/hot wash cycles dominates the lifecycle by 5-10x. This makes cold-water washing the single most effective emissions reduction lever.
