Material Composition Assumptions
The default reference product is a flat-pack bookcase or shelving unit weighing approximately 20 kg, composed of:
- Particleboard or MDF panels: 70-80% of total mass (~14-16 kg). Made from wood chips/fibers bonded with urea-formaldehyde (UF) or melamine-urea-formaldehyde (MUF) resin at 8-12% resin content by weight.
- Melamine or paper foil laminate: Surface coating applied to visible faces, approximately 0.5-1.0 kg per unit.
- Edge banding: PVC or ABS plastic edge tape, approximately 50-100 g per unit.
- Hardware: Steel cam locks, dowels, shelf pins, screws, and back-panel nails — approximately 0.3-0.5 kg of zinc-plated steel.
- Back panel: 3 mm HDF (high-density fiberboard) or hardboard — approximately 1-2 kg.
- Packaging: Corrugated cardboard box, EPS corner protectors, polyethylene wrap, assembly instructions — approximately 1.5-2.5 kg.
Flat-pack furniture uses composite wood panels rather than solid timber. The resin binder (UF or MUF) is derived from petrochemical feedstocks and contributes significantly to both embodied carbon and formaldehyde emissions during production and use.
Manufacturing Geography
The default manufacturing region reflects the global flat-pack furniture supply chain:
- Panel production: Major particleboard/MDF producers include China (world’s largest), Poland, Germany, and Turkey. Panel mills are typically co-located with forestry resources.
- Furniture manufacturing and assembly: China (dominant global exporter), Poland (largest EU furniture exporter), Sweden (IKEA supply chain), and Vietnam (growing share).
- Grid intensity (China): 565 gCO2e/kWh (IEA 2024). Used as the conservative default.
- Grid intensity (Poland): 640 gCO2e/kWh (IEA 2024). Poland has one of the most coal-intensive grids in the EU.
- Grid intensity (Sweden): ~13 gCO2e/kWh (IEA 2024). Near-zero grid due to hydro and nuclear.
- Rationale: Particleboard and MDF production is thermally intensive — hot pressing at 180-220 degC requires significant steam or thermal oil energy. Many panel mills use wood waste (bark, sawdust) as biomass fuel for process heat, which can substantially reduce fossil-fuel-derived Scope 1 emissions.
Regional Variation
| Manufacturing Region | Grid Intensity | Estimated CCI Score | Adjustment vs Default |
|---|---|---|---|
| China (default) | ~565 gCO2e/kWh | 40.0 kgCO2e | Baseline |
| Poland | ~640 gCO2e/kWh | 41.5 kgCO2e | +4% |
| Germany | ~350 gCO2e/kWh | 36.7 kgCO2e | -8% |
| Sweden | ~13 gCO2e/kWh | 31.7 kgCO2e | -21% |
| Vietnam | ~480 gCO2e/kWh | 38.6 kgCO2e | -4% |
Note: Scope 2 represents 20% of total emissions. Swedish production benefits from an extremely low-carbon grid, but upstream resin production and transport emissions (Scope 3) remain significant regardless of manufacturing location.
Provenance Override Guidance
A supplier or brand may override the default CCI score by submitting:
- Environmental Product Declaration (EPD) per EN 15804 or ISO 14025 covering the finished furniture product.
- Panel supplier EPD or PCF for particleboard/MDF used, specifying resin type, wood source (FSC/PEFC certified), and production energy mix.
- Factory energy data including biomass fuel fraction, renewable electricity procurement, and fossil fuel consumption for pressing and drying.
- Transport data: Flat-pack furniture is significantly more transport-efficient than assembled furniture (typically 3-5x higher packing density). Specific logistics data (sea freight vs. rail vs. truck, distance to market) can refine the transport component.
- Recycled content data: Use of post-consumer recycled wood chips in particleboard can reduce upstream forestry emissions.
Methodology Notes
- CCI score of 40 kgCO2e represents a conservative estimate for a medium-sized flat-pack bookcase (~20 kg). Based on composite wood panel EPD data (0.5-1.0 kgCO2e/kg for panels) scaled to a complete furniture unit including hardware, packaging, and assembly energy.
- Scope breakdown: Scope 3 dominates at 73% (29.0 kgCO2e), driven by resin production, upstream panel manufacturing at supplier facilities, steel hardware production, and transport logistics. Scope 2 is 20% (8.0 kgCO2e) from factory electricity for CNC cutting, edge banding, and surface lamination. Scope 1 is 7% (3.0 kgCO2e) from on-site thermal energy for pressing and drying.
- Functional unit: One flat-pack bookcase unit (~20 kg), cradle to gate through packaged product ready for distribution.
- Biogenic carbon: Wood-based panels contain sequestered biogenic carbon (~50% of dry wood mass is carbon). Following EN 15804 and PAS 2050 convention, biogenic carbon storage is reported separately and excluded from the CCI score pending standardized accounting rules.
- Data gaps: Significant variation exists between product types (small shelf vs. large wardrobe). The 20 kg bookcase is used as a representative mid-range unit. Larger items like wardrobes (40-60 kg) would scale approximately proportionally by mass.
