Wooden Cutting Board

Material Composition Assumptions

A standard wooden cutting board weighs approximately 800 grams and consists primarily of solid hardwood such as oak, maple, walnut, or bamboo representing 95% of the total weight (760g). The remaining components include food-safe finishing treatments like mineral oil or water-based sealants accounting for 3% (24g), and cardboard packaging materials comprising 2% (16g). This composition reflects typical medium-sized cutting boards suitable for home kitchen use.

Manufacturing Geography

Primary manufacturing occurs in North America and Europe where sustainably managed forests provide ready access to hardwood species commonly used in cutting board production. These regions maintain established sawmill infrastructure with average grid intensities around 450 gCO2e/kWh for wood processing facilities. The concentration of manufacturing in temperate forest regions minimizes transportation distances from harvest sites to processing facilities while supporting local forestry economies.

Regional Variation

Manufacturing Region	Grid Intensity	Estimated CCI Score	Adjustment vs Default
North America	450 gCO2e/kWh	2.5	Baseline
Northern Europe	350 gCO2e/kWh	2.2	-12%
Southeast Asia	650 gCO2e/kWh	3.8	+52%
South America (tropical hardwoods)	550 gCO2e/kWh	5.2	+108%
Australia/New Zealand	400 gCO2e/kWh	2.3	-8%

Provenance Override Guidance

1. Forest certification documentation (FSC or PEFC) demonstrating sustainable harvesting practices and carbon sequestration rates
2. Transportation logs showing distance and mode of timber transport from forest to sawmill facility
3. Sawmill energy consumption data including kiln-drying duration, temperature profiles, and electricity source mix
4. Wood finishing process specifications detailing type and quantity of sealants or treatments applied
5. End-of-life management plans indicating biodegradation timelines or energy recovery efficiency rates

Methodology Notes

• The CCI score represents cradle-to-grave emissions for one standard cutting board including carbon sequestration benefits during tree growth
• Scope 1 and 2 emissions remain relatively low due to minimal processing requirements compared to synthetic alternatives
• Scope 3 dominates the footprint primarily through timber transportation and end-of-life considerations
• Functional unit assumes a 10-year product lifespan with proper maintenance and care
• Emissions exclude potential carbon credits from sustainable forest management practices
• Data gaps exist for small-scale artisan producers and exotic wood species with limited lifecycle documentation
