Drip Coffee Maker

Material Composition Assumptions

A typical drip coffee maker weighs approximately 1.2 kg and consists of multiple material components. The plastic housing and internal components comprise the largest portion at roughly 600 grams, representing 50% of total weight. The stainless steel or glass carafe accounts for approximately 400 grams or 33% of the unit mass. The internal heating element, constructed from resistive wire or metal coils, contributes about 120 grams representing 10% of weight. Paper filters used during operation add minimal weight per unit but represent ongoing consumable inputs. Minor electrical connections, gaskets, and control components make up the remaining 80 grams or 7% of total product weight.

Manufacturing Geography

Drip coffee makers are primarily manufactured in China, which produces over 70% of global small kitchen appliances. Chinese manufacturing facilities benefit from established supply chains for plastic injection molding, metal fabrication, and electrical component assembly. The country’s grid intensity of 555 gCO2e per kilowatt-hour significantly influences the Scope 2 emissions profile during production. Manufacturing clusters in Guangdong and Zhejiang provinces provide access to specialized suppliers for heating elements, electronic controls, and packaging materials while maintaining cost competitiveness for global export markets.

Regional Variation

Manufacturing Region	Grid Intensity	Estimated CCI Score	Adjustment vs Default
China	555 gCO2e/kWh	58	Baseline
Germany	366 gCO2e/kWh	51	-12%
Mexico	418 gCO2e/kWh	54	-7%
Turkey	435 gCO2e/kWh	55	-5%
India	708 gCO2e/kWh	65	+12%

Provenance Override Guidance

1. Submit manufacturing facility energy consumption data showing actual electricity usage per unit produced, including both direct production and facility overhead allocation.

2. Provide material composition specifications with exact weights and percentages for plastic resins, metals, and electronic components sourced from verified suppliers.

3. Document regional electricity grid mix and renewable energy procurement certificates if manufacturing facility uses clean energy contracts.

4. Supply transportation logistics data showing shipping distances and modal splits from component suppliers to assembly facilities and final distribution points.

5. Submit end-of-life treatment data for product components including recycling rates for metals and plastics in target markets.

Methodology Notes

• The CCI score represents cradle-to-gate emissions for the drip coffee maker unit itself, excluding coffee beans, filters, and operational energy consumption during use phase.

• Scope 2 emissions reflect manufacturing energy intensity while Scope 3 dominates due to upstream material production and supply chain complexity.

• Functional unit is defined as one complete drip coffee maker capable of brewing standard batch sizes with expected 5-7 year service life.

• Exclusions include packaging materials, retail distribution beyond manufacturing gate, and consumer disposal scenarios which vary significantly by region.

• Data gaps exist for specific supplier energy profiles and transportation distances, requiring industry average assumptions for material sourcing footprints.
