Picture Frame

Material Composition Assumptions

Picture frames consist of multiple components with varying material compositions depending on design and price point. The frame structure itself typically weighs between 200-400 grams and represents the largest portion of total mass. Wood frames dominate the market at approximately 60% share, utilizing solid hardwood, medium-density fiberboard, or finger-jointed poplar construction. Plastic and polystyrene frames account for roughly 25% of products, offering lightweight alternatives weighing 150-250 grams. Aluminum frames comprise about 10% of the market, providing durability with typical weights of 180-300 grams.

Glazing materials include either glass or acrylic sheets weighing 80-150 grams depending on thickness and frame dimensions. Supporting components such as cardboard backing materials, paper matting, and metal hardware contribute an additional 30-60 grams to total product weight. The complete assembled frame typically weighs between 300-600 grams with wood variants generally heavier than plastic alternatives.

Manufacturing Geography

Picture frame manufacturing concentrates primarily in China and Southeast Asian countries including Vietnam and Malaysia. These regions benefit from established supply chains for wood processing, plastic molding, and glass cutting operations. Manufacturing facilities in these areas typically rely on electricity grids with carbon intensities ranging from 500-650 grams of carbon dioxide per kilowatt-hour.

The concentration of frame production in Asia stems from access to raw materials, lower labor costs, and proximity to component suppliers. Wood frames often utilize imported lumber or locally sourced plantation timber, while plastic frames leverage established petrochemical processing infrastructure. Assembly operations remain labor-intensive, making regions with competitive wage structures attractive for manufacturers serving global markets.

European Union	280 gCO2/kWh	2.1	-16%
United States	400 gCO2/kWh	2.3	-8%
Southeast Asia	600 gCO2/kWh	2.7	+8%
India	650 gCO2/kWh	2.8	+12%

Provenance Override Guidance

1. Submit detailed material composition data specifying exact wood species, plastic resin types, metal alloy compositions, and glazing materials with corresponding weights for each component.

2. Provide manufacturing facility location with specific electricity grid data including renewable energy procurement agreements or on-site generation capabilities that differ from regional averages.

3. Document transportation logistics including shipping methods, distances from production to distribution centers, and packaging specifications with material weights and recyclable content percentages.

4. Supply energy consumption data from actual production processes including sawing, molding, joining, finishing, and assembly operations with fuel sources and efficiency metrics.

5. Furnish end-of-life management data demonstrating recycling programs, material recovery rates, or take-back initiatives that reduce disposal-related emissions below standard assumptions.

Methodology Notes

• The CCI score represents cradle-to-grave emissions for a single picture frame including all materials, manufacturing, transportation, and end-of-life disposal phases.

• Scope 3 emissions dominate at 87% of total impact due to raw material processing, long-distance shipping, and packaging requirements for small consumer goods.

• The functional unit assumes a standard rectangular frame suitable for an 8x10 inch photograph with typical glazing and backing materials.

• Biogenic carbon storage in wood frames partially offsets manufacturing emissions but is not credited in the CCI score due to uncertain permanence assumptions.

• Regional grid intensity significantly affects manufacturing emissions, particularly for energy-intensive processes like aluminum extrusion and glass melting.

• End-of-life recycling credits are limited due to mixed material construction that complicates separation and recovery processes.

• Transportation emissions vary significantly based on final market destination, with intercontinental shipping representing a substantial portion of total impact.
