Pet Carrier (plastic)

Material Composition Assumptions

The typical plastic pet carrier consists primarily of polyethylene terephthalate (PET) as the main structural material. Virgin PET resin, derived from petroleum-based feedstocks including crude oil and natural gas, comprises approximately 85% of the total weight at roughly 1,275 grams. The injection-molded plastic components form the carrier body, door, and ventilation grilles using standard manufacturing processes. Some products incorporate recycled PET content, which can significantly reduce the overall carbon footprint when virgin material is displaced. Minor components include synthetic fabrics for door seals and minimal adhesive materials, totaling approximately 15% of the product weight at 225 grams.

Manufacturing Geography

The majority of plastic pet carriers are manufactured in China, which dominates global PET production and plastic goods manufacturing. Chinese manufacturing facilities operate on a national electrical grid with relatively high carbon intensity at 547 grams of carbon dioxide equivalent per kilowatt-hour. This region maintains cost advantages for large-scale injection molding operations and benefits from established supply chains for PET resin production. The concentration of manufacturing in China reflects both economic factors and the proximity to major petrochemical production facilities that supply virgin PET feedstock materials.

Regional Variation

Manufacturing Region	Grid Intensity	Estimated CCI Score	Adjustment vs Default
China	547 gCO2/kWh	48	Baseline
European Union	255 gCO2/kWh	42	-12.5%

South Korea	436 gCO2/kWh	46	-4.2%

Provenance Override Guidance

1. Submit detailed material composition data showing the percentage of recycled PET content versus virgin PET resin, including supplier certifications for recycled content claims.

2. Provide manufacturing facility energy consumption records and local grid carbon intensity data, along with any renewable energy purchasing agreements or on-site generation.

3. Document transportation modes and distances from PET resin suppliers to manufacturing facilities, and from production sites to distribution centers or end customers.

4. Supply injection molding process specifications including cycle times, energy consumption per unit, and waste material recovery rates during production.

5. Present end-of-life management data for the specific market region, including local recycling rates, waste-to-energy recovery, and landfill disposal percentages.

Methodology Notes

• The CCI score represents cradle-to-grave emissions for a standard medium-sized plastic pet carrier weighing approximately 1.5 kilograms total.

• Scope 3 emissions dominate the carbon footprint due to upstream PET resin production from fossil fuel feedstocks and energy-intensive polymerization processes.

• The functional unit assumes a durable product with multiple uses over several years of pet transportation needs.

• Manufacturing energy for injection molding processes contributes significantly to Scope 2 emissions based on local electricity grid intensity.

• The assessment excludes optional accessories like food bowls, bedding materials, or aftermarket modifications that consumers may add separately.

• Data gaps exist around regional variations in PET recycling infrastructure and the actual recycled content in mass-market pet carriers.
