ViewSonic LS901-4K Projector: Carbon Footprint Report
Report Produced: August 6, 2025
Introduction
ViewSonic is committed to corporate citizenship and environmental responsibility. This report details the comprehensive product life cycle carbon footprint for the ViewSonic LS901-4K Projector, aiming to empower customers to make informed purchasing decisions. The report quantifies greenhouse gas emissions across various lifecycle stages, utilizing emission factors from ecoinvent 3.11 and the MEE Announcement of 2022 Electricity Carbon Dioxide Emission Factor. This analysis adheres to recognized standards including the WRI's GHG Protocol for Product Life Cycle Accounting and Reporting Standard, PAS 2050, IEC TR 62921, ISO 14067, ISO 14040, and ISO 14044. The scope covers material sourcing and production (Cradle-to-Gate).

- Use stage: 43.94%
- End-of-life treatment: 1.55%
- Production: 0.54%
- Distribution: 0.10%
GHG Emission Contributed by Material
This section describes a pie chart detailing the greenhouse gas emissions breakdown by material type:
- Electronic: 92.921%
- Plastic: 4.768%
- Metal: 2.173%
- Others: 0.074%
- Packaging: 0.063%
Key Assumptions and Limitations
The following assumptions and limitations were considered in this report:
- Electricity emissions for the manufacturing phase were calculated using the grid emission factor of the production location (China), as per the MEE 2022 Announcement.
- Detailed product sales distribution data by region was not available at the time of this study. Therefore, carbon footprint results are presented as an unweighted average of four primary sales regions (Europe, United States, China, and Taiwan). Product delivery destinations are based on warehouses in these regions.
- According to Product Category Rules (PCR) for “Digital Projector” published by the Environmental Protection Administration of the Executive Yuan, Taiwan, total energy consumption during the use phase is calculated based on a scenario of 3.5 hours of use per day, 100 days per year, and a product lifetime of 5 years.
