ViewSonic LS901HD Projector
Report Produced: August 6, 2025
Commitment to Corporate Citizenship and Environmental Responsibility
ViewSonic is committed to corporate citizenship and environmental responsibility. The company publishes comprehensive product life cycle carbon footprint reports to empower customers to make informed purchasing decisions. These reports transparently quantify the greenhouse gas emissions associated with each stage of a product's lifecycle. They utilize the emission factor source ecoinvent 3.11 and the MEE Announcement of 2022 Electricity Carbon Dioxide Emission Factor. This is done in compliance with the WRI's GHG Protocol for Product Life Cycle Accounting and Reporting Standard, PAS 2050, IEC TR 62921, as well as ISO 14067, ISO 14040, and ISO 14044. The stages covered include material sourcing and production (Cradle-to-Gate).

Lifecycle Stage and Manufacturing Components Analysis
The document includes analyses of greenhouse gas emissions by material and by lifecycle stage, presented visually in pie charts.
GHG Emission Contributed by Material
The pie chart titled 'GHG Emission Contributed by Material' shows that electronic components contribute the vast majority (92.698%) of emissions. Plastic accounts for 4.917%, metal for 2.243%, packaging for 0.065%, and other materials for 0.076%.
GHG Emission Proportion by Lifecycle Stage
The pie chart titled 'GHG Emission Proportion' illustrates emissions across the product lifecycle. Raw material acquisition accounts for the largest share (56.82%), followed by production (40.80%). Distribution contributes 0.59%, the use stage 1.68%, and end-of-life treatment 0.11%.
Key Assumptions and Limitations
- Electricity emissions for the manufacturing phase were calculated using the grid emission factor of the production location (China), as per the MEE 2022 Announcement.
- At the time of this study, detailed product sales distribution data by region was not available. Therefore, the product carbon footprint results are currently presented as an unweighted average of the four primary sales regions (Europe, United States, China, and Taiwan). The product delivery destinations are based on the warehouses located in these four major sales regions.
- According to Product Category Rules (PCR) for “Digital Projector" published by the Environmental Protection Administration of the Executive Yuan, Taiwan, the total energy consumption during the use phase is calculated based on the following usage scenario: 3.5 hours of use per day, 100 days per year, and a product lifetime of 5 years.
