ViewSonic LS741HD Projector
Report Produced: August 6, 2025
Committed to corporate citizenship and environmental responsibility, ViewSonic publishes comprehensive product life cycle carbon footprint reports to empower customers to make informed purchasing decisions. These reports transparently quantify greenhouse gas emissions associated with each stage of a product's lifecycle by utilizing the emission factor source ecoinvent 3.11 and 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).

Impact by Lifecycle Stage and Manufacturing Components
A pie chart illustrating Greenhouse Gas (GHG) emissions contributed by material composition. The largest segment, representing 83.129%, is labeled 'Electronic'. 'Packaging' accounts for 11.042%. 'Plastic' makes up 5.532%. 'Metal' contributes 0.155%, and 'Others' represent 0.142%.
A pie chart showing the proportion of Greenhouse Gas (GHG) emissions across different lifecycle stages. The 'Use stage' is the largest contributor at 61.91%. 'Raw material' accounts for 35.15%. 'End-of-life treatment' is 1.63%. 'Production' contributes 1.16%, and 'Distribution' is 0.15%.
Key Assumptions and Limitations
I. Electricity emissions for the manufacturing phase were calculated using the grid emission factor of the production location (China), as per the MEE 2022 Announcement.
II. 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.
III. 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.
