ViewSonic LS740HD Projector: Carbon Footprint and Sustainability Report
Report Produced: August 6, 2025
Commitment to Environmental Responsibility
ViewSonic is committed to corporate citizenship and environmental responsibility. The company publishes comprehensive product life cycle carbon footprint reports to help customers make informed purchasing decisions. These reports quantify greenhouse gas emissions across each stage of a product's lifecycle, utilizing emission factor sources such as ecoinvent 3.11 and the MEE Announcement of 2022 Electricity Carbon Dioxide Emission Factor. This process adheres to standards including the WRI's GHG Protocol for Product Life Cycle Accounting and Reporting, PAS 2050, IEC TR 62921, ISO 14067, ISO 14040, and ISO 14044. The scope includes material sourcing and production (Cradle-to-Gate).

Impact by Lifecycle Stage and Manufacturing Components
GHG Emission Contributed by Material
A pie chart illustrates the greenhouse gas emissions contributed by different material types. The breakdown is as follows: Others (82.316%), Metal (11.772%), Plastic (5.583%), Electronic (0.180%), and Packaging (0.149%).
GHG Emission Proportion by Lifecycle Stage
A pie chart details the proportion of greenhouse gas emissions across various lifecycle stages. The distribution is: Use stage (64.80%), Raw material (32.32%), Production (1.14%), Distribution (0.14%), and End-of-life treatment (1.60%).
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.
- Detailed product sales distribution data by region was not available at the time of this study. Therefore, the product 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, over a product lifetime of 5 years.
ViewSonic's Environmental Commitment
ViewSonic prioritizes sustainability across its operations and product lifecycles, from development and production to customer use and disposal. The company adheres to responsible practices and ensures compliance with ISO 14000 Environmental Management Standards throughout its global supply chain. To reduce waste and promote a sustainable future, ViewSonic incorporates recycled materials into its product lines and eco-friendly packaging. These efforts aim to contribute positively to the environment.
