Since 2022, the Business Weekly Carbon Competitiveness Survey has collaborated with industry and academic experts to launch Taiwan's first corporate ranking focused on "carbon." Radiant Opto-Electronics has been selected for three consecutive years. According to the survey, 2024 marks the third year of the initiative, with 477 publicly listed companies qualifying, and only 32 companies have made the list for three consecutive years, while 50 companies have been selected for two years.

Radiant Opto-Electronics upholds a sustainability vision centered on "Environmental Coexistence," "Social Prosperity," and "Mutual Benefit." Under its Sustainability Development Committee, the company has established dedicated teams for "Low-Carbon Products," "Energy Efficiency," and "Green Procurement & Logistics" to address carbon management. Through initiatives spanning product design, manufacturing, and supply chain management, Raydium aims to drive carbon reduction efforts and work together toward achieving its net-zero vision.
