Delta has long history of being a leader in the
environmental, social, and governance (ESG) space. Among companies based in Taiwan, it was the first to issue a Corporate Social Responsibility (ESG) report in 2005, and publishes a new report annually. It has been listed on the
Dow Jones Sustainability Indices for 14 consecutive years and has achieved a top 10%
S&P Global CSA score in its most recent 2024 ranking. Delta was named 24th in
Time Magazine's 2024 ranking of the world's most
sustainable companies. In addition, Delta was awarded double A-list ratings for the third time in a row by the
CDP (formerly Carbon Disclosure Project) in their most recent 2024 ratings. The company has engaged in a joint project with the
National Museum of Marine Science and Technology to engage in
coral reef restoration off the northeast coast of
Taiwan. Through an ambitious
diving program helmed by forty volunteer divers who are also Delta employees, the company plans to transplant and breed over a thousand corals to the
marine protected areas around Taiwan. The coral breeding project adopts
cryopreservation techniques and Delta's own
LED lamps for restoration of the delicate ecosystem. Delta's U.S. headquarters in
Fremont, California, was built in 2016. It showcases many of Delta's own
green energy and
building automation products in its build. Prominently, it features a
geothermal heat pump system and a full
rooftop solar system. Delta's own products are most visible through the
photovoltaic power generating systems on the roof and carports, the
electric vehicle charging stations throughout the property, and managed
LED lighting systems. The building was awarded a
LEED Zero Energy certification in 2022, an upgrade from the LEED Platinum designation it achieved at the time it was built. At the time of completion, it was the first green
building with net-zero energy consumption in the city of Fremont and only the second in the
San Francisco Bay Area. ==History==
