Throughout the year, Delta continuously achieves significant milestones in its business and in its pursuit for sustainable development. This section intends to condense and review some of Delta’s most valuable milestones and initiatives recently. These are:

In March 2021, Delta announced it has joined RE100, a global initiative bringing together the world’s most influential businesses that entails the commitment of 100% renewable energy use and carbon neutrality in their global operations. With the aforementioned pledge, Delta becomes the first high-tech company in Taiwan to target the RE100 goal by 2030. Delta implemented Science Based Targets (SBTs) in 2017, committing to a reduction in carbon intensity by 56.6% by 2025. In 2020, its carbon intensity dropped by more than 32% and renewable energy usage rate is expected to cover about 45% of its total electricity consumption. Delta’s board of directors and ESG committee have also set an internal carbon price of US$300 per metric ton in 2021 for its global operations to further encourage lower carbon emissions. That carbon fee will fund internal energy conservation projects and the procurement of renewable energy. These initiatives underscore Delta’s continuous contributions towards carbon neutrality, a pillar of sustainable development.

In 2022, Delta was once again selected for a double A List rating on the two environmental issues of "climate change" and "water security management" in the 2022 CDP evaluation. Delta was one of 57 companies selected for the double A List on these two issues among 18,700 companies in the world evaluated by CDP this year. Delta has been selected for the A List for three consecutive years on the "water security" issue, making Delta a leader in Taiwan's industry recognized for its specific actions in responding to climate change and water security risks.
