Achieving milestone results in the RE and EV phases 
Under the RE100 initiative, Delta is committed to sourcing 100% renewable electricity for its global operation sites by 2030. To this end, Delta actively develops on-site solar generation for self-consumption, signs power purchase agreements (PPAs) for renewable electricity, purchases green electricity products, and acquires unbundled energy attribute certificates (EACs). By 2024, renewable electricity accounted for 84% of Delta's global operations, surpassing its internal RE74 interim target.

Within the EV100 initiative, as of the end of 2024, electric vehicles made up 36% of Delta's corporate fleet (or 25% excluding plug-in hybrid vehicles), totaling 110 units. In addition, 233 charging stations had been installed across sites to encourage employees and customers to use EVs. In the future, Delta plans to provide charging facilities at all global operational and manufacturing sites within its energy management scope by 2030 and to fully transition its corporate fleet to electric vehicles, replacing plug-in hybrids.

Robust governance and charging technology to overcome implementation challenges
Delta's efforts to promote renewable electricity and vehicle electrification have faced numerous challenges along the way. Regarding RE100, Delta operates over 190 sites worldwide, many of which are small-scale facilities, making it difficult to achieve the economies of scale required for power purchase agreements (PPAs) for renewable electricity. Additionally, the maturity of renewable energy policies varies across countries, and market transparency is often insufficient, adding complexity to the procurement of renewable electricity.

To address these challenges, Delta established a global RE100 Committee, organized eight regional working groups, and, starting in 2022, incorporated renewable electricity achievement rates into the performance metrics of the Chairman, CEO, and regional heads of each working group, affecting 5–15% of their performance-based compensation. Each working group has dedicated personnel who frequently negotiate with local renewable electricity providers to ensure that renewable electricity across different countries meets RE100 standards. In countries where signing PPAs or purchasing green power products is difficult, Delta uses unbundled energy attribute certificates (EACs) to facilitate achievement.

During the EV100 implementation, Delta encountered rapid growth in employee EV ownership. For example, at the Shanghai R&D building, by the end of 2024, the number of employee-owned electric vehicles exceeded 170, accounting for 36% of staff vehicles. This trend not only caused congestion at charging stations but also significantly increased electricity demand, putting pressure on grid stability.

To address large-scale charging demands, Delta established an internal "Charging Management Policy" to ensure fair and efficient use of charging stations. Additionally, Delta deployed integrated “solar-storage-charging” systems at manufacturing sites, combining solar generation, energy storage, and EV charging to maximize the use of renewable electricity. The system, supported by the DeltaGrid® EVM electric vehicle charging management platform, optimizes energy supply and demand. Through this smart charging solution, the Shanghai R&D building successfully increased off-peak electricity usage by 19% and reduced peak demand by 18%.

Linking policies and industries to expand implementation impact
As a dual member of RE100 and EV100, Delta aims to leverage its own practices to generate broader external impact. On the industry side, by implementing RE100, Delta not only advances its own sustainability goals but also drives transformation across its value chain, helping partners reduce Scope 3 emissions and enhancing overall competitiveness and collaboration. On the policy front, Delta has drawn on its own experience to raise discussions in Taiwan regarding 24/7 renewable energy matching, fostering related policy development. Delta has also independently developed a power-matching program and employs climate modeling to monitor electricity supply regularly. In addition, Delta promotes renewable electricity adoption among suppliers through education and training; in Thailand, it actively participates in research on power purchase agreement (PPA) regulations and engages in policy dialogue.

By deploying charging stations across its global factories, offices, and R&D centers, Delta has not only accelerated employee EV adoption but also improved the accessibility of charging infrastructure in surrounding communities. More importantly, through a three-pronged strategy of“renewable energy application, smart technology enablement, and innovative mechanism design,”Delta has effectively addressed challenges in the electrification of transport. This model contributes to building a low-carbon mobility ecosystem and guides society toward a net-zero future.

Delta's implementation of RE100 and EV100 demonstrates the company's commitment to energy transition and transportation electrification, reflecting corporate action in response to global climate challenges. Through continuous innovation and accumulation of influence amid challenges, Delta aspires to make a lasting contribution to global net-zero targets and intergenerational sustainability.

Note: This year, Climate Group invited Delta to write an article on the implementation of EV100, titled "Making employee charging smarter and more accessible? Integration of IT will be the key."

Delta aims to use 100% renewable electricity at its global operation sites by 2030 and is actively adopting renewable eletricity.
