Amid the accelerating global transition toward net zero, the share of renewable electricity usage has become an important indicator of a company’s sustainability competitiveness. Delta officially joined the RE100 initiative in 2021, committing to achieving 100% renewable electricity usage across its global operation sites by 2030. Since then, the Company has continued to advance energy transformation through concrete actions. By the end of 2025, Delta achieved significant progress in its renewable energy deployment, with renewable electricity accounting for 91% of total consumption across its global operations. This milestone not only marks substantial progress toward its 2030 target, but also signifies a new phase in the Company’s energy transition journey.

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

RE100 is a global renewable energy initiative jointly launched in 2014 by The Climate Group and CDP (formerly the Carbon Disclosure Project). It brings together influential companies committed to sourcing 100% renewable electricity between 2020 and 2050, aiming to accelerate the global energy transition. At the early stage of joining, Delta set an internal interim target of achieving 80% renewable electricity by 2025. According to its ESG disclosures over the years, Delta's global renewable electricity ratio increased from 63% in 2022, to 76% in 2023, and further to 84% in 2024, demonstrating a stable and rapid growth trend. By 2025, the ratio surpassed 90%, exceeding its interim target ahead of schedule.

Alongside its expansion of renewable electricity usage, Delta has also shown leading performance in carbon reduction. In 2025, Delta’s Science Based Target (SBT) Scope 1 and Scope 2 carbon emissions were reduced by 67.4% compared to the base year, significantly outperforming the original target. This achievement reflects not only reduced emissions through the procurement of green electricity, but also Delta's comprehensive efforts to reduce emissions at the source. These include equipment efficiency improvements, process optimization, intelligent energy management, and the adoption of green buildings to enable low-carbon operations.

Delta's RE91 achievement is supported by the integrated application of a diversified renewable energy strategy. Overall, Delta advances RE100 through four major approaches:
1.    Deploying solar power systems and prioritizing self-generated, self-consumed electricity. 
2.    Signing long-term green power purchase agreements (PPAs). 
3.    Procuring green power products. 
4.    Supplementing demand, when necessary, with unbundled Environmental Attribute Certificates (unbundled EACs). 

Through regional planning and flexible deployment across its global locations, Delta has achieved RE100 milestones in operations spanning 32 countries, including Taiwan, China, Northeast Asia, the Americas, and Europe as of 2026. Compared to other regions, the renewable energy landscape in Taiwan presents greater challenges. Limited green electricity supply and relatively higher costs of renewable energy, coupled with stringent requirements on integrated electricity certifications and electricity consumption matching mechanisms in the market, make it more difficult for the Company to obtain compliant green electricity. In addition, compared with the globally advocated concept of 24/7 carbon-free electricity (24/7 CFE), Taiwan requires electricity generation and consumption to be matched every 15 minutes, which poses a significant challenge to the Company's energy management capabilities.

In response to these challenges, Delta has implemented an internal carbon pricing mechanism to support its transition efforts. The Company has also developed a renewable energy matching digital platform, integrating data analytics and AI algorithms to evaluate different combinations of energy sources, time periods, and cost structures, thereby optimizing procurement strategies and supporting the achievement of 24/7 carbon-free energy goals. Originally designed for internal operational management, this platform is now gradually being developed into an external service solution, helping other companies better plan their RE100 pathways and unlock new green business opportunities.

Delta has long emphasized that sustainability is not only a corporate responsibility, but also an important source of competitiveness. From the development of energy-efficient products and solutions, to carbon reduction practices in daily operations, and the strategic expansion of renewable energy, Delta continues to demonstrate through concrete achievements the key role of the electronics industry in the energy transition. The achievement of RE91 in 2025 not only represents a data breakthrough, but also marks an important milestone toward achieving the global RE100 target in 2030.

Looking ahead, Delta will continue to increase the ratio of high-quality, traceable, and compliant renewable energy usage, enhancing the energy resilience and intelligent management of its global sites. As industries worldwide move toward net zero, Delta is steadily advancing its green transformation and maintaining its position at the forefront of RE100 leadership.
