Delta announced in March 2021 that it had joined the RE100, a global renewable electricity initiative, and had pledged to achieve the goal of 100% renewable electricity and carbon neutrality by 2030 for all of Delta's global locations. We are the first company in Taiwan's high-tech manufacturing industry to commit to achieving the RE100 target by 2030.
Delta's operations are located across more than 30 countries on five continents and we will focus on independent energy conservation, self-generated power, and investment in renewable power plants. We use power purchase agreements (PPA) for the direct purchase of renewable electricity, green electricity products, and unbundled energy attribute certificates (unbundled EACs) for certain operations to meet the commitment targets.
In 2023, the use of renewable electricity at global operation sites reached 76%, which was higher than the annual target. We also enhanced data quality through introducing ISAE 3000 verification for the first time.
