"CDP honoring Delta’s climate change and water security endeavors with top scores for the third time is a major milestone for us,” said Jesse Chou, Delta’s chief sustainability officer. “In 2023, Delta became a member of the Taskforce on Nature-related Financial Disclosures (TNFD) Forum and completed the first biodiversity risk assessment of Delta's sites. In January of this year, Delta also became an early TNFD adopter. Externally, we have incorporated our climate transition plan into our annual shareholders’ meeting and quarterly investor conferences agendas. Internally, we have completed a GHG inventory for 15 categories under Scope 3 to identify key areas for future emissions reduction."

Delta has been actively implementing climate change mitigation, the company said. Since 2021, Delta has included the percentage of renewable electricity in its performance indicators for senior executives. In 2021, Delta also implemented an internal carbon-pricing scheme of $300 per metric ton of CO₂ emissions, which is invested in energy-saving and carbon-reduction projects, as well as in the development of carbon-negative technologies and low-carbon innovation, the company said.

Delta has also collaborated with the National Museum of Marine Science & Technology to establish Asia's first zero-carbon coral conservation center. Through the Task Force on Climate-related Financial Disclosures framework, Delta assesses climate change risks and opportunities, translating them into operational strategies and actively exploring opportunities such as electric vehicles, energy storage, and hydrogen energy, the company said.

Although Delta is not a heavy water user, the company has established strategic water goals and methodologies, implementing them in daily operations, the company said. In 2022, Delta conducted a water risk assessment for its global sites and formulated a water resource policy across the entire organization. The company also assessed its tier-1 suppliers and incorporated those results into decision-making.

In 2022, Delta achieved a 12.8% reduction in its global water productivity intensity, with its total water withdrawal and water discharge decreasing 4% despite the higher revenue delivered, the company said.

CDP's annual assessment and scoring process is recognized as an important standard for environmental transparency. In 2023, more than 740 investors and more than 300 major procurement organizations, with a combined spending of $6.8 trillion, requested that companies disclose information about their environmental impacts, risks, and opportunities through the CDP platform.

More than 21,000 companies, the highest number ever, participated in the assessments for the latest CDP reports. Delta has been included in the CDP A List for Water Security Management for four consecutive years and has received leadership scores in the Climate Change category for seven years.
