我们的目标是让人们拥有更加可持续的旅行未来。到2050年实现航空运营净零碳排放是我们的最终目标。但是，全球航空业是难以实现净零碳排放的行业，这意味着该行业先天就难以脱碳。Our multi-pronged approach to make progress toward this goal focuses on improving the efficiency of our fleet, innovating aircraft operations, and increasing the use of Sustainable Aviation Fuel (SAF) to reduce our emissions.
In the short term, we are working to transition to a more fuel-efficient fleet and enhancing operational efficiency to reduce jet fuel burn. 长期努力包括用可持续航空燃料（SAF）取代占比越来越高的传统喷气式飞机燃料，并与创新者合作彻底改变航空业。
可持续航空燃料（SAF）是脱碳飞行的关键手段，它能将喷气式飞机燃料的生命周期排放量减少多达80% We aim to procure over 400 million gallons of SAF annually by the end of 2030, supporting our goal of 10% SAF utilization. In 2024, we more than tripled SAF deliveries compared to 2023, for a total of over 13 million gallons.
We focus on building our fleet to improve fuel efficiency by upgauging our planes and replacing retiring aircraft with next-gen models. Aircraft added to our fleet since 2019, including 38 delivered in 2024, are on average 28% more fuel efficient per seat mile than those they replaced. Initiatives like better flight routing, onboard efficiencies, and cutting-edge technologies saved approx. 44 million gallons of jet fuel in 2024 compared to what we would have used in 2019 without these improvements.
Launched in 2023, the Delta Sustainable Skies Lab is a first-of-its-kind airline innovation lab focusing on research, design and testing to drive progress toward our climate goals. The Lab inspires disruptive industry innovation and aims to scale new technologies and actions to help Delta reach its sustainability goals. Partners include JetZero, whose blended-wing body aircraft aims to reduce carbon emissions by up to 50% compared to today.
我们对可持续发展的承诺不仅限于我们的航班运营。我们还致力于减少浪费，向顾客提供更多可持续的产品，尽量减少地面运营对环境的影响，并积极与供应链合作，共同推进这些工作。We’re eliminating millions of pounds of plastic onboard annually and incorporating more products that are recyclable onboard our aircraft, which can help us reduce our environmental impact, enhance the customer experience, and improve our operations.
