Delta Air Lines is one of the largest and most successful airlines in the United States of America. The company operates in the Full Service Airline sector, providing a wide range of services to its customers, including domestic and international flights, cargo transportation, and other travel-related services. Delta Air Lines is committed to sustainability and has taken several measures to reduce its carbon footprint and promote decarbonisation in the aviation industry.

One of the key areas of focus for Delta Air Lines is corporate energy management. The company has implemented several initiatives to reduce its energy consumption and promote energy efficiency. For example, Delta Air Lines has invested in energy-efficient technologies and equipment, such as LED lighting, high-efficiency HVAC systems, and energy-efficient aircraft. The company has also implemented energy management systems to monitor and control energy consumption in its facilities and operations.

In addition to energy efficiency, Delta Air Lines is also committed to renewable energy. The company has set a goal to source 50% of its electricity from renewable sources by 2025. To achieve this goal, Delta Air Lines has implemented several renewable energy projects, including the installation of solar panels at its headquarters in Atlanta and the purchase of renewable energy certificates (RECs) to offset its carbon emissions. The company has also signed several corporate power purchase agreements (PPAs) to support the development of new renewable energy projects.

Corporate PPAs are long-term contracts between a company and a renewable energy developer, under which the company agrees to purchase a fixed amount of renewable energy at a predetermined price. Delta Air Lines has signed several corporate PPAs to support the development of new wind and solar projects in the United States. For example, in 2019, the company signed a 15-year PPA for 75 MW of wind power from a new wind farm in Texas. The wind farm is expected to generate enough energy to power more than 20,000 homes and will help Delta Air Lines achieve its renewable energy goals.

Decarbonisation is another key area of focus for Delta Air Lines. The aviation industry is one of the largest emitters of greenhouse gases, and reducing carbon emissions is essential to address climate change. Delta Air Lines has set a goal to achieve carbon neutrality by 2030, and the company has implemented several measures to reduce its carbon footprint. For example, the company has invested in more fuel-efficient aircraft and implemented operational improvements to reduce fuel consumption. Delta Air Lines has also implemented a carbon offset program to offset its remaining emissions, and the company is exploring new technologies and fuels to further reduce its carbon footprint.

Overall, Delta Air Lines is a leader in sustainability in the aviation industry. The company has implemented several initiatives to reduce its energy consumption, promote renewable energy, and achieve carbon neutrality. Delta Air Lines has set ambitious goals for decarbonisation and is committed to working with its partners and stakeholders to address climate change. As the aviation industry continues to evolve, Delta Air Lines will continue to innovate and lead the way in sustainability.
