San Diego County Regional Airport Authority (SDCRAA) is a public agency that operates San Diego International Airport (SAN), which is located in the heart of San Diego, California, United States of America. The airport serves more than 25 million passengers annually, making it one of the busiest airports in the country. SDCRAA is committed to providing a safe, efficient, and sustainable airport experience for its passengers, employees, and community. In line with this commitment, SDCRAA has implemented various initiatives to reduce its carbon footprint and transition to renewable energy sources.

Decarbonisation is a key focus area for SDCRAA. The airport authority recognizes that aviation is a significant contributor to greenhouse gas emissions and is committed to reducing its carbon footprint. To achieve this, SDCRAA has set a goal to achieve net-zero carbon emissions by 2035. To achieve this goal, SDCRAA has developed a comprehensive decarbonization plan that includes various initiatives such as energy efficiency measures, renewable energy adoption, and electrification of ground transportation.

One of the key initiatives undertaken by SDCRAA to achieve decarbonization is the adoption of renewable energy sources. The airport authority has signed a 20-year power purchase agreement (PPA) with Enel Green Power North America, Inc. to purchase 44 megawatts of renewable energy from the Azure Sky Wind Project in Kansas. The project is expected to generate enough renewable energy to power the equivalent of 17,000 homes annually and offset approximately 60% of the airport's electricity consumption. The corporate PPA is a significant step towards achieving SDCRAA's decarbonization goal and reducing its carbon footprint.

In addition to the corporate PPA, SDCRAA has also implemented various energy efficiency measures to reduce its energy consumption. The airport authority has installed energy-efficient lighting, heating, and cooling systems, and has implemented a comprehensive energy management system to monitor and optimize energy usage. SDCRAA has also implemented a solar panel system on the airport's parking garage, which generates approximately 3.3 million kilowatt-hours of renewable energy annually and offsets approximately 10% of the airport's electricity consumption.

Corporate energy management is another key focus area for SDCRAA. The airport authority has developed a comprehensive energy management program that includes energy audits, energy benchmarking, and energy performance tracking. The program is designed to identify energy-saving opportunities and optimize energy usage across the airport's facilities. SDCRAA has also implemented a green building policy that requires all new construction and major renovations to meet LEED certification standards, which promote energy efficiency and sustainability.

SDCRAA's commitment to sustainability extends beyond its own operations. The airport authority has partnered with airlines, ground transportation providers, and other stakeholders to promote sustainable practices across the airport's supply chain. SDCRAA has implemented a green concessions program that encourages airport vendors to adopt sustainable practices such as reducing waste, conserving water, and using eco-friendly products. The airport authority has also partnered with the San Diego Gas & Electric Company to provide incentives for ground transportation providers to switch to electric and hybrid vehicles.

In conclusion, SDCRAA is a leading airport operator in the United States that is committed to sustainability and decarbonization. The airport authority has implemented various initiatives to reduce its carbon footprint, including the adoption of renewable energy sources, energy efficiency measures, and electrification of ground transportation. SDCRAA's commitment to sustainability extends beyond its own operations and includes partnerships with airlines, ground transportation providers, and other stakeholders to promote sustainable practices across the airport's supply chain. SDCRAA's efforts to achieve decarbonization and sustainability serve as a model for other airports and organizations to follow.
