Sacramento International Airport (SMF) is a public airport located in Sacramento, California, United States of America. It is owned and operated by the Sacramento County Airport System, which is a department of the Sacramento County government. The airport serves as a gateway to Northern California and handles both domestic and international flights. In recent years, SMF has been actively working towards decarbonisation and incorporating renewable energy sources into its operations.

Decarbonisation is the process of reducing carbon emissions and transitioning to a low-carbon economy. The aviation industry is a significant contributor to global carbon emissions, and airports play a crucial role in reducing their carbon footprint. SMF has set a goal to become a carbon-neutral airport by 2045. To achieve this goal, the airport has implemented several initiatives to reduce its carbon emissions.

One of the initiatives undertaken by SMF is the installation of solar panels on the airport's roof. The airport has installed a 7.9 MW solar array, which is one of the largest airport solar installations in the United States. The solar panels generate enough electricity to power 80% of the airport's energy needs. The airport has also installed electric vehicle charging stations in its parking lots to encourage the use of electric vehicles.

Corporate energy is the energy consumed by a company in its operations. SMF has implemented several measures to reduce its corporate energy consumption. The airport has replaced its traditional lighting fixtures with LED lights, which are more energy-efficient. The airport has also installed energy-efficient HVAC systems and implemented a building automation system to optimize energy consumption.

Corporate power purchase agreements (PPAs) are contracts between a company and a renewable energy provider to purchase renewable energy. SMF has entered into a corporate PPA with a local solar provider to purchase renewable energy. The PPA will provide the airport with 30 MW of renewable energy, which is equivalent to the energy consumed by 6,000 homes. The PPA will help the airport reduce its carbon emissions and achieve its goal of becoming a carbon-neutral airport.

Renewable energy is energy derived from sources that are naturally replenished, such as solar, wind, and hydro power. SMF has incorporated renewable energy sources into its operations to reduce its carbon footprint. In addition to the solar panels installed on the airport's roof, the airport has also installed a 2 MW solar farm on its property. The solar farm generates enough electricity to power 400 homes and helps the airport reduce its reliance on fossil fuels.

In conclusion, SMF is a public airport located in Sacramento, California, United States of America. The airport is owned and operated by the Sacramento County Airport System and serves as a gateway to Northern California. The airport has set a goal to become a carbon-neutral airport by 2045 and has implemented several initiatives to reduce its carbon emissions.
