Decarbonisation is a key focus area for VTA. The agency is committed to reducing its greenhouse gas emissions and promoting sustainable transportation options. VTA has set a goal of reducing its carbon footprint by 80% by 2040, which is in line with the state of California's climate goals.

The agency is also exploring the use of energy storage systems to reduce its reliance on the grid during peak demand periods.

Corporate PPAs are an important tool for VTA to achieve its sustainability goals. The agency has entered into several PPAs with renewable energy providers to purchase clean energy to power its operations. These agreements allow VTA to lock in a fixed price for electricity, which helps to reduce its energy costs and promote renewable energy development.

Renewable energy is a key component of VTA's sustainability strategy. The agency is committed to increasing its use of renewable energy sources, such as solar and wind power, to power its operations. VTA has installed solar panels on the roofs of several of its facilities, which generate clean energy and reduce the agency's reliance on the grid. The agency is also exploring the use of renewable energy to power its electric buses and light rail vehicles.

In addition to these initiatives, VTA is also committed to promoting sustainable transportation options for its riders. The agency has implemented several programs to encourage the use of public transportation, such as discounted fares for low-income riders and bike-sharing programs. VTA is also exploring the use of autonomous vehicles to provide last-mile transportation options for riders.

Overall, VTA is a leader in promoting sustainability and reducing its carbon footprint. The agency's commitment to decarbonisation, corporate energy, corporate PPAs, and renewable energy is commendable and serves as a model for other public transportation agencies. By investing in sustainable transportation options and promoting renewable energy, VTA is helping to create a cleaner and more sustainable future for the residents of Santa Clara County.
