A green bond is a type of fixed-income instrument with proceeds allocated to fund projects with environmental
benefits. Our subsidiary Arizona Public Service issued its inaugural green bond in September 2020. Through this
offering, we issued $400 million, which can be used to support projects such as renewable generation, energy
storage, energy efficiency programs, climate change mitigation and clean transportation.
