12/09/2020

Pinnacle West has been recognized for leadership in corporate sustainability by global environmental non-profit CDP, securing a place on its prestigious ‘A List’ for a second consecutive year for tackling climate change, as well as acting to protect water security.

Pinnacle West is shown as one of only four electric utilities worldwide that achieved a double ‘A’, out of 5,800-plus businesses that were scored based on data submitted through CDP’s questionnaires in 2020.

Through significant demonstrable action on climate change and water security risks, Pinnacle West is leading on corporate environmental ambition, action and transparency worldwide.

Arizona Public Service (APS), the principal subsidiary of Pinnacle West, has set a bold aspirational goal to provide its customers with 100% clean, carbon-free electricity by 2050. In support of this goal, APS is adding battery energy storage to its utility-scale solar plants in the state, helping provide “solar after sunset” to homes and businesses in Arizona. Additionally, APS recently signed a power purchase agreement renewable for 200 megawatts of wind energy that will contribute to our diverse and increasingly clean energy mix.

Pinnacle West also is committed to preserving the long-term quality and availability of water resources. Its water resource strategic plan ensures sufficient long-term water resources for its generating assets and promotes effective, sustainable water supplies. The company reduced groundwater use in 2019 by 22% compared to a 2014 baseline—exceeding the goal of a 14% reduction.

“This recognition from CDP underscores our commitment and actions to create a sustainable energy future for Arizona,” said Ann Becker, APS Vice President of Sustainability. “We operate our business in the water-constrained desert Southwest, giving us a unique perspective on the importance of water security and maximizing our use of clean energy resources like solar."

CDP’s annual environmental disclosure and scoring process is recognized as the gold standard of corporate environmental transparency. In 2020, over 515 investors with over $106 trillion in assets and 150-plus major purchasers with $4 trillion in procurement spend requested companies to disclose data on environmental impacts, risks and opportunities through CDP’s platform. Over 9,600 responded – the highest ever.

CDP uses a detailed and independent methodology to assess these companies, allocating a score of A to D- based on the comprehensiveness of disclosure, awareness and management of environmental risks and demonstration of best practices associated with environmental leadership.

Paul Simpson, CEO of CDP, said: “We extend our congratulations to all the companies on this year’s A List. Taking the lead on environmental transparency and action is one of the most important steps businesses can make, and is even more impressive in this challenging year marked by COVID-19. The scale of the risk to businesses from climate change, deforestation and water insecurity is enormous, and we know the opportunities of action far outweigh the risks of inaction. Leadership from the private sector will create an ‘ambition loop’ for greater government action and ensure that global ambitions for a net zero sustainable economy become a reality. Our A List celebrates those companies who are preparing themselves to excel in the economy of the future by taking action today.”
