Acknowledging SunPower Corp.

"SunPower innovates relentlessly to deliver industry-leading solar technology to residential, commercial and utility customers worldwide, while ensuring we maintain a light footprint and give back to communities globally," said Marty Neese, SunPower Chief Operating Officer. "Our holistic approach to sustainability and corporate social responsibility proves that solar companies, like SunPower, can be as sustainable as the clean, renewable energy their products deliver."

Through the Sustainable Business Award, the Guardian joins a list of third-party organizations validating SunPower's sustainable business practices. In April 2015, the U.S Patent and Trademark Office granted SunPower the Patents for Humanity award, recognizing the company's use of patented technology for social good.
