                Major Index Lists PG&E in the Top Ten Among S&P 500 and Global 500 Companies

                (San Francisco) –The Carbon Disclosure Project (CDP), an independent organization that
                maintains the largest global database of corporate climate change information, has listed PG&E
                Corporation (NYSE:PCG) as one of the leading companies in the world when it comes to openly
                sharing public information on greenhouse gas emissions, emissions reduction targets, and the
                implications of climate change for its business. The company ranked in the top ten on the Carbon
                Disclosure Leadership Index for both the S&P 500 and the Global 500, and is one of only four U.S.
                utilities to make the global listing. PG&E tied for first place as the CDP’s top-ranked utility

                The indices, compiled by PricewaterhouseCoopers (PwC) on behalf of CDP, provide an
                evaluation tool for institutional investors seeking to understand and manage risk associated with
                climate change. CDP is currently backed by 475 institutional investors with assets of more than $55
                trillion who sent the survey to 3,700 of the world's largest companies.

                “We’re pleased to be recognized for PG&E’s extensive reporting on the risks and
                opportunities that climate change presents to our business,” said Steve Kline, PG&E Corporation’s
                Chief Sustainability Officer. “We believe it’s critical that investors, customers, policy makers and
                other stakeholders have access to information that allows them to assess and understand the
                relationship between our business and the challenge of climate change. We’re committed to
                providing the information necessary to make this possible.”

                PG&E was among the earliest companies to voluntarily quantify and report greenhouse gas
                emissions, which is an essential first step in the longer-term effort to effectively and efficiently
                address this challenge. The company was a charter member of the California Climate Action
                Registry and, in 2002, became the first investor-owned utility in California to voluntarily complete
                a third-party-verified inventory of its CO2 emissions. PG&E has participated in the Carbon
                Disclosure Project since 2005.
