Ralph Izzo, chairman, president and CEO of Public Service Enterprise Group (PSEG), has discussed the company's approach to carbon emissions and energy policy. In a 2019 presentation, Izzo stated that the reduction in carbon emissions over the previous decade was largely driven by the economic shift from coal to low-cost natural gas, rather than policy alone. He said that without a price on carbon or other environmental incentives, carbon emissions would likely rise, and that continued progress would require changing the cost structure of commodities. Izzo also noted that PSEG had shut all its coal plants and described the company's efforts to improve transparency around environmental, social, and governance (ESG) ratings, while cautioning that he prefers to be judged by actions rather than statements. In a 2008 lecture, Izzo discussed the need for investment in a range of energy technologies, including energy efficiency, nuclear, solar, and wind, and said that some options would require higher energy costs to implement but would yield benefits in mitigating climate change and improving air quality. He also addressed the electrification of transportation, stating that PSEG aimed to assist with fleet purchases and public charging infrastructure, and noted that he had spoken with General Motors chairman Rick Wagoner about supporting the company's electric vehicle efforts.
