“Stephen brought together the corporate policy team, and his wealth of knowledge will now continue to guide API’s work across the entire oil and natural gas industry value chain as we navigate the current environment and future challenges, and Aaron’s leadership will continue to be instrumental in helping shape our industry’s work on corporate issues ranging from climate and ESG to tax, trade and operational security.”

“I’m proud to now support the development and integration of all our policy teams here at API and I’m looking forward to continuing to help shape and advance industry priorities, from ensuring that American families and businesses have a reliable supply of energy to reducing emissions from industry operations,” Comstock said.

Padilla has 20 years of experience leading work in corporate international affairs and in the environmental and social dimensions of corporate sustainability. Over the course of his career, he has worked in 30 countries across six continents.
