Methane leakage is one of many issues at the forefront today over how the oil and gas industry is engaging in the clean energy transition. Importantly, this industry includes not only some of the better-known energy companies, but also many national oil companies. Collectively they produce about half the world’s oil and gas. During last year’s COP28, these companies committed to cutting methane emissions and working towards decarbonizing the industry. But the energy transition for these companies is a delicate balance, as they are responsible for generating revenue and ensuring energy security for their countries.  So, how will global pledges to decarbonize impact the oil and gas industry? What is the role for cleaner fuels like hydrogen in meeting growing energy demand? How much progress is being made to curb methane emissions? And what is the role of national oil companies in the transition?  This week host Jason Bordoff talks with Mark Brownstein about the importance of reducing methane emissions and what the transition looks like for national oil companies.  Mark is the senior vice president of energy transition at the Environmental Defense Fund. He has been with EDF for almost two decades, working to halt the rise of global oil and gas emissions and accelerate the transition away from fossil fuels. Before joining EDF, Mark worked for Public Service Enterprise Group, a large electric and gas utility holding company in the U.S. He has also taught energy policy at Columbia University’s School of International and Public Affairs.
