Greg Abel (pictured), 58, is a vice-chairman at Berkshire Hathaway whose work helped build up the energy side of the conglomerate, which owns companies including Duracell and Dairy Queen and has stakes in the likes of Coca-Cola and Apple. Abel has been working for the company since 1999, and since 2018 he's been in a vice-chairman role, overseeing areas such as railway companies, utilities, manufacturers, retailers and car dealerships according to reports by the Guardian. And Buffett has been full of praise for Abel's work, describing how “he does a far better job of that than I was doing previously.” Abel was the one to answer questions about the company's response to climate change at the meeting on Monday.
Another vice-chairman, Ajit Jain, who oversees the investment company's re-insurance operations, was rumoured to be a potential candidate for the CEO role. However, Jain is a decade older than Abel, and Buffett has indicated to CNBC that Abel's age was part of the decision, stating that "the likelihood of someone having a 20-year runway though makes a real difference."
