Berkshire Hathaway Inc shareholders on Saturday overwhelmingly rejected six proposals addressing environmental and social policy issues at Warren Buffett's conglomerate, all of which the billionaire investor and his board opposed. By margins of more than 4-to-1, shareholders at Berkshire's annual meeting voted against two proposals that the company's insurance and energy operations disclose more about their efforts to address climate change including greenhouse gas emissions. They also turned down a proposal for more disclosure about efforts to promote diversity, equity and inclusion in the workplace.
