Former New York City Mayor Michael Bloomberg is slated to become the United Nations special envoy for cities and climate change, according to Reuters.
Secretary General Ban Ki-moon could make the announcement as early as Friday, according to sources cited in Reuters.
The billionaire is chairman of the C40 Climate Leadership Group, a group of cities dedicated to combating climate change.
While mayor, he set out a goal of reducing greenhouse emissions in the city by 30 percent in the next two decades with a series of sustainability initiatives.
Bloomberg, an independent, also cited climate change as his reason for a surprise endorsement of President Obama late in the last election. At the time, he said that the effects of Hurricane Sandy brought into light the issue of global warming.
“Our climate is changing,” he said at the time. “And while the increase in extreme weather we have experienced in New York City and around the world may or may not be the result of it, the risk that it might be — given this week’s devastation — should compel all elected leaders to take immediate action.”
Bloomberg was first elected in 2001. Mayor Bill De Blasio (D) replaced him earlier this month.
