The self-made billionaire and former mayor of New York City, Michael Bloomberg, has his sights set on one last election. Dubbed by the New York Times as a media titan who’s aiming for “mayor of the world,” Bloomberg’s final, empty bucket list box is a vacant space he’s saving for the betterment of the world.

At 72, Bloomberg made a promise to part with his $32.8 billion fortune before he leaves the earth. He’ll do that by reducing smoking rates in Turkey and Indonesia, wiping away obesity levels in Mexico, organizing environmentally friendly and efficient delivery services on a global scale, reducing traffic in Istanbul and Rio de Janeiro, improving rod safety in Kenya and India, and preventing childbirth death and complications for soon-to-be mothers in Tanzania. These causes, and so many more, provide the DNA of Bloomberg Philanthropies, a nine-year-old foundation with projects underway in more than 95 countries.

Bloomberg Philanthropies, first started in 2006, was built on Bloomberg’s need, and belief, in effecting change. In an interview with the Times, he said, “If there is one thing that I learned from 12 years in government, is that you can effect change, pull people together and face big societal problems.”

In his mind, the former mayor’s clock may be fast ticking, but the legacy he’s unfolded since leaving office has staying power.
