WASHINGTON _ As mayor of New York, Michael Bloomberg turned the city's iconic yellow taxicabs into hybrids, expanded bike lanes and raised floodwalls against worsening storms.
As a presidential candidate, he has touted his role as one of the largest climate philanthropists in the world, giving away hundreds of millions of dollars to help shut down dirty coal plants and promote clean energy.
And his campaign believes his largesse on such a priority issue for Democratic voters can make up for some of the more controversial policies from his past.
