On Nov. 23, 2001, under the headline “Michael Bloomberg’s Environmental Agenda,” this column began, “The stunning victory of Michael R. Bloomberg in the Nov. 6 election means that City Hall will be occupied by a man who has no record in environmental affairs.” The column went on to summarize the promises found in Bloomberg’s campaign literature and other statements.

Now with Mayor Bloomberg’s term about to end and Bill de Blasio’s about to begin, we can compare the outgoing mayor’s accomplishments to his promises, and also look at what the incoming mayor has pledged.
