As Public Advocate, Green first proposed the 311 complaint help line that Mayor Bloomberg later implemented. He wrote laws that matched small donations with multiple city funds, created the Voter Commission, upheld the legality of the Independent Budget Office, barred stores from charging women more than men for the same services, and that prohibited companies from firing female employees merely because they were victims of domestic violence. He started the City's first web site, NYC.Gov, which he later gifted to City Hall, where it is still in use.
