GreeNYC is launching the B.Y.O. awareness campaign through bus, subway and digital ads, in radio public service announcements, and on billboards and Sanitation trucks reminding New Yorkers to bring reusable mugs, bottles and bags when they’re on the go. GreeNYC is also working with small businesses in all five boroughs, in partnership with the Department of Small Business Services, to encourage them to post signage demonstrating their commitment to improving the environment and remind customers to bring their own mugs, bottles and bags when visiting.
