GreeNYC is New York City’s environmental initiative, now in its eighth year. Since 2007, HunterGatherer has helped the Mayor’s Office grow GreeNYC into a multi-faceted campaign; encompassing seasonal print, outdoor, and television messages, as well as retail partnerships and targeted mini-campaigns.

The latest installment, the B.Y.O. (Bring Your Own) Campaign, has hit the streets! This summer Birdie is asking you to join the movement by bringing your own bag, mug, and bottle to help save waste. You can take the B.Y.O. pledge here.
