Pokémon Go is hosting its yearly “Sustainability Week” event celebrating Pokémon that make the planet green. During the event, tons of grass- and water-type Pokémon will be spawning and there’s a handful of other event perks. The event runs from April 20-26.
There are lots of perks that involve your buddy Pokémon. They’ll stay on the map longer after feeding it, earn hearts via walking faster, and bring back gifts more often if you’re at Great or higher with them.
Special Research tasks that reward you with the mythical Pokémon Shaymin also launched alongside this event. You can see all the steps and rewards in our “Grass and Gratitude” Shaymin research guide.
This event also adds the Bounsweet family to the game, as well as shiny forms for the Drilbur family, which you may find if you’re lucky.

Below, we’ve listed out all the perks for Pokémon Go’s “Sustainability Week” 2023 event.
