Not only are there event-exclusive field research tasks for you to find, but there’s a Sustainability Week Collection Challenge for you to complete. Sustainability Week 2022 also celebrates the release of Oranguru - a Gen 7 Pokémon - into Pokémon Go, so make sure you take the time to catch one. On this page: It’s important to note that two of the Pokémon listed below can only be found by using a Mossy Lure on a PokéStop during Sustainability Week 2022. Thankfully, there is a free Mossy Lure bundle available in the in-game shop during this event, so you don’t need to worry about purchasing one. Here are the Pokémon in the Sustainability Week 2022 Collection Challenge, along with how to find them:

Cherubi - In the wild, attracted to Mossy Lure and field research task (Catch 5 Grass-type Pokémon) Grimer - In the wild Gloom - Attracted to Mossy Lure Weepinbell - Attracted to Mossy Lure Trubbish - In the wild and field research task (Catch 3 Grimer) Grotle - In the wild and attracted to Mossy Lure

For completing this Collection Challenge, you’ll receive 10,000 XP, 15 Great Balls and a Meganium encounter. The Season of Mythical Wishes continues with the Winter Holiday event, which has brought Mega Glalie to Pokémon Go. Don’t forget to partake in the new Go Battle League season. Elsewhere, be sure to use Daily Adventure Incense for the chance of encountering Galarian Articuno, Galarian Zapdos and Galarian Moltres.
While these field research tasks can be saved and completed after the event ends, we recommend completing them during the event, because some of the Pokémon encounters you’re rewarded with will help you complete the Sustainability Week 2022 Collection Challenge. Here are the Sustainability Week 2022 field research tasks:

Catch 3 Grimer reward - Trubbish encounter Catch 3 Trubbish reward - 1 Silver Pinap Catch 5 Grass-type Pokémon reward - Turtwig, Snivy or Chespin encounter Walk 1km reward - Cherubi encounter Walk 3km reward - Phantump encounter Power up Pokémon 5 times reward - 50 Mega Venusaur Energy or 50 Abomasnow Energy

Thank you to SilphScience from reddit for the help with this information! The main attraction of this event is the release of Oranguru - a normal and psychic-type Pokémon from Gen 7. Keep an eye out for this Pokémon, so you can add another entry to your Alola Pokédex. This event also sees the release of shiny Cherubi and, if you find one, you’ll be able to evolve it into a shiny Cherrim. Good luck shiny hunting! There will also be a timed research quest running from 10am to 8pm (local time) on Saturday, 23rd April, which will reward you with a Cherubi encounter. This timed research quest coincides with the Stufful Community Day, which celebrates the release of Stufful into Pokémon Go. Throughout Sustainability Week 2022 a number of Pokémon will be spawning more frequently in the wild:

Venusaur Oddish Grimer Turtwig Grotle Cherubi Trubbish Ferroseed Phantump Oranguru

A selection of Pokémon will also be attracted any Mossy Lure placed during Sustainability Week:

Gloom Alolan Diglett Weepinbell Chikorita Bellossom Nincada Grotle Cherubi Sewaddle

Finally, any 7km egg you collect during Sustainability Week 2022 will have the following egg pool:

Alolan Diglett Larvitar Oranguru

Hope you enjoy Sustainability Week 2022!
