What can you catch during Sustainability Week?

Sustainability Week is the latest event in Pokémon Go and is inspired by the need to safeguard our environment.

During this week, you'll be able to complete the Sustainability Week research quest, while also completing exclusive field research tasks to earn encounters with Pokémon connected to the environment.

This event also sees the release of two Gen 6 Pokémon - Binacle and Barbaracle - into Pokémon Go.

Below lies all the challenges and rewards for the Sustainability Week research quest. This section does contain spoilers though, so, if you want to remain surprised, we recommend skipping it.

The Sustainability Week research quest is a timed research quest, which means you must complete it before the week ends if you wish to collect all of the rewards.

Thank you to SilphScience from reddit for the help with this information!

Aside from the research quest and tasks, the focal point of Sustainability Week is the release of Binacle and, it's evolution, Barbaracle. Despite having, in this author's opinion, awful designs, these two Pokémon are the latest Gen 6 releases, so you'll want to catch them for your Kalos Pokédex.

Binacle and Barbacle can now be added to your Pokédex!

Alongside Binacle, the following Pokémon have been given boosted spawns during the event:

  • Seel
  • Grimer
  • Sunkern
  • Phanpy
  • Grotle
  • Drilbur
  • Trubbish
  • Ferroseed
  • Binacle

If you're lucky, you might even find a shiny Trubbish!

The pool for 5km eggs has also been altered for Sustainability Week, with the following Pokémon being hatchable from any 5km egg you collect during the event:


Tier 1:

  • Diglett
  • Goldeen
  • Finneon

Tier 2:

  • Cherubi
  • Drilbur

Tier 3:

  • Tangela
  • Budew

Finally, as always, there will be a new range of Pokémon in raids, including Therian Landorus in five-star raids, while Mega Venusaur, Abomasnow and Lopunny will all be available in Mega Raids.

The Season of Legends is here! Current activities include the Luminous Legends X event, which introduces Gloomy, Spritzee and Swirlix, Xerneas and the Rainly Lure. We've also recently seen a level cap increase - including the addition of XL Candy, boosts to some XP sources and the addition of Platinum Medals.

Sustainability Week dates and time in Pokémon Go

Pokémon Go's Sustainability Week is in partnership with the Niantic Sustainability Campaign and is themed around protecting the environment, because global warming is real.

Both the timed research quest and exclusive Sustainability Week field research quests are only available during this specific event, which runs from Tuesday, 20th April at 10am (local time) to Sunday, 25th April at 8pm (local time).


The Sustainability Week research quest is constructed out of three steps, which each contain three individual challenges. You'll be rewarded for each challenge and overall quest steps you complete, but, since this is a timed research quest, you'll need to complete the research before the event ends if you want to earn every reward.

Enjoy Sustainability Week and don't litter!
