Sustainability week is returning to Pokémon Go with a chance to complete research tasks, participate in events and catch new Pokémon.

One new face making its way into the game is Oranguru, the Sage Pokémon, which originally appeared in the seventh generation titles Pokémon Sun and Moon.

There’s also a chance to capture a “shiny” variant of Cherubi, a grass-type Pokémon that’s harder to find than its original counterpart.

A themed “collection challenge” is also part of the event and if players can complete it before the event ends on 25 April, then they will have a chance to secure some hefty rewards.

To find out how to capture the new Pokémon, complete the weekly challenges and research tasks, keep reading the rest of the article below.

‘Pokémon Go’ sustainability week research task encounters

Players can collect field research tasks for sustainability week by spinning PokéStops. The tasks don’t need to be completed during sustainability week but they will contribute to the weekly challenge, so they are worth doing before the event ends on 25 April.

Encounter with Trubbish (catch three Grimers)
Silver pinap (catch three Trubbish)
Encounter with Turtwig, Snivy or Chespin (catch five grass-type Pokémon)
Encounter with Cherubi (walk 1km)

‘Pokémon Go’ sustainability week community day event

The community day event will take place on Saturday 23 April 2022 between 10:00 am to 8:00 pm local time.

During this period, there will be timed research available. Each phase will require you to walk 1km, and doing so will reward you with an encounter from Cherubi or its shiny variant.

For every player who walks 5km during the community day, Niantic and Ecosia will plant a tree (up to 100,000 trees) in total.
