To encourage players to participate, Niantic will be offering global rewards to both Pokemon GO and Ingress players based on the number of players involved. There are three tiers in all: 2,000, 5,000, and 7,000.

If 2,000 players attend the cleanup, Pokemon GO players will see an increased amount of Ground-type Pokemon. Ingress players will see increased chances of obtaining heatsinks, multihacks, shields, and power cubes.

At 5,000 players, Pokemon GO will offer a Shiny Digglet and increase the appearance of Ground-type Pokemon even more. Ingress will offer players 2x AP linking.

If the cleanup hits the 7,000-player mark, Pokemon Go players will be offered double Stardust and Candy for Event spawns while Ingress players will get double AP fielding.

Last year, Niantic teamed up with Playmob, a gaming-for-good platform, to host 68 events across the world and clean up 6.5 tons of garbage.

This year, Niantic and Playmob have joined forces with 15 non-profit organizations (NGOs) to host even more cleanups, and the companies are inviting all players to participate. 

Those interested can sign up to host a group via the Earth Day Clean up website. Players can also sign up individually, to participate solo, by tagging the Niantic Labs Twitter account using the hashtag #AugmentingReality.

Currently, the event’s website shows cleanups registered all around the world. Those wanting to participate can use the search option to find events near them.
