Pokémon GO has launched its annual Sustainability Week event, running from April 14th to April 20th, 2026. The event introduces a notable debut: Silicobra, the snake Pokémon from Galar, alongside Sandaconda. A significant draw is the Galarian Corsola variant, sporting pink sunglasses, which can also appear in its shiny form, making it a prime target for collectors.
The event's core revolves around a tiered GO Pass system, offering free and deluxe versions with escalating rewards as players complete specific tasks. This pass, automatically distributed to players on April 14th at 10:00 a.m. local time, unlocks bonuses such as increased experience points from spinning PokéStops and reduced egg-hatching distances. All GO Pass rewards must be claimed by April 22nd at 8:00 p.m. local time.
Event Highlights and New Additions
Sustainability Week focuses on environmental themes, with boosted spawns of nature-aligned Pokémon. Field Research tasks are central to progression, rewarding players with item bundles, Pokémon encounters, and points towards the GO Pass.
