Complete guide to Pokemon Go Sustainability Week Timed Research tasks with strategic completion tips
Understanding Sustainability Week Timed Research
Pokemon Go’s annual Sustainability Week event brings exclusive timed research challenges with valuable rewards for dedicated trainers.
The 2023 Sustainability Week celebration introduces environmentally-themed content including new Pokemon appearances, special avatar items, and limited-time activities. Among these offerings, the timed research tasks provide structured objectives that reward players with exclusive encounters and useful items unavailable through regular gameplay.
Many trainers wonder whether investing time in these limited tasks delivers worthwhile returns. This comprehensive breakdown examines every requirement and reward across all research stages, plus strategic advice to maximize your efficiency during the event window.
Stage 1: Basic Sustainability Tasks
The initial stage introduces fundamental sustainability-themed activities with manageable requirements perfect for casual players.
- Use 5 Berries to help catch Pokemon – Drilbur encounter
- Feed your buddy 5 times – Pinap Berries reward
- Take 5 snapshots of your buddy – Trubbish encounter
Completion Rewards: 1000XP, 500 Stardust, 1 Star Piece
Pro Tip: Complete these tasks during normal gameplay sessions rather than dedicating special time. Use berries on high-flee-rate Pokemon to efficiently fulfill the requirement while improving catch rates. The Star Piece reward provides 50% bonus Stardust for 30 minutes – activate it before claiming stardust-heavy rewards in later stages.
Stage 2: Intermediate Challenges
Stage 2 increases the difficulty slightly while introducing more valuable rewards and rare Pokemon encounters.
- Use 7 Berries to help catch Pokemon – Trubbish encounter
- Earn 5 hearts with your buddy – Nabnab Berries reward
- Play with your buddy – Bounsweet encounter
Completion Rewards: 1500XP, 1000 Stardust, 1 Incense
Strategic Approach: The buddy heart requirement benefits from selecting a Pokemon that requires fewer kilometers per candy. Great buddies only need 2 hearts to earn candies while exploring. Coordinate your incense usage with the ‘Use an Incense’ task in Stage 3 to complete two objectives simultaneously. Bounsweet represents one of the newer Pokemon additions, making this encounter particularly valuable for completionists.
Stage 3: Advanced Sustainability Goals
This stage introduces more time-intensive requirements that benefit from advanced preparation and resource management.
- Use 9 Berries to help catch Pokemon – Drilbur encounter
- Earn 2 Candies exploring with your buddy – Grimer encounter
- Use an Incense – Bounsweet encounter
Completion Rewards: 2000XP, 1500 Stardust, 10 Razz Berries
Efficiency Methods: The candy-earning task works best with 1km buddy distance Pokemon like Magikarp or Feebas. Plan a walking route during incense activation to progress multiple objectives. Save the Razz Berries reward for later stages requiring berry usage. Grimer’s Alolan form may appear during this encounter, providing additional collection value beyond the standard variant.
Stage 4: Final Sustainability Milestones
The final stage presents the most challenging requirements but offers the most substantial rewards for dedicated completion.
- Use 5 Berries to help catch Pokemon – Binacle encounter
- Earn 3 Candies exploring with your buddy – Drilbur encounter
- Receive a Souvenir from your buddy – Bounsweet encounter
Completion Rewards: 2000XP, 2000 Stardust, 15 Ultra Balls
Optimization Strategy: Binacle represents a relatively rare Pokemon, making this encounter particularly valuable. The souvenir requirement depends on your buddy’s mood level – ensure your buddy is at least Great Buddy status and regularly fed to increase souvenir frequency. Ultra Balls provide excellent utility for catching rare spawns during the event. Consider using a Star Piece before claiming the 2000 Stardust reward for 3000 total Stardust.
Advanced Completion Strategies
Time Management Essentials
Sustainability Week runs from Thursday, April 20, 2023, at 10 AM through Wednesday, April 26, 2023, at 8 PM local time. With less than one week available, strategic time allocation becomes crucial. Prioritize tasks requiring walking distance early, as these cannot be rushed. Save quick-completion tasks like berry usage for the final days if needed.
Resource Optimization Techniques
Coordinate item usage across multiple tasks. Activate incense when you can walk continuously to progress both incense and candy-earning objectives simultaneously. Stack berry usage requirements by applying them to Pokemon with low catch rates to improve efficiency. Save reward items from earlier stages for requirements in later stages.
Common Pitfalls to Avoid
Don’t wait until the final day to start candy-earning tasks. Avoid using all your berries before reaching stages requiring specific amounts. Don’t overlook the local time deadline – it’s easy to miscalculate when the event actually ends in your timezone. Remember that buddy souvenirs are random, so start early to allow multiple opportunities.
Beyond these timed research tasks, Sustainability Week offers additional content including special wild spawns, raid opportunities, and exclusive avatar items. Maximize your event participation by exploring all available activities while methodically completing the research stages.
