One Sky Collective is a sustainability platform that helps organizations drive employee engagement through climate action challenges. Employees use the mobile app to complete sustainability activities and track their impact.
Problem: Sustainability apps struggle with long-term user retention
Outcome: I designed a team-based challenge experience to drive engagement and helped secure a partnership reaching 60K+ potential users upon launch

I joined One Sky to help them tackle the low user retention challenge faced by sustainability platforms
One Sky's research showed that sustaining long-term engagement is a key challenge for sustainability mobile platforms and that major competitors have yet to design around the key drivers of engagement.
Since One Sky is a B2B2C business, the company’s goal was to create a solution to drive ongoing participation, structured around organizational adoption.
I started off by reviewing their existing their research to gather more insights around this problem.

Through my research synthesis, I identified 4 behavioral drivers behind long-term sustainability engagement; I then reviewed two leading corporate focused sustainability apps against these drivers
Behavioral Drivers:
People are more likely to take sustainable actions when participating with others.
Social recognition and friendly competition increase long-term engagement.
Visible impact motivates users to continue participating.
Fun and convenience are strong drivers of sustained engagement

I held a strategy workshop with the team to identify a participation model that embodied the research-driven behavioral drivers and One Sky's vision of collective sustainability.
Evaluating the strengths and trade-offs of each model, a team-based participation model emerged as the strongest because it reinforced the four behavioral drivers identified during research

During a sync with Product, I was informed one of our original flagship challenges was no longer viable as a partnership with a third-party tree-planting partner was proven to be too expensive for One Sky
Templates allow users to design their own challenges with custom goals

The original cleanup challenge already satisfied two of the flagship criteria. However, it was lacking meaningful impact measurability. I decided to improve this in order to evolve it to a flagship challenge

The team agreed that unique challenges would encourage teams to join, but customizing goals and cover images alone wasn't enough to motivate them to keep coming back.

The question became: “beyond contributing to sustainability, what does the user actually get out of completing the challenge?”
