The Green Route (Deloitte Spark Hackathon)

1) Background

Most navigation apps optimize for time and traffic, while environmental impact stays invisible or buried in secondary views. The hackathon challenge (with Deloitte, WWF, and AI Sweden) asked teams to make the planet’s “vital signs” visible and actionable through a digital product.

2) Problem

• Users can’t compare routes by environmental impact at the decision moment.

• Existing “eco” features are too abstract (CO₂ numbers only), creating weak motivation.

• People assume eco-friendly choices require major time trade-offs.

3) Goal

Embed an “environmental intelligence layer” into route planning so users can choose routes that balance speed and environmental impact, and take small actions that feel achievable.

4) My Role

UX/UI Designer + user insight lead:

• Defined user needs and behavior-change strategy

• Designed key flows + interaction model for route choice

• Built the high-fidelity interactive prototype (Figma Make)

• Translated complex environmental data into glanceable UI

5) Solution (What We Built)

• 3 route options with clear trade-offs: Fastest / Eco-Balanced (recommended) / Planet Hero

• A 0–100% environmental impact score to make comparison simple

• Contextual “micro-actions” (e.g., plant a tree for this trip; slow down in wildlife zones)

• End-to-end flow: route planning → in-ride guidance → trip summary → personal impact view

6) Outcome

• Delivered an interactive hi-fi prototype covering 5 core screens.

• Estimated impact: ~120,000 tons CO₂ reduction/year if 5% of users choose the eco-route.

• Team won 3rd place at the Deloitte Spark Hackathon.
