The problem

Most eco apps fail because they're preachy or boring — and they don't drive behavior change.

Gamified daily carbon tracking with challenges and friend comparisons. Think Duolingo + Strava, not a sustainability lecture.

Climate-curious Gen Z and millennials who'd rather earn a streak than read a report.

Suggested

Push notifications + camera logging push this to native. Emergent's built-in AI handles photo→carbon estimates without juggling vendor keys.

Native mobile — you wire these up once.

1
Photo-based logging
Snap a meal, grocery, or commute and AI estimates the carbon impact.
2
Levels & badges
Unlocks challenges and rewards as you stay consistent.
3
Social notifications
‘Sahas biked to work 🚴' nudges your friend group.

Photo → carbon score → daily total with a streak counter. Friends and badges come once a single user is hooked.

Campus ambassadors — sustainability clubs love a shareable streak.
Strava/Duolingo style weekly recaps that screenshot well on Instagram.
B2B angle: ESG-conscious companies buying team subscriptions for engagement programs.

Carbon estimates are fuzzy by nature — always show a range, never a fake-precise number.
Avoid moralizing copy; gamify the action, don't shame the user.
If you sell offsets, partner with verified registries (Gold Standard, Verra) — otherwise it's greenwashing.

Streak length at day 14. If the median user holds a 7-day streak, the loop is sticky enough to monetize.

ESG awareness is growing, especially with Gen Z.
