About this app

SustainWise — master the language of sustainability.

If you've ever nodded along in a meeting while someone said "double materiality" or "Scope 3" and hoped nobody would ask you to explain it, this app is for you.

SustainWise is a Duolingo-style learning app that turns ESG and sustainability jargon — CSRD, CSDDD, SFDR, the EU Taxonomy, GRI, and much more — into short daily lessons you can actually stick with.

COMPLETELY FREE
No subscriptions, no paywalls, no ads. Every module is free to learn.

Your streak, XP and progress are stored on your device — there's no account to create and nothing to sign up for.

WHO IT'S FOR
• Sustainability professionals who want the vocabulary to match their expertise
• Compliance, finance and legal teams who keep running into ESG terms they half-know
• Anyone who's ESG-curious and wants to actually understand the headlines

HOW IT WORKS
• Flashcards — flip a term to reveal its real definition, then rate yourself so the app knows what to reinforce
• Quiz — multiple-choice questions built from real definitions, with an explanation every time, right or wrong
• Confusable Pairs — a harder round for the acronyms and concepts people mix up most (CSRD vs. NFRD, GRI vs. ESRS, and more)
• Streaks, XP & levels — daily practice that actually builds a habit, with your progress saved on your device
• Daily goal & achievements — a real reason to open the app today, judged only against your own progress
• A real learning path — modules unlock as you go, grouped into units from foundational ESG concepts through EU reporting law, sustainable finance, climate accounting, governance, and more
• Expert Challenge — 25 genuinely hard questions on thresholds, edge cases and the fine print, unlocked once you've completed the full curriculum

WHAT'S INSIDE
Real, curated content — not generic AI summaries — covering CSRD & ESRS, CSDDD, SFDR, the EU Taxonomy, GRI Standards, TCFD/TNFD/SASB/ISSB, sustainable and ethical investing, climate & carbon accounting, circular economy & biodiversity, human rights & social issues, governance & anti-corruption, greenwashing regulation, and the key institutions and milestones behind it all.
Learn ESG, CSRD, ESRS and sustainability terms with quick daily quizzes.
