AI and Sustainability:

Friend or Foe?

This is not a gardening club.

Five years in, GreenHack 2026 is still where humanity teams up with AI to tackle sustainability’s end-bosses: climate chaos, waste, reckless production, disappearing resources. We experiment, prototype, and stress-test ideas that actually help. AI isn’t the hero — it’s the sidekick we’ve all been waiting for.

AI can be at the core of what you build but sustainability leads the way. We use AI to reduce waste, save resources, and create real environmental impact, not to fuel overconsumption. At GreenHack, technology serves the planet, not the other way around.

We invite students, designers, engineers, and tech-savvy creators to join the challenge. Register as an individual or form a team of 2–4 members — bring your skills, curiosity, and a willingness to build something that matters.

Challenges (in preparation)

Grid Pulse

Energy systems are becoming more dynamic, decentralized, and weather‑driven than ever before. As renewables grow and uncertainty increases, operators need new ways to see, understand, and anticipate what’s happening across the grid. Build an AI‑powered, visually strong map‑based view of the power grid that turns complex data into clear insight — helping humans stay in control of a rapidly changing energy system.

2. Supply Chain Decoder

Scope-3 emissions shouldn’t be a mystery. Create AI tools that estimate missing data, flag dirty suppliers, compare greener alternatives, or simulate climate impact. Turn messy supply chains into transparent, actionable insights.

3. City Resource Brain

Cities waste energy, water, and time — often because they can’t see what’s happening. Build AI for smart waste routing, leak detection, recycling insight, or district energy balancing. Help cities go from reactive to intelligent.
