About the challenge

Brilliant minds coming together to solve a problem for good -  Welcome to this year’s Girls in Tech Hackathon: Hack for the environment. Organised into teams, members will work together to find the most innovative solutions to the climate’s biggest challenges.

Focusing on sustainability, climate change, and deforestation, this competition will see your project reviewed and your thinking tested, by a panel of expert judges. You’ll walk away with a project to add to your portfolio, specialized mentoring, team networking, and comprehensive exposure to a new sector of tech.

What to Build

Think about how your team might use tech, AI, blockchain and other technologies to come up with answers to the following problems.

  • Waste: Less than 9% of all plastics are recycled globally. Is there a way you and your team can come up with an idea to increase the recycling rate of plastics, whether in the USA or elsewhere?
  • Deforestation: Can you come up with a tech idea to track and disrupt deforestation? How might we track deforestation and the increasing number of trees being planted in the Amazon?
  • Endangered species: Tigers in Southeast Asia, rhinos in Africa. Animals are being poached, decreasing biodiversity. How might we use technology/AI to increase animal biodiversity?
  • Climate change: Can you think of how tech could help increase the lifespan of car batteries and assist battery-powered cars to go further? Can you think of ways renewable resources could achieve this?
