2022 Call for Code Global Challenge

Build tech solutions for a greener future

Submission deadline: October 31, 2022

Build skills, save the planet

Through the 2022 Call for Code Global Challenge you can learn about AI, cloud development and emerging technologies while you make a difference. Form a team and take on sustainability issues from improving supply chains to clean energy solutions and protection of biodiversity.

About the Global Challenge

How can technology improve sustainable production, consumption, and management of resources, reduce pollution creation, and protect biodiversity to create a greener future?

As part of the 5th annual Call for Code Global Challenge, design and build an open source solution in the cloud to take on a sustainability issue. We're calling on teams of developers and problem solvers to leverage open innovation and develop technology solutions that address specific global sustainability problems in unique, clearly demonstrable ways. The top Global Challenge solution receives implementation support from IBM and the Call for Code ecosystem to make a real impact in the communities with the greatest need.

As the United Nations recently emphasized in their 2022 climate report, impactful sustainability actions are needed now to curb the worst consequences of climate change. Sustainability practices and solutions need to benefit all communities, but especially those communities that have been marginalized and polluted in the past. Technology is key, as it can provide effective, scalable solutions to address sustainability challenges. By participating in the Global Challenge, in addition to the chance to win prizes and implementation support, you’ll build critical skills for yourself and your team and contribute to projects that have the potential to help our planet.

Your Global Challenge solution should address one of the diverse challenges aligned to sustainability: 

  • Build effective and efficient ways to quantifiably promote, preserve, and protect biodiversity
  • Reduce global food insecurity through, as examples, improvements to distribution or sustainable farming practices
  • Build equitable access to sustainability solutions, education, and job opportunities
  • Improve the ability to measure, analyze, or take decisive action on carbon emissions
  • Improve access to affordable and reliable clean energy
  • Improve supply chain transparency and traceability to bring fast and accurate visibility to sustainability issues where they arise
  • Address issues of water scarcity and quality
  • Reduce volume of and demand for materials that create the biggest waste footprint (plastics, electronics, food, textile), and encourage reuse/recycle opportunities

Who should participate

There are many ways you can build a great team, but the most successful teams often bring together diverse skill sets to design unique and impactful solutions. Consider building your team to include:


The tech lead of your team. Builders bring the coding background and technical know-how to take your solution from idea to working reality.


Your UX expert who ensures the solution is user-friendly and visually appealing. Designers bring creative vision to technical problem solving, making what you build sleek and easy-to-consume.


Good communicators make complex ideas simple and inspiring. Your team's calculating hustler is essential in articulating the problem and succinctly defining how the solution can make a difference in a profound, unique, consumable way.


Altruistic thinkers who understand the complex problems at hand in a truly human way and are committed to finding a solution to make a demonstrable difference. This inspirational lead of your team considers the communities in need, while also thinking like the individual user.
