Global Challenge

What is the 2022 Call for Code Global Challenge?

Each year the Call for Code Global Challenge inspires developers and problem solvers to identify technical solutions to societal and humanitarian problems and build the solution, with the goal of deploying the solution to make a demonstrable difference.  

The winner of the Call for Code Global Challenge receives $200,000 USD and support from an ecosystem including Founding Partner IBM, Call for Code sponsors and supporters, government entities, non-profit organizations, and technology partners like the Linux Foundation. Support is provided to help set up the winning team, from concept to deployment, with guidance to bring their solution under the governance of the Linux Foundation.  

How did we determine the 2022 Call for Code Challenge theme?

Sustainability is a top priority for communities and companies around the world. But innovative solutions are needed to meet the sustainable development goals set forth by the United Nations. At its core, sustainability is a social and environmental justice issue. 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.

A Challenge Accelerator is a generally a 2-week competition that is designed to help fast-track your project towards submission to the Global Challenge, although Global Challenge submission is not required. Participants will build a project to address a specific and targeted use case​ under the theme of Sustainability. The event may include technical workshops, mentoring, and additional learning content. Participants may be eligible for additional prizes.
