How did we determine the 2023 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. To do the most good, sustainability solutions should have global potential, but they also need to benefit local communities, especially marginalized communities that are most often polluted or left out of policymaking. Technology is key, as open innovation can address sustainability challenges effectively and at scale.
