As part of the 5th annual Call for Code Global Challenge, We called 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. 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.
