In its fifth year, the Call for Code Global Challenge called upon developers and innovators worldwide to channel open innovation in crafting technology solutions that confront urgent global sustainability challenges in bold, tangible ways. The need for impactful action, as emphasized in the United Nations’ 2022 climate report, has never been more pressing to avoid the gravest consequences of climate change. These solutions must reach all communities, particularly those historically marginalized and disproportionately affected by environmental harm. Technology, with its unparalleled potential for scalable, transformative solutions, stands at the forefront of the global fight for sustainability.
