This GSMA ClimateTech report explores the use of mobile and digital technologies across start-ups in low- and middle-income countries (LMICs) that applied to the GSMA Innovation Fund for Climate Resilience and Adaptation. The report also presents the climate tech innovations being used by the 12 start-up organisations in Asia and Africa selected under GSMA’s climate grant funding round. The report showcases how technologies such as the Internet of Things (IoT) and blockchain can be used creatively to help communities anticipate and adapt to climate shocks and stressors.
