One of the most pressing issues facing cities and urban spaces are the future impacts of climate change, and how to make critical decisions related to mitigation and response. This month, ITU's AI for Good Innovation Factory series kicked-off with a challenge on smart and sustainable cities. Sipremo, a Brazilian-based start-up applying artificial intelligence (AI) for smart decision making, was awarded the top prize for start-ups making our cities safe, clean and sustainable. We talked to Gabriel Savio, CEO of Sipremo, about his solution. Sipremo addresses the massive impact of climate change events on business in various industries and all of our society. In recent years, Brazil has faced some of its worst natural disasters, such as what happened in Petropolis, Minas Gerais, and others.
