AI4Cities challenges suppliers to come up with AI solutions that reduce CO2 emissions in the energy field. Energy – crucial for cities’ infrastructure, heating, cooling, security and light – is the biggest polluting source, accounting for 58% of GHG emissions in Europe's urban areas. In this context, AI technologies can be issued for storage needs, more efficient energy uses and the integration of renewable sources. Furthermore AI can help citizens to better understand how their energy consumption impacts their carbon footprint and give them tools that can facilitate the change.



The purpose of these sub-challenges is to describe and give examples of the cities’ current needs. It is not expected that a solution will cover every issue mentioned under a sub-challenge. On the other hand, solving only one of the issues listed may not be enough for the solution to advance to the later phases of the PCP. Tenderers are encouraged to address several problem areas mentioned under one or multiple subchallenges.
