Energy transition acceleration towards climate neutrality powered by AWS

Their software suite gaia provides tooling and insights to energy suppliers and grid operators, cities and entire regions as well as planning and consulting companies that are involved in energy transition.

gaia’s core is a digital twin of the real world, containing data and visualizations of the CO2 emissions of individual buildings, energy plants and other infrastructure. It allows for status quo analysis and reporting according to national standards in various countries, and has integrated project management capabilities to coordinate time, costs and stakeholders of the actions taken on the path to climate neutrality.
