The LIFE IP HUNGAIRY project and within it the "Life1" mobile application was created with the support of the LIFE IP HUNGAIRY (LIFE17 IPE/HU/000017) project of the European Union's LIFE program. The aim of the project is to improve air quality in 8 regions and 10 Hungarian settlements by promoting the implementation of air quality plans. The application can be used to query and monitor the amount of heat consumption and CO2 savings in the given place of use during the requested period.
