One of the clearly outlined directions of the ETA2U Foundation is the promotion of a healthy environment. In this aspect, Romania is not doing well because its urban environments are the most populated in Europe. We believe that by using technology in an innovative way, this situation can be improved. Thus, the aim of the "Green Code for Bucharest" project is to implement a technical infrastructure that aims to record air quality data in Bucharest in real time. Within the same project will be carried out 4 campaigns for information, awareness and education of the population. Project developed in partnership with the IKEA Fund, Bucharest Community Foundation and the Ecopolis Association and will last 18 months.
