By European standards, Romania is a lowurbanized country. There exists a rising trend towardssuburbanization, however, that is not fully captured byRomania’s urban statistics. The country’s urbanization rateof 55 percent has remained fairly constant over the past twodecades, despite significant population migration out of thecountry, and a strong suburbanization trend in areas on theimmediate outskirts of major cities. Because centralgovernment demographers still categorize some of theseregions outside of the urban core as rural, this shift hasnot yet made its way into the official populationstatistics. If this were to happen, the urbanization ratecould rise to 65 percent. The objective of the urban sectoranalysis was to provide insights to the Romanian Ministry ofEnvironment, Waters and Forests (MEWF) on opportunities tochange the trajectory of greenhouse gas emissions (GHG) inRomanian cities, using the Bucharest–Ilfov metropolitanregion (BIMR) as an example.
