We analyzed the atmospheric carbon dioxide (CO2) concentration in streets of different traffic levels and urban parks of different sizes in Rome. Rome represents an example of a mega‐city, where the urbanization process has been increasing over the last years, and many new sub‐urban areas have been built by scaling down free areas surrounding the city. CO2 concentration in Rome has been significantly increasing from 1995 to date due to the increase of private means of transportation. Our results underline that CO2 concentration in streets located in the city centre has a strong diurnal trend peaking in the first hours of the morning when the traffic is the highest, then decreasing at 3:00 p.m. and increasing again at 8:00 p.m., in relation to traffic level variations. It is attested also by the correlation between the two variables. The results underline the effect of buildings delimiting the urban streets on the CO2 concentration.
