By relating each variable to the others through a ratio, an indicator is obtained that corresponds to a coupling-decoupling category. In total, 36 indicators (by country) were analysed for the three countries. The results reveal that transport volume changes proportionately more than economic activity (materialization). Conversely, CO<sub>2</sub> emissions change proportionately less than do economic activity and surface transport volume (decarbonization), although Mexico requires greater efforts.
