A vehicle 2 is operable in a first emissions mode and a second emissions mode in which at least one emission is reduced for a given drive power. The vehicle 2 is arranged to switch to the second emissions mode automatically upon determining that a current location of the vehicle 2 is within a designated reduced-emission zone. In addition to receiving and storing zone data, the vehicle may use its own sensor 4 to detect exterior air quality. Data from the sensor 4 may be transmitted to an external server 22. The invention may reduce reliance on a driver being ecologically aware. A method of designating reduced emission zones is also provided. This includes receiving air quality data from a plurality of vehicles (2 & 24-30 see fig 2).
