Effects of low temperature on the cold start gaseous emissions from light duty vehicles fuelled by ethanol-blended gasoline

► Most of the pollutants studied were emitted during the cold start of the vehicle. ► More carbonyls were associated with oxygenated fuel (E85-E75) than with E5. ► Acetaldehyde emissions were found particularly enhanced at −7 °C with E75. ► Elevated methane and ozone precursor emissions were measured at −7 °C with E75. ► Ammonia and toluene emissions associated to E75-E85 were lower than with E5.
