Hong Kong has launched a trial run of a fleet of electric taxis in a bid to tackle the island's serious pollution problems which, according to estimates from the independent think tank Civic Exchange, cause 3,200 premature deaths per year.

For the next six months, 45 low emission taxis will be trialled after a similar test in nearby Shenzen city proved successful.
