THE chief executive of homegrown fintech M-DAQ Richard Koh is a longtime car aficionado. But his choice of ride has changed markedly in recent years. Over the last two years, the 49-year-old has switched his luxury gas-guzzlers - the likes of Porsche 911 Carrera 4S and Ferrari California T - for climate-friendly electric cars.

His family currently owns an MG electric sports utility vehicle and the first BMW iX3 to ply Singapore roads.

This switch comes about eight years after he decided to power his semi-detached home entirely via solar energy, a move for the environment which his family and his neighbours - after he successfully persuaded them to follow suit - have also reaped the benefits of.
