Greatly reducing the pollution of Hong Kong's roadside air is as easy as replacing the fleet of ageing diesel buses with electric ones. The solution is as near as Shenzhen, where a leading producer of such vehicles, BYD, is based.
BYD Co makes rechargeable batteries and cars in Shenzhen in Guangdong province. Founded in February 1995, and listed in Hong Kong in 2002, the origin of the company’s name is uncertain, with some saying it could simply be an acronym based on its Chinese name or from the phrase “build your dreams”. BYD’s profile was raised in 2008 when a unit of billionaire Warren Buffett’s Berkshire Hathaway invested about US$230 million in BYD.
