International delivery companies are taking the lead in cutting roadside emissions in Hong Kong and hope their local counterparts will follow suit.
FedEx Express commissioned 10 electric vehicles in Hong Kong in March, the logistics giant's first zero-emission fleet in Asia as it attempts to reduce fuel consumption by 4 per cent in the city.
The 10 electric vehicles have made the 254-strong delivery truck fleet greener.
Vehicles are the biggest source of air pollution in the city, with 67 per cent of carbon monoxide coming from road transport and 19 per cent of respirable suspended particulates emitted by cars, according to the Environmental Protection Department.
"The 10 Ford Transit vans, made by Smith Electric Vehicles, will be deployed in Chai Wan, Kennedy Town, Tsuen Wan and Sha Tin," said Anthony Leung, FedEx Express's managing director for Hong Kong and Macau.
FedEx has a fleet of 250 electric cars and 360 hybrid cars globally, which play a key role in pursuing its goal of saving more than 75 million litres of fuel every year. The company has just tightened its 2020 fuel consumption target to a 30 per cent cut from what it used in 2005.
UPS, which introduced its first hybrid-electric vehicle in Hong Kong in 2011, said it is going to add more hybrid vans later this year. Its hybrid car is 35 per cent more fuel efficient than a traditional car.
DHL Express introduced six bicycles last month that are capable of charging the hand-held mobile scanners used by DHL couriers, and it commissioned one hybrid truck in Hong Kong in 2011. Its fuel consumption is 24 per cent lower than a normal truck. The company said it is in the process of evaluating other electric vehicles.
"Being green … means [not just] changing the car but changing the driving attitude as well," said Leung. "Eco-driving includes moderate driving speeds, keeping the car temperate at 25 [degrees Celsius] and turning the engine off when waiting."
