What are the benefits of using EVs?

EVs are more energy-efficient than cars using conventional internal combustion engines. Based on the current electricity generation fuel mix, EVs emit less carbon emissions on average than their conventional counterparts (tank-to-wheel) on the same mileage travelled. With zero roadside air pollutant emissions, EVs also help improve the roadside air quality in the city.

What is "EV-charging at Home Subsidy Scheme" (the "EHSS") launched by the HKSAR Government?

The HKSAR Government rolled out a $2 billion "EV-charging at Home Subsidy Scheme" (the "EHSS") to subsidise the installation of EV charging-enabling infrastructure in car parks of existing private residential buildings, and hence further facilitate EV owners to install EV chargers at car parks of their residences according to their own needs in the future in a simple and easy manner. The EHSS will run for about 3 years with a view to covering roughly 60,000 private parking spaces. Processing of applications is on a first-come-first-served basis until the funding is used up.
