Towards a “zero emission transport” through low-carbon technologies(Ongoing)
KMB is investing in low-carbon technologies to reduce its carbon footprint. Initiatives such as bus shelters equipped with solar panels or the introduction of electric buses (“eBus”) and supercapacitor-powered buses (“gBus”) are paving the way for the development of electric transportation in Hong Kong. In 2021, KMB purchased more electric buses for their operations and kick-started the introduction of its first electric double-decker bus.
KMB is introducing the “ebus,” powered by lithium iron phosphate batteries, offering 200km of zero-emission transport. The “gbus,” or an electric bus model with ‘supercapacitor technologies,’ is also being introduced.
Since 2017, KMB has been installing solar power systems on its double-deckers and bus shelters (BEC, 2020). This solar power system reduces the air temperature in the bus compartment by around 8 to 10°C, leading to 3% savings in fuel consumption. KMB introduced and deployed its first batch of new buses with built-in solar panels in 2019. To fully capitalise on the potential for renewable energy, KMB is further exploring a new generation of double-deckers equipped with more solar panels.
KMB has also reduced its fleet’s proportion of Sulphur Diesel usage to 0.001%. Finally, KMB is also recycling retired buses. As of 2020, 34 buses have been donated to schools and reconverted into educational spaces.
Diesel vehicles, such as buses, are one of the largest sources of street-level pollution
In 2020, the total direct and indirect GHG emissions (Scope I and Scope II) of KMB and LWB was around 520,000 tonnes of CO2e
