In response to the 2018 Policy Address, Clean Air Network would like to make the following statements.
Transport demand management and vehicle emission
1.Phase out Euro IV diesel commercial vehicles by the end of 2023
CAN welcomes the captioned plan to phase out all Euro IV diesel commercial vehicles (DCV), which accounts for 23% of total DCV, by the end of 2023. Replacing all Euro IV DCV with Euro VI DCV would make significant improvement to roadside air quality. CAN urges the government to set up a timeline for electrification of commercial vehicles in HK. Full electrification should be achieved no later than 2040, with reference to London’s timeline.
2. Electronic Road Pricing(ERP) Pilot Scheme details announced in the 1st half of 2019
CAN believes that the ERP pilot scheme can effectively discourage people from driving during peak hours and improve traffic congestion and roadside pollution.CAN recommends that the polluters-pay principle should be incorporated and adopted in the scheme, meaning that vehicles that emit more pollutants should pay a higher fare.
CAN opposes government decision to increase parking lot, especially for private cars in central business district. CAN believes the decision is contradictory to the policy objective of ERP, which aims at reducing vehicular demand in central business district during peak hours.
3. Retrofitting Euro IV and Euro V franchised buses with selective catalytic convertors
Since most selective catalytic convertors cease to function in 1.5 to 2 years, CAN believes that this captioned measure would have little effect on emission reduction. CAN urges the government to fully electrify all franchised buses no later than 2036. The Chief Executive should consider to expand current low emission zone and tighten emission requirement to zero-emission buses. CAN estimates that the introduction of zero-emission buses into low emission zone would be a net reduction of 650 tonnes of nitrogen oxides per year, which roughly amounts to total emission of nitrogen oxides of all private cars in Hong Kong.
Regional Ozone and VOC control
4. Collaborating with the Guangdong Provincial and Macao SAR Governments to include volatile organic compounds (VOC) as a regular monitoring parameter in the Pearl River Delta (PRD) Regional Air Monitoring Network
CAN supports all evidence-based policy recommendations. Monitoring the emission of VOC is only the first step of tackling the current high level of ozone. We believe that the Government should establish an emission reduction target for ozone in their study on “post-2020 air pollutant emission reduction targets and concentration levels for Hong Kong and Guangdong”.
5. Mandating vessels to use low sulphur fuel within Hong Kong waters starting January 2019
To align with international trend on emission control for vessels, CAN believes that Hong Kong should take the lead in the Pearl-River Delta region and continue to push for the use of fuel with less sulphur content, from 0.5% to 0.1%, which is in line with the timeline and regulation proposed by the International Maritime Organization.
6. Pilot scheme for local ferries to ascertain the viability of green technologies in the local context
CAN welcomes the captioned scheme. CAN has long been advocating for the development of on-shore power supply in Hong Kong. Electric ferries or green ferries using on-shore power would help reduce the air pollution exposed by people commuting by water.
