The Environmental Protection Department has so far not set a date to ban polluting old engines. [1]

One solution to tackle the air pollution problem is to implement the existing rail-led transport policy by giving priority to expanding the rail/underground systems rather than continuing to give priority to building roads. [2]

Another solution to the air pollution problem is to subsidize the 40,000 pre-Euro diesel vehicles to be replaced with new ones since the maximum emissions benefit can best be reaped by combining cleaner engines with cleaner ultra low sulphur diesel. [2]

There should be mandatory requirements for all diesel vehicles to move to Euro IV and Euro V standards. [3] Setting a date for all roadworthy vehicles to meet minimum emissions standards (Euro IV is proposed), then mapping a progression to higher standards, and the retirement of all buses beyond 18 years from the date of manufacture should be required. [4]

There should be introduced public finance initiatives (as with the United Kingdom’s adoption of the Public Finance Initiative model), and the creation of a legal and regulatory framework to assist both the Hong Kong Government and the bus operators in financing the acquisition of cleaner and environmentally friendlier bus fleets. [4]

After the next upgrade to Euro IV engine classes, the Government should be exploring the next upgrade that could take place within a decade, where there will be even cleaner fuel source options available, such as natural gas, hybrid and electric buses. [4]

The Bus Franchise Agreements should be reviewed to include environmental performance standards and the Certificate of Roadworthiness should be amended to more stringent limit emission levels. [4]

Stricter regulation on the qualification of technicians and the appropriateness of equipment used and so on should be enforced for the registration of garages. [5]

A vehicle related emissions data collection and management system which includes mechanics’ licensing and garage registration schemes should be developed. Data could be analyzed to produce a profile of the emissions created by the various types of vehicle so as to flag-up inadequately maintained vehicles. [5]

Controls on the quality of maintenance need to be applied across all vehicles, including commercial vehicles. Replacement of old commercial vehicles should be done as quickly as possible. [5]

Vehicle manufacturers should be required to make all repair manuals openly available so that small and medium sized repairers can achieve a better level of quality when servicing or repairing vehicles. [5]
