The HK$10 billion announced in Chief Executive Leung Chun-ying's policy address to "remove tens of thousands of the dirtiest vehicles from the streets" will be wasted. This measure probably came about thanks to lobbying by vested interests from the motor trade.

I do not believe that the administration of Chief Executive Leung Chun-ying can deliver clean air to Hong Kong.

The HK$10 billion announced in his policy address to "remove tens of thousands of the dirtiest vehicles from the streets" ("Full speed ahead on old trucks' road to the scrapyard", January 17) will be wasted. This measure probably came about thanks to lobbying by vested interests from the motor trade.

The objective of this HK$10 billion fund is to help buses and trucks make the transition from badly polluting exhaust emissions to Euro V standards. According to government data, that means a reduction in two main areas, nitrogen oxide and particulates, the latter includes the infamous PM2.5 pollutant.

In all vehicles, including Euro V, this can be done using a catalytic converter. Generally, these devices cost a few thousand dollars. So, why do we need to scrap our old dirty vehicles, when all that needs to be done is for them to be fitted with catalytic converters?

It would be better to use some of the HK$10 billion in this way. Make these devices mandatory for all dirty vehicles and ensure they are regularly checked and maintained. Whatever is left over could be used to install "air cleaning stations" as we have severe roadside pollution. Local universities are doing research on these stations, which are filtering devices, with air passing through and being cleaned.

The air filtering system can handle huge volumes of air quickly, using water vapor- isation and ionisation to take out pollutants.
