The most lethal thing you can breathe in at road level is particulate matter (PM) 2.5 emitted from the exhausts of old diesel vehicles, which exacerbates the PM2.5 in the air from our power companies.
Diesel emissions also contribute to our urban smog. The government has offered generous terms for the owners to trade up to newer Euro V vehicles.
This offer is akin to asking smokers to stop smoking.
The government needs to be more proactive and force these old diesel trucks and buses off our roads.
It would be interesting to know how many vehicles the bus companies here actually own rather than lease from the banks. Voluntary measures will not work so more stringent methods such as increased licensing costs need to be used.
