Straits Times Forum 16 Feb 09;
I REFER to last Thursday's commentary, 'Do CNG cars have a future?'
I assume that the question of compressed natural gas (CNG) cars being 'viable' relates mainly to their economic feasibility. This is understandable, especially with the recession in full swing. However, does that mean we should 'forget' about our moral obligations to Mother Earth until our economic woes are resolved? I hope not. In fact, there is no better time than now.
The most sensible option is to intermesh economics and the environment together (where they belong): Incorporate environmental benefits from greener vehicles - or costs from polluting vehicles - into the economic costs that consumers bear.
Thus, I see no reason for the current 40 per cent green vehicle tax cut to be discontinued from 2012. Drivers brave enough to make the transition should be rewarded. Nevertheless, to be fair, if taxation is chosen, payments should be re-channelled into green investments or research.
Another important move would be to make CNG or liquefied petroleum gas pumps more accessible. Having a few at regular petrol stations would spare would-be users inconvenience and snaking queues. With other countries allowing drivers to refill at home (as the gas is used for cooking too), we still have a long way to go.
On a similar issue, I find it puzzling why cars have to run on petrol when diesel is a more environmentally friendly option, emitting less carbon dioxide and most other pollutants, as well as being cheaper.
Although diesel was once more polluting, current technologies are far better than the '20-year-old engines' in many vehicles. Is it then not time to upgrade these engines, and give drivers a choice?
Ideally, reduction in demand should be the way. Even in the current situation, perpetual traffic jams make it impossible for drivers to adopt good driving habits, as idling cars generate greenhouse gases. It is ironic that most commuters need to travel in private vehicles in a tiny, well-connected land of 707 sq km.
Fewer fossil fuel-guzzling vehicles (public transport included) would do wonders for the environment. If roads could be safer and friendlier for cyclists and pedestrians, we might see an improvement in traffic, environment and health. After all, how expensive is a pair of walking shoes?
