A polluter-pays policy will not help keep the air clean in the long run
In view of the fact that we have lost the air quality gains accrued through the conversion of vehicles from diesel to CNG, a Supreme Court-appointed panel is right in asking the Delhi government to put a cap on the number of diesel vehicles in the city (Limit registration of diesel vehicles in Delhi: SC panel, November 29). Besides keeping the number of unregulated diesel-guzzling passenger cars and trucks in check, we need better and stricter implementation of emission norms. Also, we need to realise that a polluter-pays policy may work in the short run but for long-term results we need a holistic approach to improve the quality of air.

He should mind his language
This refers to Khushwant Singh's article Diwali, the past and present (With Malice Towards One and All, November 26). In a country where a large ageing population does not have the financial resources to get medical treatment, it is sad that Singh is using his column to vent his spleen about how depressed he feels. Singh has had disdain for restraint in speech and thought all his life. His columns contain words that would be embarrassing to utter in decent company. But without the shock value of such language, Singh would be just another writer.

Politics with a difference
This refers to the editorial Now, talk the talk (November 29). There's no doubt that Arvind Kejriwal's campaign has given some direction to middle-class anger. But it is time he set an agenda for his Aam Aadmi Party and reflected on its political ideology. If he does this, then Kejriwal has the potential to become a harbinger of a new class of politics that believes in development and not mudslinging.
