Push for a better, cleaner diesel for cars in Bangkok

At long, long last the junta is considering action to reduce Bangkok’s hazardous air pollution. Instead of running around like a headless chicken, Prime Minister Prayut Chan-o-cha should consider that the Pollution Control Department (PCD) has found that 52 per cent of PM2.5 pollutants come from diesel-powered vehicles – and focus the counter-measures accordingly. This would follow Stephen Covey’s “7 Habits of Highly Effective People”, one of which is, “Begin with the end [goal] in mind.”
The PCD conclusion has been vividly demonstrated by the police, who reportedly issued 10,000 tickets in a single day just 20 checkpoints set up to measure diesel exhausts.
Perhaps more should be done, like tripling the number of police checkpoints, running them 24/7, checking buses at night, and conducting checks on trucks as they line up on the outskirts waiting to enter the capital at 9am. 
Form flying squads of deputised soldiers, under direct control of a police officer authorised to issue tickets, check trains at terminals, and promote the use of B20 bio-diesel and Euro 5 fuel. I understand that we can go all the way up to B100 without damaging engines – why hasn’t this been done yet? If going to B40 or higher is in the national interest, we should use the Oil Fund to cushion losses to oil refineries while they adjust over, say, a three-year period.
Prayut, focus on attacking the root cause of our pollution instead of PR stunts like reducing operating hours for factories, reducing the number of petrol-powered cars or banning diesel trucks even if they meet emission standards.
