Drivers of taxis (vans, sedans and three-wheelers) powered by compressed natural gas (CNG) and operating under license to the Bangkok Mass Transit Authority (BMTA) in the Greater Bangkok region of Thailand will soon be able to take advantage of a new natural gas vehicle (NGV) credit card program launched by Prime Minister Yingluck Shinawatra, reports ThaiPR. The program is intended to help approved drivers cope with rising CNG prices in the nation until end of 2012; each card has a credit limit of BHT 3000 (USD 95) to be used specifically for fuel purchases. Cardholders are also entitled to discounts of between 50 satang and two baht on the retail price of CNG for each kilogramme paid for with the credit card. The discounts must not exceed a CNG purchase value of 9,000 baht per month (USD 287).
