In what appears to be a short reprieve for Mumbai's transporters, the Bombay high court granted a three-month extension to the phase-out deadline of December 31, 2002. About 20000 diesel-run transport vehicles, which include trucks, buses and vans older than 15 years, now have time till March 31, 2003, to either convert to run on Compressed Natural Gas (CNG) or be scrapped.
