The Supreme of India ruled on July 28, 1998 that all eight-year-old-buses and pre-1990 three-wheelers and taxis would have to be converted to CNG by March 31,2000. For the rest of the buses, three-wheelers and taxis, the deadline was fixed as March 31, 3001. This order, however, is getting to be the most difficult to implement. Resistance from the diesel lobby and lack of support from the government are out to sabotage the Supreme Court orders to move the buses, auto and taxis to CNG.

The first in the series of independent technical assessments by three CNG experts, this report provides a clear roadmap to help the government design appropriate policies, chart new action plans and re-orient strategies to implement the CNG programme in India's capital. Its release coincided with the introduction of CNG buses in the capital amidst the furore raised about their safety and performance.
