In an effort to protect the fragile Himalayan environment of Uttaranchal and attract tourists, pollution-free buses will be introduced in major tourist towns of Uttaranchal. The Uttaranchal Transport and Technical Education Minster, Mr. Hira Singh Bisht, said that the diesel tempos "Vikram" spew a lot of smoke, and so the state government was not issuing any permit to new tempos and nor was it extending the licenses of the existing ones.
