Environmental Concerns
Taxicabs have been both criticized for creating pollution and also hailed as an environmentally responsible alternative to private car use.
The results, published in the journal Atmospheric Environment in January 2006, showed that the level of pollution that people are exposed to differs according to the mode of transport that they use. The most risky method of transport was the back seat of a taxicab, followed by travelling by bus, cycling, walking, with a private car exposing people to the lowest amount of pollution.

Famous quotes containing the word concerns:
“Mr. Christian, it is about time for many people to begin to come to the White House to discuss different phases of the coal strike. When anybody comes, if his special problem concerns the state, refer him to the governor of Pennsylvania. If his problem has a national phase, refer him to the United States Coal Commission. In no event bring him to me.”
—Calvin Coolidge (1872–1933)
