he UN Information Center to Tehran (UNIC) published the UN chief message on the occasion in a press release on Sunday.
The full text of his message reads:
“For more than half a century, most countries have experienced rapid urban growth and increased use of motor vehicles. This has led to urban sprawl and even higher demand for motorized travel, with a range of environmental, social and economic consequences.
“Urban transport is a major source of greenhouse gas emissions and a cause of ill-health due to air and noise pollution. The traffic congestion created by unsustainable transportation systems is responsible for significant economic and productivity costs for commuters and goods transporters.
