"Effective urban transit systems can encourage people out of their cars and provide a cost-effective way to tackle climate change, a report has suggested.

It calculated that emissions from urban transportation could be cut by more than half by 2050 and economies save in excess of US $100 trillion. The authors added it would also reduce annual premature deaths by 1.4 million. The report is being published at a UN Habitat III meeting ahead of Ban Ki-Moon's climate summit next week. The findings were published in a study by researchers from the University of California, Davis, and the Institute for Transportation and Development Policy (ITDP). (...)

The report offers a vision of how this might be achieved in it's "high shift scenario", in which it envisages a far greater proportion of urban passenger travel via "clean public transport" and non-motorised means, such as cycling and walking.

Urban transit systems, such as trams, can help cut congestion and improve local air quality. It also includes a decrease in the rates of road construction, parking garages and other means that the authors consider to encourage car ownership.
The report also states that, without changes in policies and investments, rapid urbanisation will result in emissions from urban transportation almost doubling from 2010 levels by 2050. "The traffic congestion we see today will become much greater and will result in many more hours being stuck in traffic," Mr Replogle said, adding that congestion would also have a detrimental impact on nations' economic activity, as people would be late getting to work or meetings.
