New transport scenarios highlight role of cities

On 4 December the International Transport Forum at OECD released projections for modal shares, and emissions at the Lima COP20 conference.

Transport in the urban centres of emerging economies is becoming a major battleground for combatting climate change. Large cities in China, India and Latin America each with over 500,000 inhabitants will more than double their share of world passenger transport emissions by 2050 to 20% (2010: 9%), if current urban transport policies remain unchanged. It is understood that 38% of the total growth in world surface transport passenger emissions to 2050 will come from big cities in these three regions in such a business-as-usual scenario.
