Transport in the urban centres of emerging economies is becoming a major battleground for combatting climate change. Big cities in China, India and Latin America 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. 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. These new projections, released today by the International Transport Forum (ITF) at the OECD during the COP20 climate change negotiations in Lima, Peru, highlight a critical choice for policy makers: whether to pursue urbanisation based on public transport or on private transport with cars and two-wheelers.
