The Carbon Neutral Cities Alliance (CNCA) is a collaboration of leading global cities working to cut greenhouse gas emissions by 80-100% by 2050 or sooner.the most aggressive GHG reduction targets undertaken anywhere by any city.(but this is part of the Carbon Neutrality Coalition) 1 The following 32 cities have also pledged to become emissions neutral by 2050: Austin, Accra, Barcelona, Berlin, Boston, Buenos Aires, Cape Town, Caracas, Copenhagen, Durban, London, Los Angeles, Melbourne, Mexico City, Milan, New York City, Oslo, Paris, Philadelphia, Portland, Quito, Rio de Janeiro, Salvador, San Francisco, Santiago, Seattle, Stockholm, Sydney, Toronto, Vancouver, Washington and Yokohama. The following countries pledged to become emissions neutral by 2050: Canada, CostaRica,Colombia,Denmark,Ethiopia,France,Finland,Germany,Iceland,Luxembourg,Marshall Island,Mexico,Netherlands,New Zeland,Norway,Portugal,Spain,Sweden, UK.However, current infrastructure spending in urban areas stands at USD 2.5-3 trillion per year, which is just half of the need.
