According to a study by the climate leadership group C40 Cities, Greenhouse gas emissions from urban consumption must be reduced by 50% by 2030 and 80% by 2050 to avoid a “catastrophic” climate crisis.
This prestigious organization brings together 94 of the largest cities on the planet, which bring together more than 700 million inhabitants and a quarter of the world economy. According to the conclusion reached after the large-scale analysis carried out together with the consultancy Arup and the British University of Leeds, the reduction in urban gas emissions is essential to maintain the possibility that the increase in temperature at the end of century does not exceed 1.5 degrees.
The main sectors of the planet that must make the effort are: Europe, the United States and East Asia, which are asked to reduce the climate impact of their consumption by two thirds in the next decade, where changes in diet are imposed, construction, clothing, transportation and electronics. While Latin America, Africa and South and West Asia have the challenge of adopting sustainable models in their development.
The study analyzes that emissions related to food should fall by a third by 2030 with a diet based on plants, healthy amounts, avoiding waste by large quantities. For example, a person's annual meat consumption could be reduced from the current 58 kilos to 16.
Regarding emissions resulting from construction, it is concluded that they will fall by 26% by 2030, with incentives to reduce the use of steel and cement or make the most of the capacity of buildings.
The analysis also sees it necessary to cut emissions linked to private road transport by 28%, or 26% in aviation, on which it indicates that "there should be an average reduction of 28% in the number of flights between cities of the C40" .
According to the conclusions, they estimate that reducing flights and using sustainable fuel could avoid 70 million dollars (62 million euros) in damages derived from air pollution. And eating less red meat and more fruits and vegetables could prevent 160,000 annual deaths linked to heart attacks, cancer or diabetes.
Among the cities that belong to this network chaired by the Parisian Anne Hidalgo, there are also Madrid, Barcelona, Beijing, Hong Kong, Shanghai, Tokyo, Seoul, Berlin, London, Istanbul, Rome, Mexico City, Buenos Aires, Bogotá, Rio de Janeiro, Lima, Santiago de Chile, New York, Los Angeles or Washington.
