At the COP23 Climate negotiations in Bonn, C40 and McKinsey, published a new report, ‘Focussed Acceleration’, which will enable mayors to assess the ambition of their own climate plans against the modelled analysis produced by McKinsey and Arup. The analysis showed that if resources were concentrated on a small number of key policies and actions across the majority of cities, then C40 members can demonstrate that it is possible to cut emissions in line with the Paris Climate Agreement targets.
The majority of the energy used by buildings is wasted, resulting in increased energy costs and air pollution. Among C40 cities, this translates to between 50 percent and 75 percent of citywide carbon emissions. Therefore, due to the sheer amount of energy consumed by buildings, urban decision-makers have an opportunity to make an outsized impact by targeting municipal building efficiency.
The successful cities of the future will achieve greater mobility and zero pollution, through innovative, shared transportation models and strong networks. This is the vision of the partnership between C40 Cities and Mastercard.
In November 2017, C40 FSCI hosted a five-day Study Tour for city officials from C40 cities with ambitions to electrify their municipal bus fleets. Delegates from Auckland, Buenos Aires, Durban, Los Angeles, Quito, Santiago and Tshwane took part in a number of workshop sessions and site visits as they travelled through Warsaw, Brussels, Namur, Paris and Barcelona to learn best practices first-hand from pioneering electric bus operations in Europe.
‘Liveable Streets’ is a seminal 1981 work by the urban designer and theorist Donald Appleyard that compared the experiences of people living on three similar streets in San Francisco. The main variable between the streets was different levels of car traffic: one with 2,000 vehicles per day, one with 8,700 vehicles per day and a third with 15,750 vehicles per day. Appleyard’s key finding was that residents of the high traffic streets were less likely to know their neighbours and more likely to feel lonely and isolated from their community. The evidence of the negative physical, mental and social effects caused by living near busy roads has only grown in the subsequent years. By Mark Watts, C40 Executive Director
