Introduction: A Green Economy for Green Cities
With the international sustainable development discussions exploring the concept and new driver “Green Economy within the context of poverty eradication and sustainable development”, it is important and relevant to reflect upon its meaning for cities and urban areas. Cities and urban areas are a key dimension as by 2050 two-thirds of all humans will be living there. They represent 2 % of the Earth’s land surface, 50 % of the global population, and 70–80 % of the global energy consumption and CO2 emissions. At the same time there is a backlog in providing decent housing and infrastructure to one billion urban dwellers, while the global urban population will increase by another three billion over the next 40 years: a near doubling of the urban population to 6.2 billion.
