Urban centres provide opportunities for a range of social and cultural activities, as well as being critical for innovations in science, technology and education. They are also of critical importance for social and economic development. However, with approximately 40% of global energy use taking place within city buildings, this sector is also the single largest contributor to global greenhouse gas emissions.
As a result, the design and use of energy and resource-efficient buildings has a key role in climate change mitigation to accelerate the global green economy transition. Although vast savings are possible by constructing new green buildings and retrofitting existing buildings, even greater gains can be achieved by adopting a long-term life-cycle approach involving stakeholders at different stages – from environmentally-minded investors and architects, to sustainable extraction, construction and usage, and the eventual demolition and the recycling or disposal of the building materials.
Cities are well-placed to play a major role in decoupling economic development from resource use and environmental impacts, while finding a better balance between social, environmental and economic objectives. Resource-efficient cities combine greater productivity and innovation with lower costs and reduced environmental impacts, offering at the same time financial savings and increased sustainability.

Urban Farming: city allotments could be as productive as conventional farms, research finds.
A two-year pilot study found that volunteer urban growers were able to harvest 1kg of insect-pollinated fruit and vegetables per sq metre in a season – which researchers said put their yields within the range of conventional farms.
“In a world of increasing urbanisation in both the developing and developed worlds, producing food in and around cities has the potential to improve both nutritional and health outcomes, alleviate poverty and simultaneously provide habitat for wildlife and create sustainable cities.”

Air pollution, congested streets, higher rates of road accidents, and carbon emissions are some of the common challenges cities face. Fortunately, cities are taking strides to change this situation.
This blog post by ICLEI presents some of the steps cities are taking for developing healthier and climate-neutral cities through sustainable urban mobility.
