The climate emergency and population growth are challenging water security and sustainable urban design in cities worldwide. Sustainable urban development is crucial to minimise pressures on the natural environment and on existing urban infrastructure systems, including water, energy, and land. These pressures are particularly evident in London, which is considered highly vulnerable to water shortages and floods and where there has been a historical shortage of housing. However, the impacts of urban growth on environmental management and protection are complex and difficult to evaluate.
Contributing to SDGs 9, 12 and 13, this paper provides an in-depth analysis of the technologies available to reduce CO2 emissions in those sectors, and the implications for introducing consistent measures to deliver on emission reduction targets.
