Cities and Environmental Planning

MORE

An estimated 4 billion people—equivalent to approximately 54 percent of the world’s overall population—reside in cities. The global urban population is projected to escalate to 66 percent by 2050. The UN, however, claims that the current rise in the cities' population  is unsustainable. Many cities do not have enough resources to sustain the projected population growth. Cities experience sustainability issues such as pollution, public health problems, overcrowding and social instability. These issues can lead to resource depletion and potentially low worker productivity, which can cause greater inefficiencies within cities that impact productivity.

CDP’s 2018 Climate Change Questionnaire Changes

MORE

CDP performance is one of the key indicators of a sustainable business, helping to evaluate the impact companies have on climate change. Investors and customers consider a business’ CDP performance to be a good indicator of its sustainability. CDP’s rankings measure transparency of climate change impacts, as well as the efforts taken to mitigate and reduce those negative impacts. The CDP Climate Change Questionnaire focuses on how businesses incorporate climate change risk analysis into planning, strategy, risk, and opportunities reporting. Disclosing an organization’s sustainability efforts, such as improving climate change impacts, as a part of its core business strategies can improve its CDP performance.

Sustainable energy refers to “[energy that] meets the needs of the present generations without compromising the ability of future generations to meet their own needs.”
