Cool Cities

Since the start of the industrial revolution, there were some problems associated with economic development like Rises in population, increase energy consumption, traffic delay and the emission of carbon dioxide. However, if we don’t solve these problems we will need another earth to replace our own. We suppose to decrease the amount of carbon dioxide emitted by one half to live within the capacity of a single earth. In Japan during the last 30 years GDP has gone up 100% while energy efficiency has increased 37% and oil consumption has decreased 8%. Ninety percent of carbon dioxide emitted into the air comes from the buildings and transportations. Cool City is a city which can reduce carbon dioxide emission by 60% as well as provide with enjoyable life style. SDCJ is building the Cool City and they are from Japan. There are three types of transportations which will be used in Cool City for example hybrid, water taxi and monorail. The various zones in the city are business cultural greens. Water, trees and roof membranes will be used as techniques to reduce the heat. Fifty percent and thirty percent are the expected CO2 reductions for the two types of buildings. The overall percentage is 60% of reduction of CO2 emission claimed in the video.

This blog is about Cool Cities I hope you enjoy with these articles. I hope you find it interesting.

Carbon Dioxide

Carbon dioxide (CO2) is emitted from many sources and its main reason of global warming. It is emitted naturally through the carbon cycle and through human activities like the burning of fossil fuels. Natural of CO2 occur within the carbon cycle where billions of tons of atmospheric CO2 are absorbed from the atmosphere by oceans and growing plants and are emitted back into the atmosphere through natural processes. When in balance, the total carbon dioxide emissions and removals from the entire carbon cycle are roughly equal. Since the Industrial Revolution in the 1700’s, human activities, such as the burning of oil, coal and gas, and deforestation, has increased CO2 concentrations in the atmosphere. In 2005, global atmospheric concentrations of CO2 were increased higher than they were before the Industrial Revolution. Global temperatures are expected to continue to rise because CO2 is increasing as human activities continue to add carbon dioxide. As a result this will lead to make serious environment problem such as earthquakes, flooding water, and climate change.
