cool cities

Since the start of the industrial revolution, there have been some problems associated with economic development like: rises in population, increased energy consumption, traffic delays and increases in carbon dioxide emitted into the air. If we don’t solve these problems we will need another earth to replace our own. By one half (50%) we will have to decrease the amount of carbon dioxide emitted into the air to live within the capacity of a single earth.
In Japan during the last 30 years GDP (Gross Domestic Product) has gone up 100 percent while energy efficiency has increased 37 percent and oil consumption has decrease 8 percent. About 90 percent of carbon dioxide emitted into the air comes from building and transportation. Cool City was built by SDCJ and also they are from Japan. There are three types of transportation that will be used in Cool City like hybrid cars, water taxis and light railway. Business, commercial/ cultural and residential are the various zones in the city. There are some techniques that will reduce heat by water, trees and roof membranes. 60% is the overall percentage of reduction of CO2 emissions claimed in the video.

In my opinion, cool city is a great city because it is an environmental city. In addition the city takes care about our planet by lots of things such as tree planting ,waterways ,rooftop membranes. I hope there will be more cities in the world like cool city.
