Cool city

Since the start of the industrial revolution we are experiencing a huge increase in economic development and due to this increase there are problems such as traffic congestion, population pressure and energy consumption. If these problems aren’t solved as soon as possible we need to find another planet to live there; to solve this problem we have to decrease the amount of carbon dioxide emitted into the air by 50% so we can live in the earth. In Japan during the last 30 years GDP has doubled while energy efficiency has increased by 37% and oil consumption has decreased by 8%. 90% of carbon dioxide emitted into the air comes from buildings, which is 55% and 35% from transportation.

Cool city is an environmental-friendly city which is developed by SDCJ in Japan and they will build environmental cities in the Gulf region. The cities will be linked with a public transportation system that will be using solar water taxis, hybrid-cars and light-rail transit. The cities contain three main zones, residential, commercial and business. The cities will use various techniques to reduce heat like tree planting, water channels and wind power. They expect CO2 reduction from two types of buildings eco tower and eco residential which both of them will reduce CO2 by 80%; finally the overall percentage of CO2 reduction will reach 60 %.

My opinion:
In my opinion I think they must build more environmental cities because it decreases the CO2 level that is emitted from building. Also, I think that the environmental cities are not the only solutions for this problem. All the world must agree on the Kyota agreement so they all reduce their CO2 emissions.
