cool cities

All over the world, communities are taking action to help solve global warming. From hybrid vehicles, green buildings, and homes powered with renewable energy to what we eat, all lead to a healthy environment which has fewer carbon emissions. We need to reduce CO2 emissions by 50%.

Japan is a developed and competitive country of the industrialized and developed world. In Japan, over the last 30 years GDP has gone up 100% but energy efficiency has increased 37%, oil consumption has fallen 8%. 90% of carbon emissions come from buildings and transportation. The cool city is the city which is very friendly to the environment with fewer carbon emissions. It is being built by SDCJ, a group of Japanese companies.

The environmental cities are using three types of transportation which are hybrid cars, water taxis, and light rail transit.

There are 3 main zones in cool cities, which are: Business, Cultural, and Residential.

It uses techniques which help to reduce the heating e.g. tree-planting, waterways, and rooftop membranes.

The percentage of expected CO2 reductions for eco-towers is 50% & for eco-residences 30%.

Overall reduction of CO2 emissions is expected to be 60%.

How practical/ realistic is the video?

It is a very good and successful project, because it is all concerned about how to keep the environment protected , but it will need a lot of planning, organizing, and controlling, and all of it will take a long time to be prepared well. In addition it will lead to changes in the life styles, and in the transportation system
