Over the next 15 years, it may only cost 5% more than new transit systems, power plants, and other infrastructure already in the works would cost in order to limit emissions contributing to climate change. If we consider the health savings and fuel savings we could have that are included in this, we may actually save money. Renewable energy costs have been sharply decreasing, and some communities are trying to limit urban sprawl, reduce traffic, and use land more efficiently. These things will have to be promoted to countries around the world. Fossil fuel subsidies will have to be eliminated. Can you believe that Venezuela, a major oil-producing country, sells gasoline for 6 cents per gallon?? It is so cheap that citizens do not care about saving fuel.
"If a concerted worldwide push were made to scale up ideas that have already proved successful, the commission found, emissions of heat-trapping gases could be reduced by billions of tons per year, and the chances of limiting global warming to tolerable levels would be greatly improved."
