1 Cap and Trade I. Introduction Greenhouse effect is an important and difficult issue that we are facing because of global warming. It’s the greatest challenge in 21 st century and directly relate to our development and survival. The CO2, CH4, nitrogen and other gases can make the sun expose to the Earth directly, but block the infrared from the Earth to the Universe. The gases absorb the infrared and sun light, then transform to heat to increase the humidity on Earth’s surface. This phenomenon is called greenhouse effect. Greenhouse gases are mainly CO2 count for 60%. (Global Warming, 2010)The higher consistency of the gases, the higher temperature nears the surface. Without the greenhouse gases, the Earth temperature will drop to very low. Millions of years, Earth has benefited from the greenhouse effect, because it has created a comfortable environment for all living life. After the industrial revolution of the 1700’s the greenhouse effect was enhanced by greenhouse gas emissions of anthropogenic nature. (Appendix D) The main source of anthropogenic greenhouse gas emissions is fossil fuel combustion. The contribution of greenhouse gases to the greenhouse effect varies. The greenhouse effect not only impacts the environment, it also has social and environmental consequences, such as large-scale migration and mitigation issues between countries. Both political and environmental NGO’s try to gain support for the introduction and execution of solutions to the greenhouse effect. But despite the many actions of environmental organizations not every country accepts the greenhouse

8 effect as a global environmental problem. Many believe that the theory holds some truth, but the consequences are largely exaggerated. (Greenhouse Effect ) I. Cap-And-Trade: Problems and Prospects Human activities has increased greenhouse effect, and caused climate change. Since the industrial revolution, lots of resources and energy consumptions have increased CO2, especially coal, oil, cars and other emissions. It is estimated about 240 million tons of CO2 has been discharged to the atmosphere every year and it’s increasing. According to the 2007 Fourth Assessment Report by the Intergovernmental Panel on Climate Change (IPCC), global surface temperature increased 0.74 ± 0.18 °C (1.33 ± 0.32 °F) during the 20th century. (It is illustrated in Appendix A .) The latest IPCC report indicates that the global surface temperature is likely rise to a further 1.1 to 6.4°C during the 21 st century. On July 7, the Energy Information Administration (EIA) released its July Short-Term Energy Outlook , which indicated that total U.S. carbon dioxide (CO2) emissions are expected to increase by 3.2 percent in 2010 and by 1.6 percent in 2011. (Global Warming ) The increasing environmental problems have caught every nation’s attention. Cap and trade system is an effective way to control the problem but not eliminate the
