Therefore, the idea of the pursuit of economic efficiency and fair allocation in present age is given up. Considering the Natural Environment, the fundamental environment needs for next generation is taken into consideration of development in contemporary world. Thus, it makes sustainable development for all generation. Greenhouse gases have been increasing massively since the Industrial Revolution, especially carbon dioxide(CO2),which cause many environmental issues such as greenhouse effect phenomenon, ecosystem change, climate change. Such negative effects on global climate are huge and multi-faceted, and we can learn from the international treaties about the urgency of CO2 emission reductions. According to IPCC(2007)report that CO2 concentration rise from human use fossil fuel, so it reveals that reduction of CO2 derives from fuel. Greenland can reduce CO2 concentration and attain to Self-purification function. However, humans translate green area to developed land which increase concentrations of carbon dioxide during the period of development. In terms of carbon balance, this paper tries to quantize required green areas which consider energy consumption under development of city and coexistence with nature. In this study, in order to examine whether it achieves balance state between carbon emission and carbon sequestration by green space for each county in Taiwan, carbon sequestration in green spaces are divided into two category which are Greenland in county and urban Greenland. CO2 emission and Greenland solid carbon quantity discuss Taiwan County city. The result is shown below: 1.In Taiwan, the highest CO2 emission derives from industrial department, the next is the department of transportation, and then is the residential department. It shows that the majority of CO2 emission derives from industrial department. 2.Top five counties by CO2 emission in Taiwan are Taipei county, Taoyuan county,Taichung county, Kaohsiung county, and Taipei city. The majority of CO2 emission comes from industrial department, and it occupies over 60 percent. 3.The higher development level a city has, the more energy it consumes and the higher CO2 emission per area. For Example, Taipei, Kaohsiung, Taichung, Tainan ,and Hsinchu city. In these cities, urban development land is over 90%. 4.A research of carbon balance between county and urban Greenland, we find that Urban Greenland are all unbalanced. Greenland in county which 7 of 23 counties in Taiwan are in an unbalanced state. Among these counties Taipei city, Kaohsiung city, and Taichung city are more serious, and the percentage of required land area of green area to total county area are 94%, 88%, and 55% respectively.
