Abstract
It was attempted to use life cycle assessment (LCA) to evaluate environmental impacts of parks in an actual new habitation district, having population of 9, 600 and an area of 162 hectares. Carbon dioxide (CO2) emission was chosen as a global environmental impact indicator.CO2emission from land construction works of the district was estimated as 681ton-C by using combination of the input-output analysis and the process analysis.
CO2emission from material accounted for nearly 87% of the total CO2emission from the park construction works. Cement, concrete brick, and fresh concrete were major contributors to this fraction. CO2emission per area of block parks was estimated as 8.8kg-C/m2. CO2emission in the construction and operating and maintenance stage was estimated 2539ton-C assuming 30-year period of use. In order to reduce CO2emission from the park, it is important to choice low CO2emission material and design, satisfying same activities.
