Abstract
Today teleworking is increasing rapidly, but the shift to working at home from commuting to and from the office everyday may increase an environmental burden by using inefficient equipments at home such as air conditioners. In order to calculate and compare life cycle CO_2 emissions between different work styles, we set three work style scenarios, working at office, using the telework center in worker's neighborhood and working at home. Ahead of calculating, we measured life cycle CO_2 emission of telework centers in Kanto region, Japan, because there is no inventory data of the telework center. In this life cycle CO_2, We also considered CO_2 emissions from commuting and the rebound effects attributed to the increased leisure time. Additionally, there are great differences in the each work styles among individuals, such as commuting time or energy consumption. So we did an uncertainty analysis with Monte Carlo simulation, then we found the high contribution factors of each scenarios. As a result, we found if a telework center or a conventional office is used efficiently, their CO_2 emissions become same level as working at home.
