Under worldwide environmental stress, zero-emission vehicles (ZEV) are rapidly coming to market. However, it is not clear how such vehicles reduce vehicular emissions at a spatially explicit level, which is crucial for developing specific policies. This study proposes a quantitative approach to estimate the effectiveness of ZEVs in reducing emissions in order to support investment decisions promoting the usage of ZEVs. The approach utilizes existing statewide travel demand and mobile emission models in an integrated framework. Scenarios are designed to measure the emissions reduction effects of ZEVs at different spatial scales (statewide, county, roadway) and characteristics (densely and sparsely populated counties) and with various levels of market penetration and driving range limits. The results show significant spatial differentiation of the impact of ZEV deployment from county to roadway levels. Offering greater spatial detail and new insights on decision-making process, this study describes an integrated tool for identifying effective strategies for ZEV implementation.
