To reduce greenhouse gas emissions, ports around the world are considering using electric cargo handling equipment. To assess the benefits of the strategy, this study provides a comparative life-cycle assessment between diesel and electric yard tractors in a case study of the Port of Los Angeles. Results indicate a significant reduction in life-cycle emissions as the port shifts to electric vehicles and as the port's electricity supplier increases its use of renewable energy sources (e.g., wind and solar). The results also demonstrate that even with aggressive electrification strategies, the port's legislated reduction targets are not achievable by the year 2030.
