Abstract: This study examines the technical efficiency and environmental efficiency of bus transit firms using the slack-based measures (SBM) and non-separable slack-based measures (NSSBM) models with and without considerations of desirable and undesirable outputs. A case study based on data from 12 bus transit firms for the years 2007 to 2011 was conducted. Empirical results show that technical efficiency was affected by environmental pollution constraints from 2007 to 2011. The study has more general theoretical implications for the externalities literature as well. (C) 2016 Elsevier Ltd. All rights reserved.
