Ports as an industry account for ∼3% of the total greenhouse gas (GHG) emissions worldwide. The Port of Chennai, India, uses an enormous amount of electricity and diesel for intermodal transportation of goods and for other essential services. The inventory of GHG emissions in the Port of Chennai is made by accounting the various facilities of the port along with the housing colony and fishing harbor which come under the management of the Port of Chennai. Quantification of GHG emissions is made following the guidelines of the Intergovernmental Panel on Climate Change (IPCC) and World Port Climate Initiative (WPCI). The estimation of GHG emissions showed that 280,558 tonnes of CO2e/year was generated from the port and port-related facilities. Several GHG mitigation strategies and their impact are quantified and discussed. The technology suggestions presented in the paper will be very useful to plan effective mitigation strategies incorporating technological advancement and management policies.
