The Decarbonization of Rural Bus Routes project, under the EU Just Transition Fund Implementation Plan (Action 3.1), aims to transition Transport for Ireland (TFI) Local Link rural bus services to a low-/zero-emission fleet. This initiative will see the installation of new fast/very fast electric charging infrastructure at key locations and the procurement of electric battery buses (EBBs) to enhance sustainable mobility. The project aligns with national strategies, including the Climate Action Plan, National Sustainable Mobility Plan, Our Rural Future Development Policy, and the Connecting Ireland Rural Mobility Plan, which seeks to expand public transport accessibility in rural areas. Additionally, the project includes training for bus drivers on efficient electric vehicle operation. Implemented in three phases—Route Assessment, Procurement, and Build & Handover—this intervention supports Ireland’s commitment to sustainable transport while improving connectivity and accessibility in rural communities.
