The Government of India, under the leadership of the Prime Minister, has demonstrated unwavering commitment to strengthen the logistics sector through transformative initiatives such as PM GatiShakti and National Logistics Policy (NLP). Complemented by digital tools like ULIP and dedicated freight corridors, the policy is driving a more efficient, competitive, and sustainable logistics ecosystem across India. It is, therefore, important to estimate the logistics cost for India and also track it over time, in order to assess the efficiency of initiatives and identify the areas of further intervention. This document presents the methodological framework to conduct the study on estimating the National Logistics Cost and has been prepared by NCAER and DPIIT, in consultation with the Taskforce, which was constituted to provide the guidance during the course of the study. The Task Force comprises members from NITI Aayog, Ministry of Railways, Ministry of Statistics and Programme Implementation, NCAER, academic experts, and other industry stakeholders.
