N2  - The study addresses the critical need for quantifying Scope 3 greenhouse gas (GHG)  emissions from passenger transportation by taxi in Vietnam, focusing on the  development of a Practical methodology for estimating Scope 3 emissions in the  absence of detailed operational data. Recognizing that Vietnamese taxi operators  primarily report travel expenses, not kilometers traveled, this study develops and  applies a practical cost-to-distance conversion methodology. The study analyzes  publicly available fare structures from major taxi operators (Mai Linh, Vinasun, G7,  VinaTaxi and travel agency) to establish a cost-to-distance conversion factor.An initial analysis of taxi fare tables yielded an average conversion value of 12,795  VND/km. However, to reflect the lower per-kilometer costs of longer-distance business  travel and potential corporate discounts, a more representative conversion factor of  12,000 VND/km was adopted. This adjusted value aligns with observed fares for trips  over 30km. Using this factor, historical and projected taxi travel costs for a case study company were converted into distances traveled, enabling Scope 3 GHG emission estimation. This cost-based methodology provides a robust and practical approach for  estimating these emissions despite data limitations in Vietnam.  This study's methodology and findings, particularly the derived cost-to-distance conversion factor, offer a valuable tool for businesses in Vietnam to estimate Scope 3  emissions from passenger taxi travel. This is crucial given the current absence of  specific national regulations, standardized emission factors from bodies like the IPCC  or GHG Protocol, or distance-based data from travel agencies or taxi operators in Vietnam. The developed conversion factor enables the crucial shift from cost-based invoices to kilometer-based data, providing a critical and currently missing link for  consistent, comparable GHG emissions calculation.Furthermore, this allows companies like Company B Vietnam to establish a baseline,  quantify their emissions impact from this significant source, and ultimately develop  informed strategies for emission reduction, contributing to both corporate and national sustainability goals into ESG journey
