Scope: This document provides guidance on the principles, evaluation scope, and procedures for quantifying greenhouse gas emissions reductions achieved by citizens who stop driving their vehicles and adopt alternative modes of transportation, as well as the evaluation content and data quality management. This document is applicable to greenhouse gas emission quantification assessments conducted by citizens or mobility platforms on vehicle-free travel behaviors. Note: In this document, "motor vehicles" specifically refer to non-commercial fuel-powered, pure electric, and hybrid passenger cars (i.e., private cars) held by citizens with valid driving licenses.
