The TRUE rating system is intended to measure and rate the magnitude of real world emissions from various vehicle models under a wide range of operating conditions and driving behaviors.

This paper analyses data from European remote emissions sensing campaigns and introduces new methodology to improve the analysis of remote sensing information.

Under the Bharat Stage VI and V standards, India will achieve significant reductions of NOx and PM from agricultural tractors and construction equipment.

This position brief makes specific recommendations regarding the adoption of RDE testing in India. The recommendations are geared towards ensuring that implementation of an Indian RDE program would narrow the gap between laboratory and on-road emissions performance of vehicles that should meet Bharat Stage (BS) VI emissions standards.

A comprehensive overview of vehicle remote sensing, an emissions measurement technique which has been used for more than 25 years to evaluate emissions from passing motor vehicles in real-world driving. Reviews technical details of the vehicle remote sensing test method, describes the multiple types of emissions analyses that can be conducted with remote sensing data, and explores areas where remote sensing can supplement emission test methods currently used in the European Union light-duty vehicle regulatory program.
