Project Abstract

The REDMAP project aims to measure, model and project real emission of key air pollutants (including NO, NO2, PM and Ammonia) from in-use vehicles in Dublin. Emissions from real-world driving are often higher than estimated emission levels presented in the national inventory based on Euro emissions standards and type-approval tests; consequently the air quality in cities has not improved as originally anticipated from fleet renewal and stringent emission regulations. To address this discrepancy, this project will measure & model real world emissions using Remote Sensing (RS) and Portable Emission Measurement Systems (PEMS) independently and in combination. The real emission contribution of different vehicles considering Euro standard, fuel type, make, and categories and vehicle modifications will be utilised to improve the existing emission inventory generated using literature values. A new traffic-emission model and paired air quality model estimating pollutant concentrations will be formulated based on real-world emission factors (RD-EF). The modelling framework will illustrate the potential environmental, economic and health impacts of real emission due to new Real-Driving Emission (RDE) legislation, related policy changes and future growth considering scenario based modelling. The project will generate guidelines on measures and opportunities to reduce actual vehicular emission on roads in Dublin.
