Helping you to understand real-world driving emissions and the environmental impacts
Ricardo Energy & Environment and its technology partner OPUS Inspection, use state-of-the-art vehicle emission measurement technology to ensure that policy focuses on only the most polluting sectors of the vehicle fleet. By accurately measuring real-world driving emissions, we deliver the local insight necessary to inform the cost-effective design of low-emission policy.
Our remote sensing equipment accurately measures real-world driving emissions from thousands of vehicles, under actual driving conditions, in a short space of time and without interfering with the vehicle whose emissions are being measured.
Our systems are configured to measure realworld driving emissions of nitric oxide, nitrogen dioxide, particulate matter, hydrocarbons, carbon monoxide and ammonia. Bespoke measurement campaigns are designed to explore real-world driving emissions at locations selected to maximise the benefit to the design of low-emission policies.
Ricardo has world-leading expertise in vehicle emissions measurement including an advanced Vehicle Emissions Research Centre and extensive expertise in the use of Portable Emissions Measurement Systems. Our deep understanding of and expertise in vehicle emissions, air pollution in general and vehicle emissions remote sensing supports:
The design and development of cost effective, evidence-based, Clean Air and Low Emission Zone strategy and pollution mitigation schemes through:
- Real-world driving emissions measurements that accurately characterise the vehicle fleet mix, identifying the most polluting vehicle types (i.e. buses, heavy goods vehicles, vans and cars) and their respective contributions to emissions.
- Quantified and highly disaggregated emissions data to underpin robust mitigation measures.
- Assessing abatement technology performance over time.
- Measurement data to support compliance management within Clean Air and Low Emission Zones.
The improvement of local air quality emissions inventories and modelling through:
- The provision of vehicle-emissions data that are consistent with existing vehicle classes used in emission factor and emission inventory development.
- Accurate road traffic counts and detailed vehicle information via automatic number plate recognition (ANPR).
- The delivery of insights such as the fraction of primary nitrogen dioxide emissions and the potential for ammonia emissions from modern selective catalytic reduction technologies.
- Significantly reduced modelling uncertainty for baseline and mitigation scenarios by removing assumptions and replacing them with evidence-based, real-world driving emissions information.
- High-volume sample sizes, at multiple locations, ensuring the evidence base is representative of the fleet in the area of interest.
- Optimisation of model performance at key road links.
