 Carbon and air quality management
STS has extensive experience of the technologies and measures that can help to reduce global and pollutant emissions from transport, one of the key sources of greenhouse gas emissions and contributors to poor air quality in urban areas.
|
STS can support the development of carbon reduction and air quality management strategies by minimising transport energy use and careful selection of technologies that can assist in the reduction of local pollutants such as NOx and particulates. STS expertise includes:
|
 Vehicle emissions auditing, modelling and forecasting
|
Low emission technologies: hybrid and electric vehicles and gas fuels
|
Traffic management strategies: low emission zones and access control
|
Traffic reduction measures and schemes to promote modal shift
|
For carbon emissions, STS has developed an audit tool to help organisations quantify their transport CO2 emissions, and can advise on the most effective carbon abatement options. Use the the tool is usually coordinated with an STS assessment of fuel use monitoring and emissions data collection processes.
|
Regarding air quality, STS is able to model emissions of nitrogen oxides (NOx) and particulates (PMs) based on fuel use and vehicle drive cycle. STS members have been instrumental in the development of Low Emission Zones (LEZ) and were closely involved in the initial development of the London LEZ.
|
Since 2003, STS has managed the BAA Heathrow Clean Vehicles Programme (CVP). The CVP helps operators at Heathrow identify and implement cost-effective measures for improving the environmental performance of their transport operations.
