SENCO Sustainable Environment Consultants


Road transport projects

Road transport is a major source of pollutants that degrade air quality and cause global warming. In richer countries, tightening emission standards will reduce the emission of many noxious pollutants per vehicle kilometre, but traffic growth may counterbalance this such that emissions start to increase in the longer term. Presently there is little regulation of fuel use and carbon dioxide emission.

SENCO has worked extensively on the modelling of emissions from road transport,  abatement strategies and their cost minimisation, and the effects of emissions on air quality.

A presentation on the first European Auto Oil Programme can be found here. It describes the evaluation framework, and the combination of technical and non-technical measures modelled to reach air quality standards.
