Air Quality & Emissions

Climate change and poor air quality are two of the key reasons why low emission mobility is moving up the political agenda across the world.

Our work in this areas focuses on reducing greenhouse gas emissions through the use of cleaner vehicles to lessen climate change risks, and limiting other airborne pollutants that degrade air quality with consequent health and environmental impacts.

Low Emission Car Changing

We are skilled in development, appraisal and evaluation of strategies and measures to reduce emissions, including transport policy interventions, infrastructure measures, vehicle-based measures and behaviour change programmes. 

We use a wide of transport models, coupled with state-of-the-art emission models, to appraise the range of options for reducing emissions and work with Local authorities to develop implementation plans.

  • Emissions modelling and forecasting
  • Advice and research on multiple transport technologies
  • Smarter choices and travel behaviour change
  • Low emission strategy appraisal

Greater Birmingham and Solihull low carbon transport strategy

Access to European funding opportunities is competitive and, to be successful, Local Enterprise Partnerships are required to develop coordinated regional strategies. For the Greater Birmingham and Solihull Local Enterprise Partnership this highlighted a need to develop a Low Carbon Strategy for the area.

ITP was appointed to work alongside local Councils to draw individual strategies into one coherent document. This involved building consensus across Council staff and stakeholders to reflect the different challenges they are facing.

The output of our work was a strategy document which is enabling the Local Enterprise Partnership to bid for European funding.

Low Carbon Romania

Romania climate change consultancy

Tackling the effects of climate change to create a lower carbon economy is a priority for the Romanian Government. With funding from the World Bank, ITP was commissioned to provide expert advice on integrating climate change mitigation and adaptation measures into national transport plans.

Work in-country informed our understanding of local constraints and enabled us to identify applicable experience from other countries. We then modelled the climate change mitigation impacts of different transport scenarios. 

Working alongside World Bank officers we compiled a Rapid Assessment Sectoral Analysis Report for the transport sector, which fed into Romania’s national climate change action plan. 

Nigeria low carbon emissions study

The World Bank funded this cross-sectoral study to examine the likely evolution of greenhouse gas emissions in Nigeria over the next 20 years and identify mitigation strategies.

Our role was to produce carbon emission estimates for the transport sector on a country-wide basis. We built a spreadsheet model using emission factors from the World Bank EFFECT model and established baseline ‘business-as-usual’ emissions levels derived from population growth rates, increasing incomes and economic activity leading to greater car ownership levels and demand for freight. 

A number of transport policy measures were then modelled to demonstrate how policy and transport interventions could be used by the Nigerian government to mitigate transport sector emissions.
