Low emission strategies

Low emission strategies

An integrated approach to improving urban air quality

There is no silver bullet that will solve all the air pollution problems in your city.  An integrated approach is needed pulling together a range of complementary measures that not only solve air quality problems but help mitigate carbon emissions and ensure a vibrant and liveable city for your residents.  Ricardo can help you build such an integrated approach to air quality management that we term a ‘Low Emission Strategy’.  The key steps in this approach are:

  1. Understanding the problem – using both monitoring and modelling data to understand where and what is causing the air pollution problem in terms of key sources and activities.  Our monitoring and modelling capabilities can underpin this work, along with our experience of working with traffic model and data
  2. Developing potential solutions – building on our knowledge of mitigation measures and working with key local stakeholders both in the city authority and key business, such as transport operators, we explore what plans and policies are in place and what additional solutions could be implemented.
  3. Assessing the impact of these solutions – using our modelling tools we can then assess the impact of these measures on emissions, both air pollution and climate related, to understand the impact they will have both individually and as packages.  This assessment may also draw on existing transport models to better under transport responses to measures.
  4. Identifying a cost-effective package – building on the emissions results we carry cost benefit analysis to understand which packages of measures provide the greatest overall social benefit.  As part of this we look at how the benefits and costs are distributed across different social/stakeholder groups to ensure an equitable solution is generated.
  5. Setting out an implementation strategy – covering how solution are procured, public and stakeholder engagement activities, financing opportunities and delivery timescales.

This approach has under pinned our work with cities in developing Air Quality Action Plans, Clean Air Zones and Low Emission Zones.  It has provided a robust evidence base that has allowed clear policy making and supported investment business cases.  Working in this way we have help cities secure significant investment in low emission vehicles, sustainable transport measures and access management and charging schemes.
