2014 update: new version of HEAT for walking and cycling!

Today, the 2014 update of HEAT has been launched. Keeping the tool updated with the latest scientific evidence, the main new features and changes include:

  • updated relative risk functions for walking and cycling;
  • new Values of Statistical Life (VSL) with averages and country-specific values (based on a methodology developed by the OECD);
  • updated and more detailed mortality rates for European countries;
  • new section of frequently asked questions (FAQ); and
  • several bug fixes.
For details on the updated risk functions and new VSL values, please consult: Please note: The previous 2011 version of HEAT is no longer available. If you need access to assessments saved with the 2011 version, please contact us at heat@euro.who.int.


This tool is designed to help you conduct an economic assessment of the health benefits of walking or cycling by estimating the value of reduced mortality that results from specified amounts of walking or cycling.

The tool can be used in a number of different situations, for example:

  • when planning a new piece of cycling or walking infrastructure.
    HEAT attaches a value to the estimated level of cycling or walking when the new infrastructure is in place. This can be compared to the costs of implementing different interventions to produce a benefit–cost ratio (and help to make the case for investment)
  • to value the reduced mortality from past and/or current levels of cycling or walking, such as to a specific workplace, across a city or in a country. It can also be used to illustrate economic consequences from a potential future change in levels of cycling or walking.
  • to provide input into more comprehensive economic appraisal exercises, or prospective health impact assessments.
    For example, to estimate the mortality benefits from achieving targets to increase cycling or walking, or from the results of an intervention project.
