Dealing with uncertainty in vehicle NOx emissions – update to position statement

The IAQM’s position statement, Dealing with Uncertainty in Vehicle NOx Emissions within Air Quality Assessments, originally published in October 2016, has been updated.

The amendments, which are tracked and explained in a change log at the end of the document, are primarily to reflect changes to other external documents and procedures.

All IAQM position statements can be downloaded on the right of our Guidance page. Alternatively, this updated document can be downloaded here (pdf).
