Provides a guide for fleet operators on retrofit diesel abatement for particulate matter. It also includes information on technical options, benefits and costs. It aims to be a starting point on particulate matter abatement rather than a holistic guide.


It reviews the laws applicable with emission standards. Furthermore, it reviews commercially available options for retrofit exhaust abatement.

Key Findings:

  • Wall flow filters reduce PM emissions potentially by more than 95% in terms of mass and more than 99% in terms of numbers.

  • Partial flow filters potentially reduces PM emissions by greater 30 – 60%.

  • Diesel oxidation catalysts reduce PM emissions in terms of mass by less than 25%.
