International workshop on solutions for eliminating Diesel and gasoline emitted soot from urban air

(Background, lessons learned in Europe, solutions for Tehran)

Motivation

High air pollution in Iranian cities is of highest concern to authorities in view of public health. PM2.5 is the criteria pollutant and high share of the composition is soot or black carbon. Ultrafine soot particles (UFP) are present in large numbers in the breathing air of Tehran. The anthropogenic sources of PM2.5, soot, and UFPs are combustion engines of mobile emission sources with dominating effects of diesel vehicles.
Several programs at the local and national levels aims at reducing combustion generated particles. The very first Iranian Low Emission Zone (LEZ) for Tehran, diesel particulate filter (DPF) retrofit of public transit buses, elimination of carburetor gasoline motorcycles and replacement with electric bikes are among those mitigating measures. The Iranian government already in April 2014 published a new Emission Legislation which requires DPF for all Diesel Vehicles, which will be implemented in two phases in September 2016 and September 2017.
Vehicle Industries, domestic as well as importing from Europe, Japan or China and emission experts are now challenged to comply according to best available technology.
This conference on Best Available Technologies is directed to support the introduction of Diesel Particle Filters, which are World Wide known as the only technical option to eliminate Ultrafine particles (UFP) efficiently. The conference is organized by UNESCO chair in water and environment management for sustainable cities, co-organize by VERT association of BAT filters and Tehran air quality control. Co.
