| Summary: | According to a report by the World Bank
published in April 2018, air pollution in Tehran incurs
annual loss of billions of dollars and over 4,000 premature
deaths from exposure to fine particles ambient
concentrations. Particulate matter (PM), one of the primary
pollutants from diesel exhaust, is associated with many
different types of respiratory and cardiovascular effects,
and premature mortality. The main objective of this study is
to evaluate the cost effectiveness of retrofitting existing
city diesel bus fleet in Tehran with best available Diesel
particulate filters (DPFs) available in the market. The
report provides an updated assessment on the diesel retrofit
solutions for an ageing diesel city bus fleet in Tehran
based on publicly available information. The economic
benefits of DPF installed in buses are evaluated with
standard techniques of environmental economics, and
technological assumptions about how much PM emissions can be
avoided and control costs. The report highlights a number of
national, regional and local examples of effective emission
control program that exhibit best practices from around the
world. Also, it presents important features and global
experiences of successful retrofit program on heavy-duty
diesel vehicles (HDDVs), including benefit-cost analysis
from several case studies to help Tehran city leadership in
taking informed economic and policy decisions. Finally, it
recommends a set of critical actions to the government both
at the national and local level for implementation of an
effective emission control programs. |
