Summary: | A 2013 scientific assessment of black
carbon emissions and impacts found that black carbon is
second to carbon dioxide in terms of its climate forcing.
High concentrations of black carbon in the atmosphere can
change precipitation patterns and reduce the amount of
radiation that reaches the Earth's surface, which
affects local agriculture. Acute and chronic exposures to
particulate matter are associated with a range of diseases,
including chronic bronchitis and asthma, as well as
premature deaths from cardiopulmonary disease, lung cancer,
and acute lower respiratory infections. The transportation
sector accounted for approximately 19 percent of global
black carbon emissions in the year 2000. This report aims to
inform efforts to control black carbon emissions from
diesel-based transportation in developing countries. It
presents a summary of emissions control approaches from
developed countries, while recognizing that developing
countries face a number of on-the-ground implementation
challenges. This study applies a new cost-benefit analysis
methodology to four simulated diesel black carbon emissions
control projects - diesel retrofit in Istanbul, green
freight (plus retrofit) in Sao Paulo, fuel and vehicle
standards in Jakarta, and compressed natural gas (CNG) buses
in Cebu taking into account the additional climate benefits
of black carbon reductions. While this report focuses on
quantifying just the health and climate benefits of
transport interventions, it also serves to highlight the
challenges that can be faced when undertaking more
comprehensive evaluation of transport projects. A
cost-benefit framework for economic analysis of diesel black
carbon emissions control transport projects is also
presented that factors in both climate and health benefits.
Historically, technical interventions to control diesel
black carbon emissions in developed countries have
successfully relied on fuel quality improvements and vehicle
emissions standards. |
