Black Carbon and Climate Change: Exploring the Policy Options for Reducing Emissions from Diesel Fuel Consumption in the United States.
Abstract: Black carbon (BC), the main component of soot, is produced by the
incomplete combustion of carbon-rich fuels. Over the past decade, it has been recognized as
a potent climate warmer, yet to date, BC has not been explicitly targeted through any
global, regional, or national climate change policies or regulations. The U.S.
Environmental Protection Agency (EPA) has taken no formal posit... read moreion on BC as it relates to
climate. This study explores ways that the United States can best address the climate
impacts of BC, reviewing the policies or policy frameworks that could facilitate broad
reductions in domestic BC emissions, with particular emphasis on the leading sources of
domestic BC emissions: on-road and non-road diesel engines. Results of this study indicate
that the United States has a number of national- and sub-national policy mechanisms that
could facilitate accelerated BC emissions reductions from mobile source diesel fuel
consumption but has no coordinated national BC strategy. Better coordination of air-quality
and climate policies and planning is urgently needed, with a priority placed on fast action
by leveraging existing regulatory authority and policy mechanisms. Detailed policy
recommendations are offered specific to the regulatory purview of EPA, Congress, and
regional, state, and local governments to accelerate BC emissions reductions from mobile
source diesel fuel consumption.
