Pacific Southwest, Region 9

Serving: Arizona, California, Hawaii, Nevada, Pacific Islands, Tribal Nations

Black Carbon Symposium

Sponsored by EPA's Regional Science Council

On November 14, 2012, EPA hosted the Black Carbon Symposium in San Francisco. The purpose of this meeting was to share the latest scientific advancements on black carbon public health, climate, and air quality impacts. The symposium featured several experts on black carbon to explain the basic science of black carbon and its effects on human health and global climate change.

In March 2012, EPA issued a Report to Congress on Black Carbon. This report, which had been requested by Congress, summarizes available scientific information on the climate and health impacts of black carbon.

Major Agenda Topics

  • EPA’s recent Report to Congress on Black Carbon
  • Short-lived climate forcers as a complementary strategy to greenhouse gas abatement
  • Climate effects and modeling of black carbon
  • Health impacts of black carbon
  • Developing inventories of black carbon at the state and local level
  • Climate and health benefits of historical mitigation of black carbon from diesel vehicles
  • Prospective mitigation opportunities for black carbon
  • Policy perspectives and paths forward for state and local action

Susan Anenberg

Susan Anenberg is a Senior Advisor for U.S. Cookstove Initiatives in the State Department’s Office of the Secretary’s Global Partnership Initiative. Susan is on detail to the State Department from EPA’s Office of Air and Radiation, where she leads evaluations of the health and climate benefits of air pollution mitigation, both within the U.S. and globally. She is a lead author on several major publications related to international transport of air pollution and emission control measures that achieve simultaneous benefits for climate change and air quality. She recently led the quantification of the global air quality and health co-benefits that could be achieved by mitigating near-term climate change through black carbon and methane emission control measures.

Dr. Susan Bauer
Research Scientist
The Earth Institute at Columbia University and NASA Goddard Institute for Space Studies

Susanne Bauer is a research scientist at the Goddard Institute for Space Studies and the Earth Institute at Columbia University in New York. She is an expert in atmospheric chemistry and climate modeling. Her research activities focus on improving the representation of aerosols in global climate models by incorporating process level understanding of aerosol microphysics and chemistry.

Climate change and air pollution have, to a large extent, a common cause emissions from fossil fuel burning. Up until now however, these two problems have been addressed by separate policies. Susanne’s research focuses on developing complex atmospheric models, combined with a strong link to field, laboratory and satellite measurements, in order to apply these models to answer socioeconomic questions to support more integrated and effective policies.

She received her Ph.D. from the Max-Planck Institute für Meteorologie in Hamburg, Germany, and has spend her post-doc years at the Laboratoire des Sciences du Climat et de l'Environnement in Paris, France, before she joint Columbia’s Earth Institute almost a decade ago.

Mr. Blumenfeld has spent nearly two decades on the front-lines of protecting the environment both at home and internationally. His priorities at EPA include strong enforcement; environmental justice; protecting and restoring our air, land and waters; building strong federal, state, local and tribal partnerships; and taking action on climate change.
During his tenure at EPA Mr. Blumenfeld has taken a number of significant actions including: designating the Los Angeles River as a “protected” under the Clean Water Act; stewarding a comprehensive judicial settlement to improve the water quality for Honolulu; protecting over 5,000 square miles of California’s coastal waters by proposing to ban discharge of sewage from cargo vessels and cruise ships; bringing together diverse stakeholders throughout the San Joaquin Valley to develop solutions to some of the nation’s worst air quality problems; and leading innovative efforts and building partnerships to support the economy, environmental justice communities and air quality in the Goods Movement sectors (ports, rail, truck).

Before becoming Regional Administrator, Mr. Blumenfeld was the Director of the San Francisco Department of the Environment where he spent eight years as the primary environmental decision-maker for the city. Jared helped to initiate many landmark environmental laws that became part of the municipal Environment Code. These included San Francisco’s ban of plastic bags, a 2020 zero waste goal, LEED Gold building standards, and an overarching precautionary principle framework.

Mr. Blumenfeld’s environmental leadership includes, chairing the first United Nations World Environment Day hosted by the United States - Green Cities: Where the Future Lives (2005), overseeing the Treasure Island Redevelopment Authority, directing international initiatives to protect eight million acres of wildlife habitat and editing an annual report on international environmental case law at Cambridge University.

Dr. Veerabhadran Ramanathan

Dr. Ramanathan discovered the strong greenhouse effect of CFCs in 1975 and along with R. Madden, predicted in 1980 that global warming would be detected by 2000. In 1985, he led the first international NASA/WMO/UNEP assessment on the climate effects of non-CO2 greenhouse gases and concluded that they are as important as CO2 to global climate change.

He was among a team of four which developed the first version of the US community climate model in the 1980s. He led an international field experiment in the 1990s, with Paul Crutzen, that discovered the widespread Atmospheric Brown Clouds (ABCs) over S. Asia, which have devastating health and climate impacts. He developed light weight unmanned aerial vehicles to track pollution plumes from S. Asia, E. Asia and N. America. His recent finding is that mitigation of short lived climate pollutants (black carbon, methane, ozone and HFCs) will slow down global warming significantly during this century. This proposal has now been adopted by UNEP and 12 countries including USA.

He now leads Project Surya which will mitigate black carbon emissions from solid biomass cooking in S. Asia and Kenya. His awards include the Tyler prize, the Volvo Prize, The Rossby and the Zayed prize. He has been elected to the US National Academy of Sciences, American Philosophical Society, the Pontifical Academy by Pope John Paul II and the Royal Swedish Academy of Sciences. In 2012, he was honored by Pope Benedict with an appointment to the Council of the Vatican Academy.
