Do Americans believe in climate change?
PEW RESEARCH CENTER, March 13-17, 2013
Is there solid evidence the earth is warming?
2006 2007 2008 2009 2010 2011 2012 2013
Yes, solid evidencethe earth is warming
Warming mostly because of human activity
62% Norwegian forest owners
(May 2013)
Will Americans do anything about it?
What kind of priority do you think Obama and the Congress should give … (percent saying highest priority)
the economy
reducing federal spending
restructuring the federal tax system
enacting stricter gun-control laws
slowing rate of growth in spending on Medicare and Social Security
addressing gun violence
addressing immigration issues
addressing global warming/ climate change
Washington Post-ABC News poll conducted Jan 10-13, 2013 among random national sample of 1,001 adults
Will Americans do anything about it?
Should the federal government regulate the release of GHGs from power plants, cars and factories to reduce global warming?

Will Americans do anything about it?
Clean Air Act – requires EPA to regulate emissions of hazardous air pollutants from stationary and mobile sources;
– “best available control technology” (BACT) provisions;– does NOT accommodate temporal aspects of sequestration
US Supreme Court orders EPA to regulate GHGs (“endangerment”)
“Tailoring Rule” adopted – allows exemption of facilities by tonnage of C emitted, not source (e.g., biomass, fossil fuels)
3-year deferral – delayed permitting of biogenic C to conduct examination– establish Accounting Framework, and Science Advisory Board
Science Advisory Board – recommendations for biogenic C accounting
Deferral vacated by a federal court decisionNew Source Performance Standards – regulations for new coal and gas-fired
electricity; rules for existing facilities by 2014; biomass exempted
Revised Tailoring Rule – how will EPA accommodate temporal aspects without Congressional action (new Act vs. de-authorizing EPA)??

Task … restricted to biogenic carbon from stationary facilities; did not assess attributional impacts
Carbon neutrality … cannot be assumed a priori
IPCC reporting convention … does not link stationary sources to their emissions; net carbon stock approach
EPA Biogenic Accounting Framework does not consider impacts over different time
scales net carbon stock approach (regional reference
points) would exempt facilities by location, not by emissions
holding facilities responsible for carbon leakage (e.g., LUC) does not reduce overall emissions
Science Advisory Board Observations
Default equations … by feedstock category, region, prior land use, current management practices Applied at facility-level Facilities can demonstrate lower emissions
Anticipated baseline … compare emissions from increased harvesting against baseline Include soil sequestration and natural decay rates Consider alternate fates of residues/diverted
wastes
Various time scales … incorporate tradeoffs of different time scales (C-plus)
Supplementary policies … to reduce carbon leakage based on assessment of directionality if not magnitude
Recommendations to EPA
Current Debate
Temporal issues difficult to rectify – radiative forcing, albedo, etc
Incorporating periodic loss events – fire, insects, and disease Transparency – clear and consistent reference conditions EPA struggling to connect biogenic emissions to a defensible
Clean Air Act regulation – although biomass qualifies as “BACT”
Facility-level LCA calculations would slow progress; lack consistent system boundaries and data
Other Important Developments:
“Surrogate” Climate Policy – FederalRenewable Fuels Standard – 16 billion gal cellulosic biofuels by 2022Production & Investment Tax Credits – open-looped: 1.1¢/kWh; closed-looped: 2.2¢/kWhFarm Bill (Energy Title) – community biomass heating; biomass procurement and sourcingVehicle fuel standards – new vehicle emissions down 19% since 2007BTU Act (proposed) – thermal tax parity; efficiencyClean Energy Standard (proposed)
