Criteria Pollutant Health Damages • Fann et al. 2012 • Uniform Value of Statistical Life • Krewskiet al. (2009) • Laden et al. (2006) • Muller et al. 2011 • Value of Statistical Life age differentiated • Pope et al. (2002) Photo Credit: Drawn by Theresa Knott Commons.wikimedia.org/wiki/File:Respiratory_system.svg
Climate Change Damages • Social Cost of Carbon • Interagency Working Group of the US Government • Discount Rates • Central 2 of 4 estimates in report • 3% for low • 2.5% for high • Applied to CH4 using GWP(100) = 28 (Myhre et al. 2013)
MARKAL Dan Loughlin US EPA ORD 2011 MARKAL finds least cost way to meet energy demand
MARKAL updates • Results shown here use an edited version of EPAUS9R_12_v1.1 • Emissions • Upstream emissions • Better natural gas representation • Renewable technologies including biomass • Sector specific emissions definitions • Calcination CO2 emissions from cement are included • More industrial technologies • Solar process heat • Emissions controls (NOx, SO2, PM, CO2) • Efficiency improvements (boiler optimization) • Refinery emissions controls (SO2, PM, NOx, VOC) • Light duty vehicle hurdle rate reduced to 18% • Coal EGU lifetime limited to 75 years from initial use • Applicable changes made to 2012 database are currently being incorporated into 2014 release • Renewable cost projections from NREL
Policy Implications • Indicate energy system changes with fees • Economically efficient emissions levels
High Criteria Pollutant fees lead to industrial efficiency improvements
Criteria pollutant fees have little effect on GHG emissions.
Considerations • Damages fixed in space and time • Fann et al. 2012 vs. Muller et al. 2011 • Fann et al. has much larger effect on industrial technologies • GHG high vs. low • Values closer than for criteria pol. cases • High is approx. 1.4x low ($/ton) • Additional reduction in electric coal with high fees % reduction from BAU
