Analysis – Overall HCFC Agreement

POTENTIAL CLIMATE BENEFITS OF NEW STRONGER HCFC PHASEOUT CONTROLS
	A Transition from HCFCs to Currently Available Substitute Technologies (often using other high global warming gases) †	Mid Point	A Transition from HCFCs to No- or Low-GWP Substitute Technologies †
Reduction in MMTCE (million metric tonnes carbon equivalent) [CO2-eqivalent]	750 [2,750]	2,575 [9,442]	4,370 [16,023]
US passenger cars off the road each year for next 30 years ª *		68,100,000
Percentage of US fleet of passenger cars taken off the road each year, for the next 30 years		53%
US households not using electricity for each year over the next 30 years ª **		40,400,000
Percentage of US households not using any electricity for a year, for the next 30 years		38%

† Calculations from the USEPA analysis of HCFC Consumption and Emissions arising from U.S. adjustment proposal for HCFC phaseout and the transition to substitute technologies, report developed by ICF International (ICF 2007)

ª Calculations taken from the US Climate Technology Cooperation Gateway website that is sponsored by USEPA and USAID. (soon to be updated)

* Number of passenger cars in the States is based on 127.7 million registered vehicles in 2001 with average gas mileage of 23.9 mpg and the calculated CO2 emitted per gallon of gasoline burned of 8.781 kg (soon to be updated with new "gateway")

** Number of households and energy use is based on 105.2 million households in 2000 from USDOE's publication "2002 Buildings Energy Databook" with a national average CO2 output of 1,392 pounds per megawatt-hour (soon to be updated with "gateway")
