Recommendation
To translate GHG reductions into an equivalent number of cars off the road, annual emissions from a typical passenger vehicle should be equated to 5.5 metric tons of carbon dioxide equivalent or 1.5 metric tons of carbon equivalent.

Step 1: Determining the CO2 produced per gallon of gasoline
A gallon of gasoline is assumed to produce 8.8 kilograms (or 19.4 pounds) of CO2 -
This number is calculated from values in the Code of Federal Regulations at 40 CFR 600.113-78, which EPA uses to calculate the fuel economy of vehicles, and relies on assumptions consistent with the Intergovernmental Panel on Climate Change (IPCC) guidelines.
In particular, 40 CFR 600.113-78 gives a carbon content value of 2,421 grams (g) of carbon per gallon of gasoline, which produces
8,877 g of CO2. -
(The carbon content is multiplied by the ratio of the molecular weight of CO2 to the molecular weight of carbon: 44/12).
-
This number is then multiplied by an oxidation factor of 0.99, which assumes that 1 percent of the carbon remains un-oxidized.[1.]
-
Step 2: Estimating the fuel economy of passenger cars and light trucks (MPG estimate)
-
MOBILE6.2 (EPA’s computer model for estimating emissions for highway vehicles) can calculate an average fuel economy across the fleet, based on the EPA annual Fuel Economy Trends reports. For 2003, MOBILE calculates values of 23.9 miles per gallon (mpg) for passenger cars and 17.4 mpg for light trucks.

Note that EPA's emissions estimates are lower than estimates obtained through fueleconomy.gov, because EPA's estimates are for tailpipe emissions only. The fueleconomy.gov site estimates emissions over the full fuel lifecycle (including extraction, processing, and transportation of fuel).
-
Transportation
Pounds of carbon dioxide equivalent are calculated based on EPA's estimate of the greenhouse gas emissions from a typical passenger vehicle in the United States. Estimates of the typical values for fuel economy and miles driven per week are from the same source.

When Do the Universal Waste Regulations Apply to Lamps?
40
CFR 273.5 -
What Are the Waste Management Requirements for Small
Quantity Handlers of Universal Waste Lamps? 40
CFR 273.13(d) -
(1) A small quantity handler of universal waste must contain any lamp
in containers or packages that are structurally sound, adequate to prevent
breakage, and compatible with the contents of the lamps. -
(2) A small quantity handler of universal waste must immediately clean
up and place in a container any lamp that is broken and must place in
a container any lamp that shows evidence of breakage, leakage, or damage
that could cause the release of mercury or other hazardous constituents
to the environment. Containers must be closed, structurally sound, compatible
with the contents of the lamps and must lack evidence of leakage, spillage
or damage that could cause leakage or releases of mercury or other hazardous
constituents to the environment under reasonably foreseeable conditions. -

Environmental Benefits

Yard trimmings and food residuals together constitute 24 percent of the U.S. municipal solid
waste stream. That's a lot of waste to send to landfills when it could
become useful and environmentally beneficial compost instead!
