n:vision Environmental Impact:

 CO2 Emissions Prevented
66,700,000

Total Cars Off the Road
1,129,700

Total Trees Planted
45,497,940

How are the savings calculated?

Estimated savings are based on the 200 million plus CFLs that TCP, Inc., together with its key retail partners, have sold in 2007 through the end of October.  TCP is the manufacturer of n:vision CFLs.  

CO₂ savings

(Incandescent Watts – CFL Watts) x life of CFL bulb x 1.45 LBS

*1.45 LBS is the amount of CO₂ generated by 1 kWh of electricity (from US Energy Information Administration).

Equivalent of CARS taken off of the road

(CO₂ Savings x  the number of bulbs sold)
---------------------------------------------------
                          118,083

*118,083 are the average CO₂ emissions over the life of a car that would be generated (from US Department of Transportation).

Equivalent of TREES planted

(CO₂ Savings x number of bulbs sold) 
-----------------------------------------------
                        2932

*2932 is the amount of CO₂ absorbed by trees over the 100 year life in pounds.
