Color how many acres of forest, garbage trucks of waste recycled, or wind turbines can offset car emissions
The four activities for this section were derived from the Greenhouse Gases Equivalencies Calculator - Calculations and References by the United States Environmental Protection Agency (EPA)
The calculations were made for the following equivalences:
round(4.73 / 1.06) = 4 acres of North American pine forest is equivalent to taking one car off the road for a year
round(22.06 / 4.73) = 5 cars taken off the road for one year is equivalent to one garbage truck of waste recycled instead of landfilled
round(4.73 / 0.039) = 121 urban trees planted and grown for 10 years is equivalent to taking one car off the road for a year
round(3960 / 4.73) = 837 cars taken off the road for one year is equivalent to the carbon emissions that one wind turbine installed offsets
Python scripts is available in the code repository to generate or extend this activity. The scripts in the folder will simply execute the calculations made above and in some cases, output an svg with the relevant activity.
