Calculate Your CO2 Footprint

We all play a role in global climate change. Use our Carbon Footprint Calculator (Below) to determine your household's contribution to greenhouse gas production.

Instructions: Start with Step 1 to understand your household's emissions, and then use Step 2 to determine how to reduce your carbon footprint!

CO2 emissions are calculated based on this formula:

Short Haul (< 281 miles) = 1.2 Pounds CO2 per mile
Medium Haul (281 - 994 miles) = 0.85 Pounds CO2 per mile
Long Haul (> 994 miles) = 0.74 Pounds CO2 per mile

In addition, according to the European Commission’s Fifth Framework Programme’s report entitled “Tradeoff”, the full climate impact of aviation, including non-CO2 greenhouse gases (CO2e), is deemed to be 1.9 greater than that of CO2 alone. CO2e is an abbreviation of 'carbon dioxide equivalent' and is the internationally recognized measure of greenhouse emissions. The WRI multipliers have been adjusted to reflect the full climate impact.

Average number of pounds of CO2 equivalent per person per year that could be saved by recycling newspaper = 184.3

Average number of pounds of CO2 equivalent per person per year that could be saved by recycling glass = 25.6

Average number of pounds of CO2 equivalent per person per year that could be saved by recycling plastic = 46.6

Average number of pounds of CO2 equivalent per person per year that could be saved by recycling metal = 165.8
