What is a “carbon footprint”?  Total carbon emissions of a person or organization from all sources, both direct and indirect, over one year.  Direct: burning natural gas in a furnace  Indirect: using electricity generated by a coal-fired powerplant  Total carbon emissions of a person or organization from all sources, both direct and indirect, over one year.  Direct: burning natural gas in a furnace  Indirect: using electricity generated by a coal-fired powerplant

Typical personal carbon sources  Driving a car  Lights and heat  Travel  Food  Consumer goods  Building materials  Driving a car  Lights and heat  Travel  Food  Consumer goods  Building materials

Going on a carbon diet  A Carbon Diet is similar to a food diet  Start by assessing your current weight (of carbon dioxide)  Calculate a carbon footprint to find your “current weight” of carbon dioxide emissions  A Carbon Diet is similar to a food diet  Start by assessing your current weight (of carbon dioxide)  Calculate a carbon footprint to find your “current weight” of carbon dioxide emissions

Going on a carbon diet  Determine your ideal weight  Measure your carbon footprint against your peers  Determine your ideal carbon footprint  Identify sources of carbon emissions  Reduce by starting with the most significant sources first  Determine your ideal weight  Measure your carbon footprint against your peers  Determine your ideal carbon footprint  Identify sources of carbon emissions  Reduce by starting with the most significant sources first

Why would you diet?  CO 2 is a significant cause of global warming  Human activity is a significant cause of CO 2  CO 2 emissions relate to individual choices  Individual initiative is necessary because market forces or legislation will not be powerful and timely enough  Each individual should take responsibility for his or her share of carbon emissions  CO 2 is a significant cause of global warming  Human activity is a significant cause of CO 2  CO 2 emissions relate to individual choices  Individual initiative is necessary because market forces or legislation will not be powerful and timely enough  Each individual should take responsibility for his or her share of carbon emissions

Or, why not a carbon diet?  Other causes are important  It’s natural, such as volcanos or the sun  Many emissions cannot be attributed to individuals  Markets or politics will correct human activity  Population growth invalidates the calculations  One cannot limit everyone to equal emissions  Other causes are important  It’s natural, such as volcanos or the sun  Many emissions cannot be attributed to individuals  Markets or politics will correct human activity  Population growth invalidates the calculations  One cannot limit everyone to equal emissions

The planetary gamble  “If humanity wishes to preserve a planet similar to that on which civilization developed and to which life on Earth is adapted, paleoclimate evidence and ongoing climate change suggest that CO2 will need to be reduced from its current 385 ppm to at most 350 ppm.  “If the present overshoot of this target CO2 is not brief, there is a possibility of seeding irreversible catastrophic effects.”  “If humanity wishes to preserve a planet similar to that on which civilization developed and to which life on Earth is adapted, paleoclimate evidence and ongoing climate change suggest that CO2 will need to be reduced from its current 385 ppm to at most 350 ppm.  “If the present overshoot of this target CO2 is not brief, there is a possibility of seeding irreversible catastrophic effects.” Dr. James Hansen, NASA/Goddard Institute for Space Studies, et al
