Treading Lightly with Your Footprint Larry Foster
Today’s Map What’s a Footprint What’s a Footprint “The Culprits” “The Culprits” Red-Faced Speaker Red-Faced Speaker Your Turn! Your Turn! - At Home & Work - Zipping Around UAA’s Turn UAA’s Turn Food Map, Please!
Ecological Footprint Amount of BIOPRODUCTIVE land & sea area in continuous production to supply all you use and absorb your waste, using prevailing technology. ------ Jim Merkel Amount of BIOPRODUCTIVE land & sea area in continuous production to supply all you use and absorb your waste, using prevailing technology. ------ Jim Merkel Units in acres or m 2 or PLANETS Units in acres or m 2 or PLANETS Ice Area?
Carbon Footprint If you died a year ago, how better off is the atmosphere? If you died a year ago, how better off is the atmosphere? -- esteemed scholar -- esteemed scholar Larry Foster Units in CO 2 lbs or kg Units in CO 2 lbs or kg kilograms?
Where Does CO 2 Come From? From Natural Sources From Natural Sources From Human Activities From Human Activities All Natural Bear!
Combustion = CO 2 Credit: Deborah L. Williams Fossil Fuels

(National Oceanic and Atmospheric Administration 2006) The most carbon dioxide in 650,000 years. (IPCC 2007) Credit: Deborah L. Williams Global Temperature & CO 2
These Pollutants do What? – Global Fever Greenhouse gases cause the earth to heat up the same way that a person sleeping under a thick blanket in the summertime is too hot…or wearing a parka that is too thick. Our atmospheric “blanket” or “parka” is over 35% “thicker”. Thick blanket traps too much heat.Thinner blanket is “just right”. Credit: Allison Butler
Credit: Deborah L. Williams “Recognizing the risk of climate change, we are taking actions to improve efficiency and reduce greenhouse gas emissions in our operations.” Exxon Mobil December 2006 “When 98% of scientists agree, who is Shell to say, ‘let’s debate the science’ [about global warming]?” Shell Oil November 2006 “Human activity, including the burning of fossil fuels, is contributing to increased concentrations of greenhouse gases in the atmosphere that can lead to adverse changes in global climate.” ConocoPhillips Just in Case Your Were Wondering
Danger Will Robinson – danger danger!! Most models UNDER estimate impacts and OVER estimate capacity. Most models UNDER estimate impacts and OVER estimate capacity. Who’s Will?
Time to Compare Experimenting with Experimenting with my students Call the IRB!
As of just three weeks ago! Math? Tons CO2 Earths
Message of the Day! To Reduce Your Carbon Footprint – Reduce Your Ecological Footprint! Seems Too Simple
Computing the Ecological Footprint By hand: “Radical simplicity – small footprints on a finite Earth” by Jim Merkel By hand: “Radical simplicity – small footprints on a finite Earth” by Jim Merkel Web model for Web model for Ecological Footprint: http://www.myfootprint.org/en /visitor_information http://www.myfootprint.org/en /visitor_information http://www.myfootprint.org/en /visitor_information Do it now!
Computing the Carbon Footprint CO 2 Equivalence. CO 2 Equivalence. Web model for Carbon Footprint: www.nature.org/initiatives/climatechange/calculator Web model for Carbon Footprint: www.nature.org/initiatives/climatechange/calculator www.nature.org/initiatives/climatechange/calculator oh, that gas
Need a victim! Just what is MY footprint? Just what is MY footprint? embarrassing!
So who cares... Global Warming Global Warming Ocean Acidification Ocean Acidification hey stupid – I do!
Ocean Acidification 525 BILLION tons 525 BILLION tons of CO2 into the Ocean in last 200 years ½ of Human Emissions ½ of Human Emissions MILLION BILLION lbs
But where is the Acid? pH goes from 8.21 to 8.1 in 200 years pH goes from 8.21 to 8.1 in 200 years Why? Drink a COKE! Why? Drink a COKE! 7-Up is better!
So what – just 0.11! Its all in the Math: Its all in the Math:10^0.11 Looks hard!
30% - yeeks! Its all in the Math: Its all in the Math: 10^0.11 ~ 30% forget swimming!
and Acids do what? Sea life at the bottom of the food chain need calcium carbonate. Sea life at the bottom of the food chain need calcium carbonate. Acids bind with carbonate preventing shell formation Acids bind with carbonate preventing shell formation I’m on top of this!
Did you flunk chemistry? Its all about TUMS. Its all about TUMS. Great Web Source: Great Web Source: Alaska Marine Conservation Council www.akmarine.org Actually, an A+
Any more BAD News? Business as usual: Business as usual: 10^0.4 ~ 250% by end of century Miss 20 Million BCE? Hot Chiles!
But that’s the rest of the world! BAD NEWS – Impacts the cold polar and sub-polar regions first! BAD NEWS – Impacts the cold polar and sub-polar regions first! Bummer!

Your Turn! First - Do Your Foot Prints First - Do Your Foot Prints Home Ideas Home Ideas Work Ideas Work Ideas At the Fridge! At the Fridge! Zipping Around Zipping Around Going Neutral Going Neutral I’m already on it!
At Home Turn it off – turn it down Turn it off – turn it down Upgrade Upgrade Do an audit Do an audit Compost & recycle Compost & recycle 70 times Trash 70 times Trash Off - stupid!
More Home Ideas Buy local – buy green Buy local – buy green Buy “Recycled – Post Consumer” Buy “Recycled – Post Consumer” Stop Junk Mail Stop Junk Mail Don’t Forget: Reducing your Eco Print means Reducing your Carbon Print Don’t Forget: Reducing your Eco Print means Reducing your Carbon Print I don’t eat Greens!
“Plug It In” Engine Block Heaters & Timers and More Ideas for the Home Plug in when temperatures drop below 20 0 F. Use timers to activate heaters two hours before starting. Reduces air pollution and excessive engine wear.
At work Read UAA’s Energy Policy Read UAA’s Energy Policy Buy Energy Star Buy Energy Star Green Purchasing Green Purchasing Zero – Waste! Zero – Waste! “Recycle or Bust” “Recycle or Bust” Reduce travel Reduce travel I’m working too!

At the Fridge Eat less meat Eat less meat Buy local – buy organic Buy local – buy organic Buy seasonal Buy seasonal Don’t waste food Don’t waste food Experiment with your Eco Footprint Model Experiment with your Eco Footprint Model less Meat?
Zipping around Bike – walk Bike – walk Car / van pool Car / van pool Emissions ~ MPG Emissions ~ MPG What about flying? What about flying? Bike to Work Day May 21 4xPaw Power!
What if? Commuting Data – 18 Thousand Metric Tons of CO2 Commuting Data – 18 Thousand Metric Tons of CO2 One less trip to campus / week: One less trip to campus / week: - Avoided: Six Moon Commutes - Carbon Footprint Reduction: 7%
U-Pass Free Rides Seawolf Shuttle Free & Dependable Transportation Services and Alternatives Hiking Across Campus
Going Carbon Neutral Neutral is good if only I knew what that means! Neutral is good if only I knew what that means! Simple – making or buying offsets Simple – making or buying offsets TerraPass, STI, …. TerraPass, STI, …. Tax Credits Tax Credits Corporations – Gov’t already moving Neutral Corporations – Gov’t already moving Neutral Seems Simple!
Air Travel – HUGE Footprint Carbon Offset – Easy!
Just in case you Forgot! Vote!!! Vote!!! Voters taste better too!
So, …, does UAA have footprint? 45 thousand metric tons! 45 thousand metric tons! Metric ton??
