6. What is a Carbon Footprint?
• Measure of the impact that you have on the
atmosphere and climate system in terms of the
amount of greenhouse gases (GHG) your actions
produce.
• Called a carbon footprint because GHGs are
commonly reported in terms of carbon dioxide
equivalents (CO2e).

7. What is a Carbon Footprint?
• Emissions Inventory
– Direct emissions from activities (gasoline, electricity, natural gas
consumed)
• Carbon Footprint
– Includes direct and indirect emissions (all of your activities)
• Environmental / Ecological Footprint
– Includes impacts of activities on other environmental factors
(wildlife, water use, water quality, waste, etc.)
• Life Cycle Assessment (LCA)
– Comprehensive look entire product process, cradle-to-grave.
Attempts to avoid unintended consequences.

8. Why is it important?
• CO2 emissions growing rapidly.
• Scientific consensus that rising levels of CO2 cause
warming of planet, resulting in sea level rise and
changing climate conditions, affecting:
– Food supplies
– Infectious diseases
– Human habitats
• Potential for perceived localized benefits (e.g., warmer
winters) outweighed by overall negative effects (e.g.,
loss of productive crop land to drought and rising sea
levels).

9. Collateral Benefits of Action
• Climate Change is the big issue, but sustainable development practices
can help achieve other goals related to:
– Air emissions
– Stormwater runoff
– Human health
– Materials conservation
– Land and habitat conservation
– Energy efficiency (save $)
– Energy security
– Economic and community

The U.S. emits as much CO2 as Brazil, U.K., India, Russia, Canada, and South
Korea combined – and 20% of the world’s total CO2 emissions.

22. Action. What you can do.
• 1. Calculate your Carbon Footprint
Find out how to calculate your carbon footprint. Understanding your carbon emissions is the first
step to taking action to reduce your carbon footprint.
• 2. Change a Light Bulb (or two)
Electricity consumption is one of the largest components of a household's carbon footprint.
Compact fluorescent light bulbs use up to 75 percent less energy than traditional incandescent
bulbs and can last 10 times as long.
• 3. Drive Less
In the United States, a personal motor vehicle is the largest contributor to a typical household's
carbon footprint. Combining trips, carpooling, using public transportation, walking and biking all
help reduce your carbon footprint. Keep up with scheduled maintenance and properly inflate tires
to make your existing vehicle as efficient as possible when you do drive. The next time you
replace your vehicle, consider purchasing the most fuel-efficient model that meets your needs.
• 4. Reduce, Reuse, Recycle
Recycling materials requires less energy and fewer raw materials than creating a new product
from scratch. Take reusable cloth bags to the store, don't accept paper and plastic bags when you
really don't need them, and choose products that don't have excessive packaging.
• 5. Use Less Water
Pumping and heating water require large amounts of energy. Take shorter showers, install a low-
flow shower head, turn the water off while you shave or brush your teeth, and wash clothes in cold
water.

23. Action. What you can do.
• 6. Plant a Tree
Deforestation accounts for up to 20 percent of the carbon dioxide released each year worldwide.
Growing trees sequester carbon, and trees also help cool cities and reduce power consumption
for air conditioning.
• 7. Eat Lower on the Food Chain
Adopt a diet that emphasizes whole grains, fruits and vegetables and minimizes meat, seafood
and processed foods. Meat is a particular energy hog. Producing one pound of beef generates 36
pounds of carbon dioxide.
• 8. Buy Efficient Appliances
Replacing older appliances with Energy Star appliances can significantly reduce your electricity
bill and your carbon footprint. Start with the refrigerator, which uses the most electricity in an
average home.
• 9. Adjust your Thermostat
Set your thermostat two degrees higher in the summer and two degrees lower in winter to save
thousands of pounds of carbon dioxide a year. Change your furnace filter regularly and seal gaps
around windows and doors to allow your heating and cooling systems to operate more efficiently.
Note: These are estimates. Individual savings will vary based on many factors.
• 10. Spread the Word
Tell a friend about what you are doing to make a difference.
