Calculating my Household Carbon Footprint

Starting with www.carbonfootprint.com, my footprint was estimated at 21.56 metric tons of CO2, which is apparently greater than the average of 20.4 for people in the United States. Really? I hoped that we'd score a little better than this!

This site listed some things to do immediately to reduce our personal carbon emissions, but we're doing most of them, such as:

1. We turn many things off when they are not in use, but not all of them, so we can improve in this area.
2. We use the programmable thermostat, which is set to be a little less comfortable (hot or cold, depending on the season) when we are not at home.
3. We always run full dishwasher loads, which you would realize if you'd look at our counter and sink!
4. I do create a menu and go to the grocery once per week, however, I do not run all of my errands on the same day in a single trip.
5. I hang up a lot of laundry to dry, but inside of my home, not outside.
6. We use CFLs all over the house, but a search did turn up 5 more bulbs that I can replace to make us fully compliant.
7. Within the past few years, we replaced all of our appliances with energy star appliances.
8. We drink tap water, well actually, water filtered through the fridge.
9. We buy local produce as often as possible, but we have not gotten into the zone of buying local meats and poultry. The whole in season bit is a struggle during the winter, so in order to keep good nutrition, we do buy foods that are shipped. How can we avoid that during the winter?
10. We avoid "Made in China" as much as we can, and we prefer limited packaging, but do not always make it a deciding factor.
11. I recycle everything! Ask my husband!! I have been known to dive into the trash compactor after a recyclalble that my husband discard incorrectly...

So I wanted to see how another site evaluated my footprint, and here is what I found:
1. My estimated emissions are 80 tons of carbon dioxide (CO2)equivalent per year, also above the U.S. national average, at www.nature.org.
2. www.carbonfund.org provided an offset purchase calculation of 19.71 tons.
3. According to www.epa.gov our total emissions are are 57,824 lbs of CO2 per year, which is 26.7 tons, and about average for our household size in the U.S.

There were some inconsistencies in what went into the calculations, but overall, the goal is to reduce emissions, and the sites had some good advice (beyond the sale of offsets). Frankly, I did get tired after a while ... it takes some time and energy to be good steward of the planet. Haven't we done enough already? ... No?
