Carbon Calculators and Net Zero Houses

“The logic of net zero is marketing psychology. I have talked to people who reason that the PV array should be three times the size of what you need for net zero, because about 1/3 of the energy you use is for transportation and 1/3 is embodied in the stuff you buy, and you should make up for that as well in order to be completely righteous.”

Bingo

And don’t forget about…

The book: The Consumer’s Guide to Effective Environmental Choices: Practical Advice from the Union of Concerned Scientists breaks it down into

1. Global Warming / greenhouse gases
2. Air pollution (common and toxic sub-categories)
3. Water pollution (common and toxic sub-categories)
4. Habitat alteration (water use and land use sub-categories)

And then shows you in a average US household how different types of expenditures impact each of these categories. It’s a pretty easy thing to figure out that essentially one just has to “follow the money”. So it’s the big things like: food (meat and dairy primarily), transportation, and household operations that are the environmental bad guys.

So… what are you waiting for! Just sit there!
