Carbon Calculators
Calculating (and Maybe Offsetting) Your Carbon
One of the best things you can do is calculate your carbon emissions. It really rams home how much carbon one can generate with particular activities, at home, traveling, etc… Then you can learn to avoid that behavior. (And there are so many examples being put into this blog of what you can replace that behavior with!) And that is why I threw my full weight behind using carbon calculators to learn how to avoid certain behaviors. I certainly learned how to avoid flying when I found out that one set of trips over the fall of 2017 wiped out 25 years of my being vegetarian. Aie. I now take the train as much as possible.
There is also what is called “offsetting” of trips. Offsetting is where you can make a donation to a climate-fighting nonprofit to “offset” that carbon emissions you just generated. However, when you give money to an organization, there is always loss of money for overhead, other administration, etc. – and there is no guarantee that the money will wind up where it really needs to go. Further, buying offsets puts all the pressure on our wallet – and not on the airline or car manufacturer/company that we are using. Yes – we are the one making the trip, but they have a large part in generating carbon emissions by encouraging the use of fossil fuels, etc. By encouraging us to buy offsets, they don’t have as much of an incentive to fix the airplane doing the polluting,” Geiling, 2014, Smithsonian Magazine:
“By offering offsets, airlines can appear eco-friendly without taking robust steps to actually reduce their emissions.”
It is far better to avoid the carbon generation in the first place. See our Transportation/Travel page for ideas on decreasing carbon emissions.
However, offset as the LAST RESORT – and if offsetting, please donate the equivalent cost of that C02 (or more than) to a cause that prevents C02 output or that sequesters it. Here is a nice article by the Natural Resources Defense Council on what to consider when you buy carbon offsets: https://www.nrdc.org/stories/should-you-buy-carbon-offsets. Two key points include: 1) they should be third-party certified (all ones mentioned here are); 2) the action should be permanent; and 3) the action should be in addition to something that would have been done anyway. (Geiling, N. 2014, NRDC, Smithsonian Magazine).

So far, I think Native Energy is the best (has mapping tools) for those of us in the US, but we’ll see; it seems to be generating higher carbon numbers than the others, thus requiring more money for offsetting. It will be important to research their calculations.
