What a great idea for an assignment! Looks like it was an eye-opening exercise for everyone. Another interesting exercise would be to get multiple students to research the upfront carbon of the same thing and then see how consistent, or inconsistent, their results are. Being a relatively new form of science with limited sources of information, it seems like there is still a lot of room for interpretation on how you calculate your numbers. Mass timber is one example I can think of in the building industry which is my area of practice.
As a "semi-retired" OK still working conservation ecologist ... I always wonder about the costs related to irrevocable habitat destruction and direct loss of species from all of these issues. Yes, would add another layer of complexity for sure in the analyses.
One critical issue in my military studies over the years has involved the question of varied maintenance demands for comparable pieces of equipment, I.e. how many hours must that aircraft spend being serviced and maintained as compared to a similar but different aircraft? Sometimes the difference is substantial and can be a deciding factor in a procurement choices. But also it often turns out that more experience with an aircraft or vehicle shows that the maintenance burden can be reduced as mechanics get experience or improve techniques. So should considerations of after purchase care be factored in for clothing, or machines?
Isn't obsessing over a cookie's CO2 just a bit much? Especially as China is:
"Throughout 2022, China granted permits for 106 gigawatts of capacity across 82 sites, quadruple the capacity approved in 2021 and equal to starting two large coal power plants each week, said the report.
Last year, China experienced its worst heat wave and drought in six decades, dealing a blow to hydropower-reliant provinces -— and prompting authorities to turn toward coal instead.
To ease the power crunch, coal plants boosted their output, with daily thermal coal consumption hitting a record high in August." (CNN)
And 2023 will exceed that planned/build coal fired plants.
NPR ""Everybody else is moving away from coal and China seems to be stepping on the gas," she says. "We saw that China has six times as much plants starting construction as the rest of the world combined."
And you all are worried about the West's making T-shirts to wear and cookies to eat?
Eyes being averted on purpose on the REAL problem here? Toss in India as well. This is just an exercise in self-flagellation.

Do you offer this class online (or any other class)?
