Very interesting, didn't expect it to be that high. Another thing I came across recently : The fashion industry is responsible for 10 % of annual global carbon emissions. Source : https://www.worldbank.org/en/news/feature/2019/09/23/costo-m...
So the biggest polluters are food, clothing and shelter - I'm seeing a pattern here...
I have to wonder why we are still looking for new ways to employ Portland cement at this point, over alternatives. You can, I’m told, reduce the footprint of clinker a bit with fly ash, but you get that mostly from coal, so it’s splitting the “savings” with an equally problematic cousin, and at any rate that supply should be in steady decline now, although I guess we discovered the Tennessee Valley Authority has stockpiles of the stuff when they lost one of them a decade or two ago.
Would living in tents reduce CO2 emissions? Is that preferable?

That was my biggest take away from the Biosphere documentary, as it was the concrete used in it's construction that eventually led to the abundance of CO2 and lack of O2 in that closed system. We'll clearly have to use something else for building moon bases.

I don't have the answer, but I can imagine this is hard to compile because so many things emit CO2 all over their supply chain. So the question becomes, when do you consider something the 'final' product in the line. If it's cement, you presumably can't count 'construction' as it would be double-counted. Do you count an iPhone just during production? Or do you include shipping? If you include shipping, you can't have…
Why would it be hard to compile? Costs over supply chains are calculated all the time. And we don't have to look at IPhones, we just have to look at the subset of processes that emit non-neglible amounts of CO2 regardless of if they are the final product or not.
I’ve been touting this fact for years. 90% of landfill debris is from demolition. We need more renovation instead of new construction.

I would argue cargo ships don’t need their own category in that case since they don’t exist for any other reason than to be part of the supply chain or other goods. All cargo ship pollution can be attributed to the cargo they’re transporting.

this is a much more depressing number. steel and cement are necessary to the development of all nations, designer clothes are not.
Garments that are high quality are designed to last and be worn for a long time. High end selvedge jeans might run a couple hundred bucks, but they will last a decade. I suspect cheap, disposable clothing is driving much more emissions.
