Is there a serious source ranking all global CO2 emissions? Where percentages add up to 100%?
Our World in Data is usually my go to for reliable data:
Cement is the source of 8% of the world's CO2 emissions (2018)

#52Very 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...
Statistics on how much CO2 something emits can vary wildly. For instance, meat consumption has high CO2 emissions when you include the CO2 emitted by transporting grain to feed animals. But most typical studies would include that under emissions due to transportation. Hence why you can have some studies claiming meat accounts for a double-digit percentage of emissions while others claim that all agriculture contribut…
About meat specifically -- one has to be careful when counting all greenhouse gases versus just CO2, and pure quantity of gas vs. effect on global warming.
Cattle produces a lot of methane, which has a very powerful greenhouse effect, a lot more powerful than CO2. So while it does not contribute to CO2 emissions that much, it contributes to the greenhouse effect proportionally a lot more.

#53I’ve been touting this fact for years. 90% of landfill debris is from demolition. We need more renovation instead of new construction.
"About 13 percent of the solid waste in Missouri landfills is demolition waste." From page 128 of https://dnr.mo.gov/env/swmp/docs/wcs98constructionwaste.pdf
Debris is a type of solid waste.

Do you have a source for this?
“Demolition represents more than 90 percent of total C&D debris generation, while construction represents less than 10 percent.“

I’ve always wondered how much standardisation there is in reporting these types of numbers, particularly with regard to countries, albeit not enough to actually look in to it. Say Australia digs up some coal, ships it to China, it’s used to power factories and smelters to produce goods, then those goods are shipped to and used by Americans. Is there consensus on who the pollution from burning coal gets tied to? Or do…
It gets tied to China, for better or worse.

CO2e is standard when talking about GHG which takes this into account.

#57Crazy that quarrying and transport is less than 10% of the CO2 from Concrete.

#58By the way, the bridge is part of the Brennerautobahn between South Tyrol in Italy and Innsbruck in Austria. The exact bridge is located in Italy.

It goes to China, because it is the one that can change it. But that's when you're looking at the output of countries. What you could also do is look at the output of individual persons, and then you could more easily attribute the CO2 to the American.
Sustainable energy without the hot air does this, it's a great book though I've heard it's somewhat outdated now.

90% of construction and demolition debris is from demolition.
Not quite the same as your opener that claimed that it's 90% of all debris.
