Some quick digging regarding proportion of use of crude for energy vs chemical products: "This demand for chemical products has a direct impact on energy demand (and consequently CO2 emissions). The sector accounts for approximately 11% and 8% respectively of the global primary demand for oil and natural gas." https://www.iea.org/newsroom/news/2018/june/commentary-from-energy-to-chemicals.html https://www.iea.org/newsroom/news/2018/june/commentary-from-... So my 99% and 95% estimate was way off, if I'm reading this correctly - which I may not, as it seems to be referring to energy used to create chemical products, not necessarily the proportion of oil used as chemical precursors. Best I can find though.
