LCA for Fossil Fuel Product vs Battery Product?

https://www.cibsejournal.com/technical/the-meaning-of-life/ This is a CIBSE study, and multiple others have similar conclusions.   Pending on the refrigerant and leakage numbers, using heat pump is not always a positive, especially with current 410A.  Good news is 410A phase out date is 2025.  

Another example comparing battery electric to internal combustion vehicles - https://www.sciencedirect.com/science/article/pii/S2452321618301690 The break-even graphs in this paper are a little hard to wrap your head around but, once you do, super interesting!

Not only is R410A (GWP 2088) being phased out, new refrigrerants are available today with great performance and low GWP. We're using R1233zd (GWP 1--that's right, 1) in our new 400k sf tower for Georgia Tech.

I don't think this is exactly what you are looking for, but I'm a fan of this paper from the Union of Concerned Scientists. It includes references. https://www.ucsusa.org/sites/default/files/2020-05/evs-cleaner-than-gasoline.pdf I also love the chart on this article (just keep scrolling): https://www.distilled.earth/p/a-fossil-fuel-economy-requires-535x Kristian Kicinski AIA, LFA, LEED AP BD+C (he, him) Associate Principal / Director of Sustainability direct: 206.536.1370 Send me files

This video does a good job in a few minutes breaking down the problem, explaining the assumptions, calculations, and results. cites references etc. Over the past 5 years the US electric grid has gotten cleaner, so the numbers for battery products have improved. The video may be useful for skeptics. Are Electric Cars Greener Than Gasoline Powered Cars? https://youtu.be/6RhtiPefVzM?si=PgzgiJXL7DMxURNF Electric cars are touted as a solution for reducing emissions and improving the environmental impacts of transportation, but are electric cars actually any better for the environment than gasoline cars? This video looks to answer three main questions: 1) Doesn't EV battery production cause a lot of emissions? 2) Don't electric cars get their power from fossil fuels? 3) Isn't lithium mining terrible for the environment?
