The article is about total green footprint, focused on where the battery is manufactured and the power source for that manufacturing (coal, hydro, nuclear, etc.) Plus the power source of the electricity used for charging.

Executive Summary: It may take years for an EV to overcome it's starting deficit compared to an ICE/diesel depending on where the battery was manufactured.

Just to build each car battery—weighing upwards of 500 kilograms (1,100 pounds) in size for sport-utility vehicles—would emit up to 74 percent more C02 than producing an efficient conventional car
...depending on where its made (heavily coal-powered or not)

“It will come down to where is the battery made, how is it made, and even where do we get our electric power from,” said Henrik Fisker, chief executive officer and chairman of Fisker Inc
It could take a Leaf 3 years to break even with a gas guzzler according to the article.

NorthVolt AB CEO Peter Carlsson, a former Tesla manager who is trying to build a 4-billion-euro ($4.6 billion) battery plant in Sweden that would run on hydropower, said “Electric cars will be better in every way, but of course, when batteries are made in a coal-based electricity system it will take longer” to surpass diesel engines

"Coal is King in South Korea", followed by nat gas and nuke. Here, my Bolt runs on mostly nat gas and a little bit of wind.

Yet another "ICE is cleaner" article that doesn't take into account the continuous improvement in cleaning up power plant emissions. It does point out a major issue about EVs - batteries made in countries that don't like the US - without actually addressing it.

This article also assumes the ICE engine will be maintained. ICE engines that aren't maintained will create increasing amounts of tailpipe emissions as they age.

Did the German consultants, Berylls, factor in cheating on ICE emissions tests?

Many of you are focusing on the tailpipe emissions of an ICE engine, or the fact that you get your charge from solar, etc. And while that may not be insignificant, the main focus of the article was on the environmental cost to produce the batteries in the first place.

The article is claiming that the current CO2 released by battery manufacturing is causing EVs to be dirtier than ICE/Diesel cars while at the same time ignoring the operational issues with ICE, and more specificially diesel vehicles.

It doesn't ignore that at all. That's baked into their calculation of the return.

The article makes an assumption that the ICE engine's emissions performance doesn't change over time. The reality is that even a properly maintained ICE engine will slowly emit more as it ages. An improperly maintained ICE engine can emit a lot more after even two or three years. Therefore one of the base assumptions the study made is invalid - the CO2 cross point is very likely two or three years earlier than that study reports, and in fact, I suspect it's somewhere between the 7 and 8 year point based on the emissions warranty required by US Law.

I smell Koch brothers stench in the funded misleading article.

The total amount of energy spent on making the ICE Cars should be compared with the total amount of energy spent on making EV and its batteries and this can be done using cradle to grave Life Cycle Analysis. Anything else that Bloomberg publishes if it doesn't involve life cycle analyses are crap, funded by the Koch Brothers.

As for the operational day to day use of the vehicles, consider that it takes 4-6 kWH of dirty electricity to produce a gallon of diesel or gas from oil. The same amount of electricity can move an electric car the same distance as a gallon of comparable performance ICE car. Have they conveniently omitted this source of additional CO2 from electricity for the ICE cars?

And when the ICE needed oil change, that is another waste thing to mind, and it's carbon count as well, plus the amount of energy needed to treat or process the waste oil.

It's 4-6kWh of _energy_. Not electricity.
