That's pretty false on it's face. Some building products, like cellulose insulation and cork are actually carbon negative.
Even among carbon positive products, some are much less CO2 intensive over their lifetimes than others. EVs have far lower lifetime emissions than ICEs even if they have slightly higher embodied CO2 of production [1], and EVs can be dispatched to only charge using renewables, thereby reducing lifetime emissions even more.

- Alupis 4y agoHow do you think cork, using one of your examples, is processed into building materials and transported to the construction site? Hint, it's not carbon neutral.
- danans 4y agoUnless you grow, raise, or hunt all your food under your own physical power, eating isn't carbon neutral either. And doing that isn't scalable anyways. We are going to build no matter what, just like we are going to eat. It's pointless to argue that nothing is carbon neutral when some ways of living have significantly lower carbon intensity than others. Therefore it makes sense (assuming one takes climate change seriously) to go about our lives in the least carbon intensive ways that are possible for us economically. So for someone who it works for practically, an EV can result in much lower lifetime CO2 emissions than an ICE, and using cork or similarly low CO2 insulation can result in lower lifetime CO2 than using fiberglass.
