The reason CARB exists

agreed.
like any political machine, you're better off with than without. the evil doers are lurking in the shadows just waiting for their chance

 

Kochs Bankroll Move to Rewrite the Constitution - EXPOSEDbyCMD

Yeah they are so mad about CARB they want to re-write the constitution

 

Complaints without suggestions don't accomplish anything.

 

I suggest we oppose a constitutional convention, I rather like that CARB can stick it to the man, even if they are also misguided in their own way.

Both cars I own would have never existed if it weren’t for carb so there is that.

 

that should read 'koch'

edit: sorry, there were two in 2017

 

Since it needs reminding, this is the reason CARB exists:

And lest anyone says otherwise, CARB has been successful in reducing things like ozone:

Depending on parameters selected you may find that ozone has not improved much since end of charts@7.

 

Link appears dead.

But surely you don't assume population has been stagnate? Even more people, same relatively good level of low smog for an extremely densely populated area.

And of course you always run up to diminishing returns. Making cars go from 30mpg to 40mpg is awesome but not nearly as awesome as going from 20mpg to 30mpg.

 

Sorry, I copied url after selecting parmeters. Should work from here

Air Quality Trend Summaries

I appreciate toaster's checking.

 

"But surely you don't assume population has been stagnate?" @9. This factor is surely important for any estimation of harm. I am not aware of any published study combining air-quality improvements in US areas with increasing numbers of lungs.

Let us hope that workers in this field are as creative as toaster, and do it.

There is probably always room for expositions on topic of fuel economy and fleet size. If only to remind folks that miles per gallon is non linear as stated @9.

 

Absolutely true, as we're probably reaching the limits of pollution control on gassers. We'll likely see significant further reductions in ozone only if the BEV/FCEV start becoming a significant % of the vehicles on the road in CA.

 

Ozone photochemistry in Calif central valley is much influenced by ag, including messy diesels. Those that are off-road vehicles are lightly regulated as I understand it.

 

Good point. That's also consistent with the inland areas of SoCal having worse ozone than the coasts:



For ozone in particular, hotter temperatures due to climate change also make it worse:
