ZEV requirement increases from 4.5% in 2018, to 22% by 2025, at @ ~12 minutes.
First, understand that any percent is based in ZEV credits, not cars (see explanation below).
While the data has likely changed from previous data, the ZEV requirement ALSO includes non-ZEV cars. For instance, for 2012-2014 "Phase 3", 12% of the production of the six Large Vehicle Manufacturers had to meet yearly ZEV requirements (including ZEV's, Enhanced AT PZEVs, ATPZEVs and PZEVs). Of that 12%, 0.79% must be ZEV.
CARB equirements from 2012-2014
Model year ---- ZEV Credit % of total annual sales
2012 ------------ 0.79%
2018 ------------ 2.00%
2019 ------------ 4.00%
2020 ------------ 6.00%
2021 ------------ 8.00%
2022 ----------- 10.00%
2023 ----------- 12.00%
2024 ----------- 14.00%
2025 ----------- 16.00%
Here is how the world's largest auto manufacturer complied with CARB-ZEV then. The "big six" Large Vehicle Manufacturers (LVM) auto manufacturers of the world (Toyota, Honda, Nissan, GM, Ford, Fiat/Chrysler) were required to begin the modern day CARB-ZEV rules, starting in 2012. Toyota did with Rav4 EV primarily (there were also less than 100 Scion iQ EVs).
Over three model years, Toyota sells about 900,000 Toyota cars in California.
The 0.79% ZEV credit rule (model years 2012-2014) for Zero Emission Vehicle (ZEV) sales means that Toyota must earn 7,110 of the ZEV credits over three model years (0.79% * 900,000). Each Toyota Rav4 EV sold in California earns 3 of the ZEV credits each, so 2370 battery electric cars solve that over the three model years. Toyota actually built 2538, and discontinued the vehicle right on schedule.
For model years 2015-2017, the Toyota Murai hydrogen car earns 9 credits per car, therefore Toyota need only make 790 individual sales over three model years, or 263 per each model year during 2015 - 2017.
Should the 9 credits for hydrogen cars be retained past 2017 (they are scheduled to disappear in 2018), then Toyota would only have to sell 5,333 hydrogen cars per year IN CALIFORNIA ONLY (none in the several other CARB-ZEV states) without any battery electric cars sold, even at 16% of total credits in model year 2025. Currently, the rules allow hydrogen cars to only be sold in California, while electric vehicles (EVs) must be sold in all CARB-ZEV states in 2018 and later.
Credits from 2018 on are based ENTRIRELY on vehicle range @ ~15 minutes
Refueling time should be a variable credit. Range and refueling time are important to the consumer.
THERE WILL BE NO FAST-REFUELING CREDITS STARTING IN 2018, reducing the huge subsidies Tesla and the FCEVs have received since 2012. @ ~17 minutes.
Tesla hasn't received fast refueling credit for about two years. Hydrogen cars do, however.
But the ZEV credit formula's as described there may be subject to change.
Watch the hydrogen guys squeal.
