From DDL Wiki
Following regulations are California state laws regarding environmental regulations for vehicle.

CARB ZEV Program
The California ZEV program (ZEV) program is a program initiated by the Californian government to promote the zero emission vehicles.
Alternative Fuel Tax
The following table shows excise tax imposed on compress natural gas (CNG), liquefied natural gas (LNG) and liquefied petroleum gas (LPG) as vehicle fuels can be paid through an annual flat-fee rate sticker tax based on vehicle weight.
| Unladen Weight | Fee |
|---|---|
| All passenger cars and other vehicles 2,000 lbs or less | $36 |
| More than 4,000 lbs. but less than 8,001 lbs. | $72 |
| More than 8,000 lbs. but less than 12,001 lbs. | $120 |
| 12,001 lbs. or more | $168 |
The excise tax on CNG, LNG and LPG that owners and operators may pay are $0.07 per cubic feet, $0.06 per gallon and LPG of $0.06 per gallon. Excise taxes on ethanol and methanol containing less than 15% gasoline or diesel fuel are reduced to $0.09 per gallon.
Emission Reduction Requirements
A public transit bus rule adopted by the California Air Resources Board (CARB) regulates public transit fleets and sets emission reduction standards for new urban transit buses. The rule allows transit fleets to choose one of two options in order to reduce their emissions to the required levels: using alternative fuels or clean diesel. A solid waste collection vehicle (SWCV) rule adopted by CARB regulates SWCV weighing 14,000 pounds or more, run on diesel fuel, have engines in model years from 1960 through 2006, and collect waste for a fee. Each year through 2010, waste companies are required to install Best Available Control Technology devices or purchase vehicles that run on compressed or liquefied natural gas, in order to reduce the diesel smoke coming from some of their waste collection trucks.

Calculation
Gasoline vehicle
Greenhouse gas emissions are measured CO2-equivalent grams per mile average using twp EPA drive cycles, "FTP" and "highway" test cycles (40 CFR, Part 86, Subpart B). The formulation is:
CO2-Equivalent Value = CO2 + 296 x N2O + 23 x CH4 - A/C Direct Emissions Allowance - A/C Indirect Emissions Allowance where A/C Direct Emissions Allowance = A – (B x C) A = 9 * CO2- equivalent grams per mile B = 9 * CO2 - equivalent g/mi * (GWP of refrigerant)/1300 C = 1, except for low-leak A/C system where C=1-(0.12*credit) where credit = 3.0*CO2-equivalent grams per mile
Alternative fuel vehicle
CO2-Equivalent Value = (CO2 + A/C Indirect Emissions) x (Fuel Adjustment Factor) + 296 x N2O + 23 x CH4 + A/C Direct Emissions
Alternative Fuel Vehicle (AFV) Acquisition Requirements
On and after January 1, 2006, when awarding a vehicle procurement contract, every city, county and special district, including a school district and a community college district, is authorized to require that 75% of the passenger cars and/or light-duty trucks acquired be energy-efficient vehicles. Vehicle procurement contracts are also authorized to evaluate fuel economy and life cycle factors. By definition, this includes hybrid vehicles or alternative fuel vehicles that meets California's advanced technology partial zero-emission vehicle (AT PZEV) standard for criteria pollutant emissions.
