Lead

A gray-white metal that is soft, malleable, ductile and resistant to corrosion. Sources of lead resulting in concentrations in the air include industrial sources and crustal weathering of soils followed by fugitive dust emissions. Health effects from exposure to lead include brain and kidney damage and learning disabilities. Lead is the only substance which is currently listed as both a criteria air pollutant and a toxic air contaminant.

Leakage

A reduction in emissions of greenhouse gases within the state that is offset by an increase in emissions of greenhouse gases outside the state.

Low Carbon Fuels Standard (LCFS)

LCFS is a discreet early action measure of the Global Warming Solutions Act of 2006. This regulation reduces the carbon intensity (greenhouse gas emissions per unit of energy in the fuel) of transportation fuels by 10 percent by 2020.

Acronyms:
LCFS
Low Emission Vehicle (LEV)

A vehicle that meets the ARB's low emission vehicle standards. For more information, please go to our low emission vehicle website.

Acronyms:
LEV
Low Emission Vehicle II (LEV II)

California exhaust emission standards for 2004 and subsequent model passenger cars, light-duty trucks and medium-duty vehicles. Find more information at "Drive Clean."

Acronyms:
LEV II
Low NOx Burners

One of several combustion technologies used to reduce emissions of nitrogen oxides.

Lowest Achievable Emission Rate (LAER)

Under the Clean Air Act, the rate of emissions that reflects, the most stringent emission limitation in the State Implementation Plan of any state for a given source unless the owner or operator demonstrates such limitations are not achievable; or, the most stringent emissions limitation achieved in practice, whichever is more stringent.

Acronyms:
LAER
Lubricity

A measure of the ability of an oil or other compound to lubricate (reduce friction) between two surfaces in contact.
