emission factors

Emission factors are measurements used to estimate the amount of pollutants released into the air from specific activities or sources, like burning fuel or manufacturing processes. They are typically expressed as the quantity of emissions per unit of activity, such as grams of carbon dioxide per liter of gasoline burned or tons of emissions per vehicle mile. These factors help organizations and governments calculate total pollution levels, monitor environmental impacts, and develop strategies to reduce harmful emissions. Essentially, emission factors provide a standardized way to estimate and compare pollution from different sources efficiently.
