Grinding Tire Emission Factor
CO2 in the mining industry | ABC Dust
A large open pit copper mine can use around 200,000 L / d of diesel with an emission factor of around 2.7 kg CO2 e / L. This is equivalent to 200,000 t CO2 e / y of emissions for about 2 – 4 t CO2e / t Cu produced .

Estimating Emissions from Sources of Air Pollution
Estimating Emissions from Sources of Air Pollution. Simple emissions factors, usually an amount of emissions per time or distance for a given source, multiplied by the length of time or distance of operation to achieve over all emissions, is the first approach taken by air quality managers to estimate emissions from various types of sources.
