This paper seeks to analyze the relationship between the environment and coal production. Coal, which is the primary energy source in China is the dirtiest of fuels (Parker 2004). The process of mining, cleaning, transporting coal to electricity generation and disposal leaves pollutants in .
percentile of the global cost curve has served as a floor for met coal pricing. Over the long run, we estimate cost inflation will add 4% annually to mining costs. This tracks an average annual 4% per year increase in met coal prices since 2006 and equates to roughly 45/metric ton in cost increases per year in today's environment.

First of all the actual mining of coal can be disrupted by both technical as weather conditions. furthermore the production costs will affect the supply. When the coals must be mined from deep within a mine the cost of extracting coal will increase and thus it may become unattractive to extract this coal.
