    Look at the referenced pdf:

    Petcoke has higher carbon content than coal. Different quality coals have different carbon content levels and different energy yields. The two most common types of coal are bituminous and sub-bituminous. Using a median figure for these two coal types we find that petcoke emits 53.6 percent more CO 2 per ton than coal and 7.2 percent more CO 2 per unit of energy. So when a coal plant co-fires petcoke it emits more CO 2 than firing coal alone.
    See Table 1 for estimated values.

    Others have simply gotten old. I prefer to think I've been tempered by time.
