The second law of thermodynamics states that it's impossible to develop an engine operating in a cycle that will produce no effect other than transfers of heat from colder body to the hotter body.

The effect is the 'heat lost or external work done' to make operate such a system in the cycle. This will lead to pollution as energy is being wasted.
