> Heat management of these systems will become the major contributor for environmental pollution than all vehicle exhaust.
No, extra heat just radiates away into space, nothing to worry about. The problem is in the GHG emissions to generate the energy to run (and yes, cool) these systems.
> it makes sense to optimize energy consumed per processor.
Yes, absolutely. Even if you don't care about the environment, power consumption limits chip performance. Doing more work with less power is key to producing faster chips.
