Environmental/Energy/Sustainability positions within UPS

Couple of things to ask:
Firstly, can anyone tell me if UPS have any dedicated employees/staff who are responsible for keeping the companies energy/water/material use down? I'm guessing that such a position would maybe come under the jurisdiction of plant and equipment etc. Just wanted to know whether there are any positions covering this aspect of the company.

Secondly, can anyone provide me with any information relating to the UPS supervisor position which is responsible for nightly routing of vehicles and packages using UPS proprietary software?

Thanks
