I'm far from a greenie, but blaming the LEDs causing the problem in this case because they're now labeled as "green" I believe is wrong.

SnwMnkys--
An observation, not a criticism. The first paragraph of your post sounds very much in line with the Brundtland Committee's
Report of the World Commission on Environment and Development: Our Common Future (available
here). Specifically, the themes addressed in part II, chapter 7, section 6 (available
here).
In my limited experience of working with traffic engineers, I am inclined to agree that, as a group, they're most interested in getting the job done efficiently and up to specification. But who writes the policies that drive the specifications? MOO, that's a central question raised by OP.
