In the context of the Draft Policy on open standards, here's one
example of why multiple standards can lead to chaos.
Multiple Standards Confound Power-Supply Designers

“green” label. But how much difference really exists between them?

What's a poor power-supply designer to do? The U.S. alone has four

Then there's the Australia Greenhouse Office (Australia also
participates in Energy Star), the China Energy Conservation Project,

programs, but there are enough differences to make powering a product
for a global market an exercise in anxiety.
Fortunately, many of the programs are voluntary. Therefore, you could

of efficiency specs. But you won't get the compliance sticker, which
would mean mean you'd most likely be positioning your brand as a
"value leader" while sacrificing your profit margin.
A better approach would be to familiarize yourself with the programs
out there, go to the key Web sites to get the latest updates, and then
design your product to meet as many energy-friendly label criteria as
practical. This should help you get yourself onto the most popular
energy-program Web sites—and position your product among the green
