What we have under CEPA, I think, doesn't use the word “effects” or “regulations”. Regulations are one of many options that CEPA allows for. Whether they're used or not is sort of secondary to the act. Of course, we all want the correct effect, but having gone through many examples of voluntary reductions from various emission sources and worried that they're not actually being met in some cases, we hope that we would achieve better emission reduction through regulations.
