Yes, I'm done in 30 seconds.
Two slides following the Newton slide, the Porter hypothesis is discussed in context. I would argue that the idea has been around for a century and a half. There is no evidence for it. Government has never been able to force business to become greener by designing good regulations.
What I would suggest instead, if you want to promote greener practices, is to eliminate market distortions. Look at the way business was spontaneously prodded to become greener in the past and so give no subsidies; hold them responsible for their actions but let them be free to innovate; and don't consider the Porter hypothesis and the precautionary principles as policy guidelines.
