Yes. I entirely agree with Mr. Boswell's comments and recommendations.
I think as soon as you're making an environmental claim about a company, a brand, an activity or a scientific fact more generally in order to promote a business interest, irrespective of where it is, there should be a substantiation requirement. You should be required by law to do a test to come up with evidence. Then, in addition to that, ideally you should also be required to disclose this evidence to the public, thereby ensuring that, in that type of environment, you're not just making environmental claims out of the blue without proper evidence.
