I think it was because we all support providing information for consumers. By doing it on a voluntary basis and a self-regulated basis, you then have the flexibility. For example, the labels are too small, and by putting an extra label on you may need more packaging, which we don't want, or extra costs. Then we might leave some information off. If it were regulated, we'd have to put it on come what may, and at the end of the day, it may not be the best thing for the consumer.
For us, voluntary is more flexible, but it needs to have certain standards within it. I'm pleased that the companies that are using the same scheme are using all the same standards so that we don't confuse consumers further.
