I think people often underestimate the power of consumers. But I equally say that consumers are like shock troops: You can't keep them agitated and motivated and committed and active forever. There are pulses where they switch on to a particular issue, and just inevitably they switch off.

I'm worried about greenwashing. I think we should come down on it very, very hard, whether it's with criminal intent or actively deceptive.

Companies watch what consumers are doing like a hawk.
