Greenwashing should be seen as a positive sign that companies are moving in the right direction, according to the founder of British energy firm Ecotricity.
"But you know, I take it as a good thing.
People say to me, 'oh, there's greenwashing, it's a bad thing'."
"And I say, do you know what, it's not a bad thing because 10 years ago, these companies that are greenwashing today, didn't care, right?"
I say that's progress.
