To be more specific I'm actually interested in finding all possible ads around sustainability and zero waste. Not necessarily for specific companies.
I am writing FB ads for my clients and would like to get the grasp of how others did it. I have some experience writing for some more pricy two-day seminars or online courses where I could touch on some deeper problem but this is "just" a canvas bag. Many eco-warriors already have such bag.
Hope you can enlighten me a bit on that one.
