Incentives are good but you still have to watch out for greenwashing lies. If you take a look at carbon credits for instance there is an incentive to plant trees but what happens in reality is quite different; the industry is full of frauds such as not planting out forests that are on someones books. Sure you can use cardboard for a a lot of things but liquids and pressurized goods like soda are difficult. I don't think there is a way to have a biodegradable coke bottle. We need go to standard sizes of glass or s/s packaging. It will require infrastructure and it will cost some money which of course the companies won't like.
