The two tobacco companies Altria and Philip Morris International combined made up 2% of the branded plastic litter found, both Danone and Nestlé each produced 3% of it, PepsiCo was responsible for 5% of the discarded packaging, and 11% of branded plastic waste could be traced to the Coca-Cola company.
This seems to me like a self-fulfilling prophecy. Of course the biggest companies with the most easily identifiable packaging are going to be the ones identified in this study. The majority of the plastic, however, is not, and it’s difficult to tell who produced it.
The article addresses this as well, mentioning that this is the reason we need traceability, so we can get the true metrics on who is creating and thus responsible for the bulk of plastic waste.
The big players like Coke and others are obviously very much responsible for a big part of the problem. I just didn’t see people mentioning this part of the study in the comments, so I wanted to bring it up.
