Higher taxes and a controversial limit on virgin plastic production are among a set of policies that could slash the amount of plastic waste leaking into the environment, a new study has found.

Researchers used artificial intelligence to pinpoint four new policies they say could reduce the amount of “mismanaged” plastic waste -- more likely to leak into the environment -- by over 90 percent by 2050.

The University of California scientists hope their findings will inform negotiations to agree the world’s first treaty on plastic pollution that began Monday in Busan.

The policies are: investment into waste-management infrastructure, limits on virgin plastic production, financial measures such as a packaging tax, and mandating that new products contain at least 40 percent recycled plastic.

They are “by no means a panacea” to the huge problem of plastic pollution, cautioned Neil Nathan of the University of California, Santa Barbara.

But when implemented together, the measures could reduce annual levels of mismanaged plastic waste to around 11 million metric tons by 2050, compared with 121 million under a business-as-usual projection.
