One of the most pressing global environmental challenges is avoiding plastics pollution—especially in oceans, where plastics are causing considerable ecological damage. A focus on mitigating plastics pollution has led to new policies in the United States and other developed nations aimed at reducing plastics consumption, with notable prohibitions on straws and bags. But while prohibitions on visible and commonplace plastic use have become increasingly popular, there has been little analysis as to their effectiveness in addressing plastics pollution.
An analytical approach to the issue demonstrates that commonly debated or promoted policies, such as plastic straw bans, are unlikely to have any meaningful impact on mitigating the worsening problem of ocean plastics pollution. Rather, policy focused on improving waste management—especially in countries that contribute primarily to plastics pollution—is far more likely to reduce plastic leakage into the environment.
