The economist inside me says it would be better to tax disposable plastic. The tax could cover the cost to clean up the litter. That would create jobs in three ways: 1) plastic clean-up jobs, 2) businesses and economic activity that desperately need disposable plastic can still possibly survive, and ) jobs making disposable plastic. Anyways, it's a lot better than taxing things we all agree we want more of. Like jobs…
Local governments in India (mostly all of them) tax disposable plastic already.
One of my favourite examples of this concept is marijuana laws in Colorado. 1 BB in gov rev, 200 MM in tax rev alone. Less spent on law enforcement. Less crime due to a black market. Less innocents in jail that are spending tax dollars instead of producing them. Everyone wins except the DEA and prison system.
