Recall the application about the marginal cost and marginal benefit of reducing methane emissions. what does the optimal level of methane abatement depend on?

The marginal benefit of abatement can be found like this. If the marginal benefit is $10, the optimum level is roughly 36 million metric tons. If the marginal benefit were much higher, say $150, the optimum level of abatement is about 69 million metric tons. So basically it it depends on the marginal benefit.
