The graph below depicts the marginal benefit curves $$(\mathrm{MB})$$ to nations $$\mathrm{A}$$ and $$\mathrm{B}$$ of reducing $${\mathrm{CO}}_2$$ emissions. The reduction of $${\mathrm{CO}}_2$$ emissions is a public good. The marginal cost (MC) to nation $$A$$ of reducing emissions is also shown. Assume for simplicity that only nation $$A$$ is capable of reducing emissions. S (m) If nation $$\mathrm{A}$$ is deciding unilaterally, how many tons of $${\mathrm{CO}}_2$$ would we expect it to reduce? 35000 tons 45000 tons 15000 tons 5000 tons
