Abstract: This paper investigates the environment tax and trade liberalization with different market structures (pure oligopoly or mixed oligopoly) juxtaposing the substitutability of the goods (homogenous goods and differentiated goods), wherein environmental damage is associated with consumption. It shows that the environmental tax in mixed oligopoly is higher than in pure oligopoly irrespective of the properties of goods. In addition, it demonstrates that when the domestic market increases its openings, the tariff reduction does not always bring positive effects on the environment in mixed oligopoly but, in pure oligopoly with homogeneous goods, the tariff reduction is bad for the environment.
