This study analyses the United States environmental impacts on agriculture intra-industry trade (IIT). The results indicate that there was a negative correlation between carbon dioxide emissions and intra-industry trade. According to the literature, this type of trade uses less pollution technology. We also found that emissions increase with the level of production. The economic size has a positive influence on carbon dioxide emissions.


Key words: Environment, intra-industry trade, United States, panel data.
