The EU-Mercosur Trade Agreement is a big deal for both sides. By using a complex model, the researchers found that the agreement will lead to a small increase in CO2 emissions, but it will actually improve the emissions/GDP ratio for the EU-Mercosur region and the world. This means that everyone benefits from the agreement, especially Latin American countries. The agreement allows Mercosur countries to export products they are good at making, while the EU can focus on more complex sectors. The researchers' results are more positive than previous studies because they included factors like Foreign Direct Investment in services and government procurement, which were not considered before.
