Trade liberalization raises many concerns regarding the costs and benefits to society. One of the primary concerns when establishing the North American Free Trade Agreement (NAFTA) was environmental degradation. Some of these issues were addressed in signing the environmental side agreements. Although these agreements are relatively new, it is possible to assess the effects that have come about through creating the sister institutions of the North American Development Bank (NADBank) and the Border Environmental Cooperation Commission (BECC), as well as the Commission for Environmental Cooperation (CEC). An assessment and comparison of environmental impacts and trade agreements between the United States, Mexico, and Canada can be applied to other regional agreements, such as the Southern Common Market, known as MERCOSUR.
