This article seeks to generate some recommendations for the future improvement of the content of the Association Agreement (AA) between the European Union (EU) and Central America (CA). Although the political conditions for renegotiation are currently complex, it is possible to present some reflections on the provisions of the Agreement and its eventual modification, especially to strengthen synergies with the environmental and climate change commitments, such as the commitment to effectively implement the nationally determined contributions (NDCs) under the Paris Agreement of the countries of the region. The article presents recommendations for potential renegotiation on key components of the Agreement, including the preamble; objectives; exceptions; sanitary and phytosanitary measures (SPS); technical barriers to trade; investment provisions; intellectual property rights; trade and sustainable development; dispute resolution; and cooperation and political dialogue.
