After the adoption of the Paris Agreement, practically all countries in Latin America submitted their Nationally Determined Contributions (NDCs) that specified their intended climate targets. Green fiscal reform would be a viable next step to move from ambition to practical implementation of these targets. Even though there are some general insights applicable to all countries, the specific national situation will determine the details of policy design and implementation. This policy brief by the T20 Climate Action and Infrastructure for Development Task Force, reviews insights provided by the academic literature and compiles expert knowledge on selected countries to shed some light on possibilities for, and limitations to, green fiscal reform in Latin America. The report is available to download on the T20 website.
