Mexican Emissions Trading System (pilot program)
Mexico's ETS began a pilot program in January 2020 with free allocation and no monetary sanctions. Rules for the operational phase have not been published, so the pilot rules remain in force; the environment ministry (Semarnat) said in September 2026 that it would issue definitive rules by early 2027.
