In 2014, Chile adopted a carbon tax as part of a larger tax reform (Law 20780), which included changes to other taxes. The carbon tax targets plants with boilers and turbines whose emission sources sum 50MW or more of nominal thermal power generation (emissions from biomass are exempt). The tax rate was set at $5 US/ton CO2e in 2017. See the case study appendix of PMR’s 2017 Carbon Tax Guide for a survey.
