Addressing climate change and its environmental impact is one of the greatest challenges of modern life. In fact, most of today’s sustainable strategies are essentially related to the intent of reducing overall carbon dioxide emissions, which is subsystem of carbon footprint. According to the Paris Agreement, which was signed in 2015 and entered into force in 2016, to reduce climate change, countries aim to balance the greenhouse gases released and captured until 2050. Thus, this study aims to measure the performance of selected countries based on carbon emissions in 2050. To measure performance, the Data Envelopment Analysis (DEA) method is used. In order to use this method, decision-making units (DMUs), inputs and outputs are determined. DMUs are selected from the countries that signed the Paris Agreement. Input is identified as Primary Energy Consumption. Outputs are selected as Gross Domestic Product (GDP), Carbondioxide Emission (CO2), Nitrous Oxide (N2O). The countries’ primary energy consumption and total CO2 emission data are available between 1980 and 2019. The countries’ GDP and total N2O data are available between 1990 and 2019. For each selected country, these data are fore-casted in R Studio using the Arima method with a 95% confidence interval until 2050. Performance measurements are conducted across South America.
