This document summarizes a regression analysis of global carbon dioxide (CO2) emissions from 2017 to 2020. The analysis identified key factors influencing CO2 emissions, including energy consumption, vehicle production, population, and GDP. Energy consumption and vehicle production had the strongest correlations with CO2 emissions. Regression models for each year found energy consumption and vehicle production were significant predictors of CO2 emissions, while the relationship between GDP and emissions was inverse. The analysis suggests promoting renewable energy and green transportation options to reduce CO2 emissions.
