In this research well-known machine learning algorithm Extreme Learning Machine, ELM, is used to investigate the relationship between CO2 emission and energy intensity for countries in OECD. The results indicate a strong correlation and the method perform well for estimation.enExtreme Learning Machine (ELM)Energy IntensityCO2 emissionArticle69168752618-6462
