Economic growth, carbon dioxide emissions, renewable energy and globalization

摘要

This article investigates the correlation between economic growth, carbon dioxideemissions, renewable energy and globalization for the period 1970-2010, using time series (OLS,GMM, unit root test, VEC model, and Granger causality) to Portuguese economy. OLS estimator andGMM model demonstrate that carbon dioxide emissions and renewable energy are positivelycorrelated with economic growth. The econometric models also show that the overall index of globalization has a positive effect on growth. The Granger causality reports a unidirectional causalitybetween renewable energy and economic growth.
