This study aims investigating the relationship between CO2 emissions, renewable energy consumption, economic growth, and population density in G7 countries for 1991–2009 period. In this study, Levin, Lin and Chu; Breitung; Im, Pesaran and Shin; ADF- Fisher Chi-square; ADF- Choi Z-stat; PP- Fisher Chi-square and PP- Choi Z-stat panel unit root tests, Johansen-Fisher panel cointegration test, panel Granger causality test, impulse-response test and Panel OLS, fixed effects, random effects tests were employed. As a result of the study we can say that from country to country the relationship between our variables may show difference, but ultimately we have presented evidence that economic growth, renewable energy consumption and population density are the causes of CO2 emissions
