This paper analyzes the relationship between foreign investment and carbon dioxide (CO2) emissions in China during the past 30 years. It uses FDI stock to explain CO2 emissions at aggregate and industrial levels. No significant result is found at aggregate level but a few significant results are found in some relative energy-consuming industries. This paper also uses the Granger causality test to find if there is relationship between FDI inflow and CO2 emissions and no causality is found.
