Abstract
This study examines the impact of economic development, trade openness, and energy usage on Vietnam's CO2 emissions from 1985 to 2013 by applying an Auto-regression Distributed Lag (ARDL) model. The empirical results show a long-run relationship between economic development and CO2 emissions in Vietnam that can be expressed in an inverted U-curved function. Trade liberalization exhibits a positive impact on CO2 emissions, as a 1% increase in trade openness leads to a 0.191% increase in CO2 emissions for long-run elasticity. Furthermore, trade liberalisation has lag effects on CO2 emissions, which are estimated to reverse from negative to positive after a two year period. A 1% increase in energy usage leads to a 1.391% increase in CO2 emissions for long-run elasticity. Thus, environmental quality improves with cleaner technology and stricter regulations on environmental protection incorporated into international economics at the policy level in Vietnam.
 
Keywords:Trade openness, Energy consumption, CO2 emissions, Auto-regression distributed lag model, Vietnam.
