Australia is one of the largest nations in the globe in terms of land area and is home to numerous animals alongside unique and unusual climates and immense forests and oceans. Despite having a very tiny population, the nation is an extremely valuable ecological territory. Unfortunately, due to several changes in land use, habitat loss and deterioration-particularly in light of the recent severe bush fires exacerbated by climate change-the environmental issues in Australia have got the attention of many academics. Therefore, this paper seeks to assess the association between Australia's energy use, [Formula: see text] emission, trade liberalization, industrialization and economic growth from 1990 to 2018. An autoregressive distributed lag and a vector error correction model (VECM) are employed to take care of possible endogeneity and the long-run association. Our results demonstrated that economic growth and energy use have positive and statistically significant effects on emissions of [Formula: see text], but trade liberalization has a significantly adverse influence on emissions of [Formula: see text] both in the long and short term. Granger test in VECM uncovered single-direction Granger interrelationships among trade liberalization and industrialization, as well as among industrialization and carbon dioxide. When attempting to implement effective energy policies, Australian policymakers should first take into account the prominent role played by energy usage and trade liberalization in promoting economic development and impeding environmental health.
