This paper aims to assess the effect of green trade, green energy technologies, and green finance on greenhouse gas (GHG) emissions in ASEAN nations. ASEAN nations are chosen because their economies have a high capacity to mitigate their environmental impact. In addition, the evidence from these nations is highly likely to enhance the existing theoretical subsidy for sustainable practices. Using MMQR methodology, data from 2001 to 2019 have been analyzed, revealing that green trade, energy production from solar and hydropower resources, green finance, and REC significantly reduce greenhouse gas emissions. It is important to note that the empirical view of such practices from an ASEAN perspective can guide economies eager to improve the present state of the environment.
