Environmentally friendly initiatives and green financing are needed to reduce pollution and transition to a low‐carbon energy system. This research was conducted to assess the efficacy of green bond financing for scaling up environmentally responsible investment in preparation for the low‐carbon energy transition in emerging Asian economies. The generalized method of moment's methodology is used to examine the impact of green finance, CO2 emission, and economic growth on the environmental investment of emerging nations over the period 2000–2021. The result showed that all these factors contribute significantly to environmental investment. In addition, the results showed that the burdens of global warming are achievable to alleviate through green bonds for the optimum transition to low‐carbon energy. Moreover, these economies have enacted measures to assist them in becoming green and encourage green initiatives, which function harmoniously with each other and have decreased carbon emissions, leading to the possible adaptation of green environmental investment sources. Hence, it is recommended that these economies boost their green financing activities, low‐carbon emissions, and economic development so that eco‐innovation and ecological investment can be made properly.
