Since most developing countries located across Latin America and the Caribbean have bountiful deposits of mineral resources and are also large-scale mineral exporters, this study appraises the validity of the hypothesis regarding the carbon curse of mineral resources using a sample of 13 developing nations from this region. Besides, the potency of technological innovation finance in containing carbon emissions, exerted from utilization of mineral resources, is also explored. In this regard, considering the period from 1998 to 2021 and employing advanced panel data estimators, the results verify the hypothesis regarding the carbon curse of mineral resources by linking more mineral resource utilization with higher carbon discharges. Besides, providing more technological innovation finance is observed to reduce carbon emissions in the long run. More importantly, the results affirm that scaling such financial provisions offsets the carbon discharges associated with mineral resource utilization, especially by acting as a moderator between mineral resource use and carbon emissions. Hence, these findings certify that technological innovation financing is highly effective in helping the concerned nations avoid the carbon curse of mineral resources. Furthermore, results show that implementing trade liberalization policies reduces carbon emissions while the pollution haven hypothesis is also verified based on the finding of the positive nexus between foreign direct investment receipts and carbon emissions. Hence, considering these analytical outcomes, several environmentally sustainable mineral resource-based policies are suggested for the concerned Latin American and Caribbean countries.
