Does patents on environmental technologies matter for the ecological footprint in the USA? Evidence from the novel Fourier ARDL approach

The outcome of patents on environmental (POET) technologies on the EF in the USA has not been comprehensively explored. Therefore, to close this breach in the literature, the present study discovers how patents on ecological technologies affect ecological footprint (EF) in the USA while regulatory for GDP and EC using the Fourier-based approaches. The conclusions of the present study reveal that POET are an important predictor of EF in the USA and cause a reduction in ecological deprivation in the long run; as expected, economic growth negatively affects environmental sustainability. The outcomes suggest that it is possible to resolve conflicts between the economy and the environment by using technological innovation. The USA government must reconsider its policy focus, particularly on coal energy sourcing and industrial energy, while continuing with heavy investments in its ambitious renewable energy technology development plan. Moreover, the government should continue to promote investments in environmental technologies.
