Nuclear energy, renewable energy, and alternative energy sources are all crucial for sustainable
green energy. However, the existing literature often needs to pay more attention to the role
of nuclear energy in achieving sustainable development goals. This study analyzes the impact of
green technological innovation, nuclear energy consumption, and trade openness on environmental
quality in the US. The authors used the ARDL bounds to identify cointegration relationships, which
is appropriate for this study’s dataset as it works well with smaller samples. They also used the
Toda–Yamamoto causality test to examine causal links. The ARDL cointegration results indicate a
significant long-term relationship between CO2 emissions, green technological innovation, nuclear
energy consumption, and trade openness. Green technological innovation has a negative impact
on CO2 emissions. Higher nuclear energy consumption is associated with lower CO2 emissions,
while greater trade openness is associated with higher CO2 emissions, although these effects are less
certain. The results suggest promoting green technological innovation and nuclear energy can be
effective strategies for reducing CO2 emissions, while the impact of trade openness requires careful
consideration due to its potential to increase emissions.
