Environmental Policy vs. the Reality of Greenhouse Gas Emissions from Top Emitting Countries

The 21st century climate crisis has been compounded by the COVID-19 health crisis and the Russian war. What at first appeared to be an opportunity to move towards sustainable growth and development has turned into the opposite. In this context, it seems necessary to pause and analyze what countries are doing and where they are heading in order to ensure that their environmental efforts are not in vain. This article analyzes the environmental policies of the seven countries emitting the most GHGs from 1990 to the present day and compares them with the reality of their emissions. These behaviors are extrapolated into the future and, finally, conclusions are drawn as to which countries are not fully living up to their commitments, which have implemented the most effective measures, and where particular attention needs to be directed for maximum efficiency in decarbonizing the energy mix.
