Prediction of surface temperature and CO emission of leading emitters using grey model EGM (1,1, α, θ).

The current study projects the increase in surface temperature and CO emissions using the EGM (1,1, α, θ) grey model for the six most significant CO contributing countries, namely China, the USA, India, Russia, Japan, and Germany. The study uses time series data for surface temperature (in degree celsius) from 2010 to 2020, and CO emission (metric tons per capita) data from 2009 to 2019. The empirical results show a downward trend in CO emissions from Japan, Germany, the USA, and Russia by 2028.
