The systematic advancement of land urbanization coupled with the pursuit of a low-carbon economy constitutes a critical challenge faced by numerous nations across the globe. Utilizing panel data spanning 195 countries from 1990 to 2020, this study employed a panel regression model to scrutinize the impact mechanisms of land urbanization on CO[sub.2] emissions across income groups. The findings revealed a consistent overall increase in both land urbanization and per capita CO[sub.2] emissions during the period examined, with marked disparities evident among countries of varying income levels. The regression analysis further identified an “inverted U-shaped” curve relationship between land urbanization and per capita CO[sub.2] emissions in the global context and within high-income panels. Conversely, a “U-shaped” curve relationship was discerned in lower-middle-income nations, whereas a linear relationship was observed in upper-middle-income and low-income countries. These insights serve to deepen the understanding of the CO[sub.2] emission implications of land urbanization across countries at different development stages. This study underscores the necessity for countries to attentively consider their unique stage of development when devising CO[sub.2] reduction policies, reinforcing the complex interplay between urbanization, economic categorization, and environmental stewardship.
