ICT development and maritime transport CO2 emissions: evidence from cross-country panel data

Maritime transport’s critical role in global trade is increasingly challenged by its substantial CO2 emissions. Recent empirical analysis, utilizing cross-country panel data from 111 nations (2019-2023), reveals a significant inverse relationship between ICT development and maritime transport CO2 emissions. Notably, this reduction effect diminishes as maritime transport scale expands, demonstrating a threshold effect. Digital infrastructure development offers a valuable pathway to decarbonization, though its impact is contingent upon activity levels—a finding underscored by related coverage, such as IBIA’s response to maritime violence impacting seafarers.

Climate change is shifting malaria hot spots in Africa
