Regional contributions to global human-caused GHG emissions 
continue to differ widely. Historical contributions of CO2 emissions 
vary substantially across regions in terms of total magnitude, but also 
in terms of contributions to CO2-FFI (1650 ± 73 GtCO2-eq) and net 
CO2-LULUCF (760 ± 220 GtCO2-eq) emissions (Figure 2.2). Variations 
in regional and national per capita emissions partly reﬂect different 
development stages, but they also vary widely at similar income 
levels. Average per capita net anthropogenic GHG emissions in 2019 
ranged from 2.6 tCO2-eq to 19 tCO2-eq across regions (Figure 2.2). 
Least Developed Countries (LDCs) and Small Island Developing States (SIDS) 
have much lower per capita emissions (1.7 tCO2-eq and 4.6 tCO2-eq, 
respectively) than the global average (6.9 tCO2-eq), excluding 
CO2-LULUCF. Around 48% of the global population in 2019 lives in countries 
emitting on average more than 6 tCO2-eq per capita, 35% of the global 
population live in countries emitting more than 9 tCO2-eq per capita70 
(excluding CO2-LULUCF) while another 41% live in countries emitting less 
than 3 tCO2-eq per capita. A substantial share of the population in these 
low-emitting countries lack access to modern energy services. (high conﬁdence)

Net GHG emissions have increased since 2010 across all major 
sectors (high conﬁdence).
