CO2 emissions in the region vary considerably. The highest emissions come from South America, while the lowest and relatively more stable emissions come from the Caribbean. Between 1990 and 2000, CO2 emissions from South America increased by more than 40%, mainly because of increased emissions from transportation, industry and electricity and heat production. Although the Caribbean is one of the areas in the world that is most vulnerable to climate change, it contributes the least to the problem.
