With a 2019 total population of over 494 million people (USA 329 million, Mexico 128 million and Canada 37 million), North America comprises 6.4% of the global population. Relative to other countries, North American countries have low population densities per square kilometre (Mexico 64 people, USA 35 people and Canada 4 people) ( [[#United%20Nations--2019|United Nations, 2019]] ). Population projections indicate a steady growth in the three countries, which will exert pressure on consumption and increase risks under climate change ( [[#United%20Nations--2019|United Nations, 2019]] ). North America is also responsible for about a quarter of global greenhouse gas (GHG) emissions. Since 1990, North American GHG emissions have increased by almost 18% ( [[#Ritchie--2020|Ritchie and Roser, 2020]] ), and in 2019 the region was responsible for 5.9 MtCO 2 emissions worldwide ( [[#Friedlingstein--2020|Friedlingstein et al., 2020]] ). In terms of annual CO 2 emissions per capita, in 2019 Canada had 15 metric tons of CO 2 per person (tCO 2 per person), the USA had 16 tCO 2 per person and Mexico had 3.4 tCO 2 per person ( [[#Friedlingstein--2020|Friedlingstein et al., 2020]] ).
