Our World in Data: CO₂ and other Greenhouse Gas Emissions
Data sets and graphs of Our World in Data provides a historical to present day perspective of how CO2 emissions have evolved, how emissions are distributed, and the key factors that both drive these trends and hold the key to mitigating climate change. CO2 emissions are most typically measured and reported in terms of CO2 “production”. This accounting method is also sometimes referred to as “territorial-based” emissions because it reports emissions as those emitted within a country’s given geographical boundaries. As a result, this method takes no account of emissions which may be imported or exported in the form of traded goods. “Consumption-based” accounting adjusts CO2 emissions for this trade of emissions and more accurately reflects the emissions necessary to support a given country’s way of living. Based on the updated data gathered by Peters et al. (2012) and the Global Carbon Project, if we switched to a consumption-based reporting system (which corrects for this trade), in 2014 the annual CO2 emissions of many European economies would increase by more than 30% (the UK by 38%; Sweden by 66%; and Belgium’s emissions would nearly double); and the USA’s emissions would increase by 7%. On the other hand, China’s emissions would decrease by 13%; India’s by 9%; Russia’s by 14% and South Africa by 29%.
