The line illustrates average CO2 emissions per person in four different nations – Ireland, Sweden, France and Spain – from 1970 to 2010.
Overall, it is clear that Sweden saw the biggest change, with a general downard trend.France also recorded a decline, though it was less pronounced;while emissions in Ireland and Spain increased throughout the period.
Looking first at the CO2 emissions in Sweden, this country recorded the most substantial change.This country started the period as the leading emissions among the four countries at 14 metric tonnes per person, experienced a fall to just below 10 metric tones in the next 2-years, and continued to decrease steadily over the following two decades, reaching approximately 8 metric tonnes per capita by 2010.Focusing on Spain, with an initial standing of 4 metric tonnes per capita.The figures had skyrocketed to just below 8 metric tonnes by individual and concluded the span.
Turning to remaining countries, France and Ireland, the changes were not as dramatic. The former recorded emissions worth about 9 metric tonnes per person, maintaining this level for a decade, after which this figure went down to approximately 6 metric tonnes per person over the following 30 years. It, however, continued to decline gradually, reaching around 8 metric tonnes per person in 1990, 7 in 2000, and finally dropped significantly to hit another low of approximately 6 metric tonnes by 2010. As for the latter, this country jumped from just above 8 in 1970 to roughly 6 metric tonnes per individual, after a decade. From that year on, this figure reach a peak at approximately 11 million tonnes by individual in the following decade and then dropped significantly to 8 metric tonnes per person.
