The graph shows the changing levels of CO2 produced by 4 European countries over a 40-year period.
Generally speaking, levels of emissions improved through a decrease in the levels of CO2 of the highest polluters over the period, and a more recent levelling off from countries whose levels were increasing prior to this.
Looking first at the declining levels produced by the UK and Sweden, it can be seen that, despite a dramatic fluctuation in levels produced by Italy during the first 20 years, levels emitted by both countries declined relatively sharply. To be more exact, UK levels fell about a quarter, from approximately 12 to 9 metric tonnes, and those in Italy almost halved from roughly 9 to about 5. 5 metric tonnes.
Combined with these falling rates, the volume of CO2 emitted by Italy and Portugal, while rising throughout the first three-quarters of the period, levelled off in the final 10 years. More precisely, in the last decade, these levels were around 9 and 5. 5 metric tonnes, respectively
