The graph below shows average carbon dioxide (CO2) emissions per person in the United Kingdom, Sweden, Italy, and Portugal berween 1967 and 2007. Summarise the information by selecting and reporting the main features, and make comparisons where relevant.

The line chart illustrates the average carbon dioxide (CO2) release per capita in four European countries over a period of four decades (1967–2007).

Overall

, it is clearly observable that UK residents produced the largest amount of CO2 over the entire period,

whereas

people who were living in Portugal produced the least amount of

this

gas. In 1967, the figure for CO2 emissions by UK residents was nearly 11 metric

tonnes

,

while

these figures for Portuguese and Italian were lower at approximately 1.5 metric

tonnes

and just over 4 metric

tonnes

, respectively. From

saw a moderate decrease of 2 metric

tonnes

.

By contrast

, the amount of CO2 that was generated by Italian and Portuguese people grew to well under 8 and 6 metric

tonnes

, respectively.

On the other hand

, the average emissions by individuals who had been living in Sweden experienced a pivotal point, transitioning from an uptrend to a downtrend in 1977. From 1967 to 1977,

this

figure rose from nearly 9 to just over 10 metric

tonnes

, after which, until 2007, it fell markedly by around 4.5 metric

tonnes
