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

The line graph presents the average emissions of carbon dioxide in metric

tonnes

scale per person in four European countries in the period from 1967 to 2007. In general, the scale of emissions of CO2 in Italy and Portugal increased significantly,

while

in Sweden and the UK, its discharge level declined during 40 years of research from 1967 to 2007. During the first 10 years, Sweden’s CO2 emission by person grew rapidly from almost 8.8 metric

tonnes

in 1967 to nearly 10.3 metric

tonnes

in 1977.

Furthermore

, both the UK’s and Sweden’s rates plunged from less than 11 metric

tonnes

and 10.3 metric

tonnes

to approximately 8.8 metric

tonnes

and 5 metric

tonnes

, respectively.

By contrast

, Italy’s and Portugal’s citizens’ carbon dioxide discharge rose gradually from the very beginning, starting from just over 4.2 metric

tonnes

and 1.2 metric

tonnes

in 1967 and ending up at 7.8 metric

tonnes

and 5 metric

tonnes

in 2007, respectively.
