The graph below shows average carbon dioxide CO2 emissions per person in the United Kingdom Sweden Italy and Portugal between 1967 and 2007

The graph illustrates data on average carbon dioxide discharged by individuals in four countries like the UK, sweden, italy and portugal during the period 1967 and 2007.

Overall, it is clear that, the total amount of co2 emission decrease between these years. The decline of carbon dioxide from sweden was particularly significant.

portugal accounted at nearly 2 metric tonnes of co2 emission in 1967. There was then an increased to over 2 to approximately 4 tonnes in 1987. Similarly, In italy, each citizen released more co2 as time passes, it reached 2 metric tonnes to 8 metric tonnes with the given time period. Conversely, britain reduced its levels gradually from 12 to 10 in that same period. However, In 1967 sweden co2 emission figure was 8 metric tonnes then again increased it at 10 metric tonnes, later over the time period sweden figure fall down at reached at nearly 5 metric tonnes in 2007.

Even though co2 emission kept falling steadily britain still ranked the first with over 8 tonnes of emission. Both italy and portugal had a regular hold ranked second and third with nearly 8 tonnes and 6 tonnes. Meanwhile, sweden position at fourth with 5 tonnes, which is exactly the same as portugal.
