While other three countries are increasing, United Kingdom only maintained 11 tonnes of carbon dioxide emissions for a year between 1967 and 1978. Then for nine years until 1987, Co2 emissions for both countries, Sweden and United Kingdom, have decreased dramatically. By contrast Co2 emissions for Italy and Portugal have increased sharply. And until 1997, Italy and Portugal shows the increasing rate while Sweden and United Kingdom decreasing rate. Moreover, two countries, Italy and Portugal, maintained and still increase, respectively until 2007. By contrast, United Kindom and Sweden still decrease. In conclusion, Co2 emissions for Sweden has the most fluctuated rate for 20 years between 1967 and 1987, comparing with the other three countries. |
