Based on the information provided:
- Denmark's emissions were approximately 8 in both 2009 and 2010.
- Finland's emissions increased from approximately 10 in 2009 to a little over 11 in 2010.
- Iceland's emissions decreased slightly from a little over 6 in 2009 to slightly less in 2010.
- Norway's emissions increased from almost 10 in 2009 to nearly 12 in 2010.
- Sweden's emissions increased from almost 5 in 2009 to over 5 in 2010.
Analyzing the statements:
-
Iceland produced more total carbon emissions than Denmark.
- This is false. Denmark had around 8 metric tons, while Iceland had a little over 6 metric tons in 2009, meaning Denmark had higher emissions.
-
Sweden reduced carbon emissions the most.
- This is false. Sweden's emissions increased from almost 5 in 2009 to over 5 in 2010, while Iceland saw a decrease in emissions.
-
Norway produced twice as much carbon emissions as Finland.
- This is false. Norway's emissions almost 10 in 2009 and nearly 12 in 2010 is not double that of Finland's emissions, which were approximately 10 in 2009 and a little over 11 in 2010.
-
All countries but Iceland had an increase in emissions.
- This is true. Denmark had stable emissions, while Finland, Norway, and Sweden all saw increases.
The correct response is: All countries but Iceland had an increase in emissions.
