I found the below chart in a test for university access in Sweden, with the following question:
How large was the total emission of nitrogen oxides caused by Swedish consumption under the period 2004-2008?
I have the correct solution, but it does not match my answer. I reasoned like this:
- Both 2004 and 2008 should be included, so we have 5 years.
- The emissions abroad are about 112 thousand tons on average, so 112*5 = 560
- The emissions in Sweden are about 225 thousand tons on average, so 225*5 = 1100.
- So the total should be about 160+1100 = 1660.
However, apparently the correct answer is 1100.
I am quite sure I am missing something obvious, but I cannot figure it out.
Translation of the most important terms:
Utsläpp i Sverige: emission in Sweden
Utsläpp utomlands: emission abroad (caused by imports).
The original question in Swedish:
Hur stort var det sammanlagda utsläppet av kväveoxider orsakat av svensk konsumtion under perioden 2004-2008?
