Which test to use?? Assessing changes over years

Hi, I have a set of data of carbon levels for 4 different sectors from 2005-2017 with one overall total measurement for each year for each sector (e.g agriculture - 2005 - 34.1;transport-2005-1069.2; Domestic - 2014 - 2074.2). I'm wanting to compare each sector to see which was more successful and if there's any correlations between the changes over the years between the sectors.

Is this possible? What would my data classify as? Which tests should I use?
