Not a definitive source but it does seem that 520d fuel economy on average is getting worse over time.
There are at least two aspects to take into account before reaching a conclusion regarding the yearly list you pointed at.
Firstly, that the number of car is very small and therefore the average quoted is not very reliable.
Secondly, new cars tend to consume more. It takes at leasts 10,000 miles to reach the optimum consumption. So, it is not surprising to find that the 2014 cars seem to consume more.
