Lower Dutch greenhouse gas emissions in 2014

The Dutch statistics bureau, CBS, released a press statement today containing new figures for Dutch greenhouse gas emissions in 2014 (not yet available in Dutch).
Dutch emissions were lower across the board, except for energy companies, which used more coal. Traffic related emissions have dropped 7% in accordance with IPCC methods. The CBS mentions two causes:
1. cars are more efficient and more often use alternative fuels such as electricity and CNG
2. more drivers refuel across the border after fuel taxes were increased.
When cars are filled up across the border the emissions count abroad. Electric driving reduces carbon emissions because the emissions for electricity production are counted towards energy companies and not to traffic.
