The project - background and motivationp j g

• Growing LNG trade worldwide, European growth rate 21%

• LNG trade more liquid short vs long term more commercial• LNG trade more liquid, short vs long term, more commercial

• More focus on transparency and accuracy

• Innovations: off-shore LNG, small-scale LNG distribution

• Sound metrological framework not yet fully in place

• 1% uncertainty = 440 M€ per year in 2010

• 1% uncertainty = 900 M€ per year in 2015
