# Commission Decision of 30 June 2009 establishing a template for National Renewable Energy Action Plans under Directive 2009/28/EC of the European Parliament and of the Council (notified under document number C(2009) 5174) (Text with EEA relevance) (2009/548/EC), Division: BOX — How to calculate the ‘aviation capping mechanism’ in the Renewable Energy Directive

Extent: E+W+S+N.I.

Assume Country A has a share of aviation energy consumption (AEC) of its total gross final energy consumption (GFEC) of X:
X = AEC/GFEC
Assume X > 6,18 %
In this case the cap implies that for the purpose of assessing compliance,
GFECadjusted = GFEC – AEC + AECadjusted
where AECadjusted = 0,0618 * GFEC
In other terms
GFECadjusted = GFEC – AEC + 0,0618 * GFEC =
= GFEC – X * GFEC + 0,0618 * GFEC =
= GFEC * (1,0618 – X)
The ‘adjustment’ as a % of the real GFEC and as a function of X is therefore
Adjustment = (GFEC – GFECadjusted)/GFEC =
= X – 0,0618
