Hvad angår støttens proportionalitet, skal den pågældende medlemsstat vise, at hver enkelt modtager betaler en del af den nationale afgift, der stort set svarer til miljøresultaterne, at modtageren betaler mindst 20 % af den nationale afgift, medmindre en lavere sats kan begrundes, og at lempelser eller fritagelser er betinget af, at der indgås aftaler med henblik på at nå miljøbeskyttelsesmål [75].
With regard to proportionality, the Member State has to demonstrate that each individual beneficiary pays a proportion of the national tax level which is broadly equivalent to its environmental performance, or at least 20 % of the national tax, unless a lower rate can be justified, and that the reductions or exemptions are conditional on the conclusion of agreements aimed at achieving environmental objectives [75].
