(28) This Directive should not prevent contracting authorities and contracting entities from giving preference to the latest Euro Norms in the purchase of vehicles for public transport services before those standards become obligatory. It should also not prevent contracting authorities and contracting entities from giving preference to alternative fuels, for example hydrogen, Liquefied Petroleum Gas (LPG), Compressed Natural Gas (CNG) and biofuels, provided the lifetime energy and environmental impacts are taken into account.
