A recent evaluation by the European Commission has shed light on the effectiveness and relevance of Directive 1999/94/EC, which mandates the provision of information on fuel consumption and CO2 emissions for new passenger cars sold or leased in the EU. This directive, known as the “car labelling Directive,” aims to empower consumers to make informed decisions when purchasing or leasing vehicles, potentially steering demand towards more fuel-efficient and lower CO2-emitting cars.
