In the view of limiting the global temperature increasing, the green house emissions respectively, Romania has to act immediately, especially in the energetic efficiency field and of energetic renewable sources. The actions regarding the energetic efficiency and the energetic renewable sources will contribute both at diminishing the negative pollutions impact on the environment and at limiting of Romania dependency for the energy import. The reinforcement of developing conditions for the biofuel sector in Europe has been materialized by drawing up the Directive 2003/30/CE, having as target the promoting of biofuels usage in transport. That directive provides the introduction on the market by each EU member state of a minimum production of biofuels and other renewable fuels, calculated on the base of the energy contained of all types of petrol and diesel used in transport. This directive has been transposed in Romanian legislation by the Governmental Decision no. 1844/2005, concerning the promoting of biofuels and other renewable fuels usage in transport, completed and rectified by the Governmental Decision no. 456/2007 which stipulates a phasing for introduction on the Romanian market of the blended biofuels and conventional fuels.
