Technological progress in the automobile industry will be of major importance in bringing to market more efficient technologies in terms of fuel consumption as well as technologies based on alternative fuels such as LPG, liquefied gas, biogas, hydrogen, electricity and others. In order to ensure road traffic with the previously mentioned means, the adequate development of the road infrastructure is necessary. the aforementioned means, the adequate development of the road infrastructure is necessary. A very important role in the reduction of GHG emissions from road transport is played by the application of the provisions of Directive 2009/33/EC of the European Parliament and of the Council of April 23, 2009 regarding the promotion of non-polluting and energy-efficient road transport vehicles, Regulation (EC) 443/2009 of the European Parliament and of the Council of 23 April 2009 establishing emission performance standards for new passenger cars, as part of the Community&#39;s integrated approach to reduce CO emissions from light-duty vehicles, targeting CO from new cars, which provides for an objective of reaching an average emission level in 2020 of 95 g CO/km and Regulation (EU) 510/2011 of the European Parliament and of the Council of 11 May 2011 establishing performance standards for new light commercial vehicles as part of the Union&#39;s integrated approach to reducing emissions CO generated by light-duty vehicles, targeting CO emissions from new light-duty vehicles, which sets a target of achieving an average emissions in 2020 of 147 g CO/km.
