In 2008, the European Union launched the &#39;Climate-Energy Package&#39; (so-called &#39;20-20-20 Package&#39;), with the following energy and climate targets for 2020: O A unilateral EU commitment to reduce by at least the 20% greenhouse gas emissions by 2020 compared to 1990 levels. The interventions needed to reach the 2020 targets will continue to yield results beyond this date, helping to reduce emissions by around 40% by 2050. A binding target for the EU to contribute 20% of energy from renewable sources to gross final consumption by 2020, including a 10% target for biofuels. o A 20% reduction in primary energy consumption compared to levels forecast in 2020, to be obtain through energy efficiency measures. This objective, only stated in the package, was subsequently declined, albeit in a non-binding manner, in the energy efficiency directive definitively approved in October 2012. O L&#39;Ita lia fully adhered to the spirit of the Climate-Energy Package and implemented the European regulatory framework, with a declination of the objectives that it provides for 2020: A binding commitment to reduce emissions equal to 18% overall, divided as follows: 21% for ETS (Emission Trading System, in particular electricity generation) sectors and 13% compared to 2005 in sectors not covered by the ETS system. A binding commitment of 17% of energy from renewable sources, including a 10% target for biofuels. A commitment to reduce primary energy consumption by 20% by 2020 compared to expected levels. In the new Energy Efficiency Directive approved in June 2012, various measures have been identified that are available to Member States to achieve this goal.
