The law amends a number of articles of the law of August 1st, 2007, on the natural gas market. The law seeks to improve the environmental footprint of the natural gas market as well as energy efficiency on the supply and distribution side.
 
 The law obliges natural gas suppliers to purchase the production of biogas, gas produced by biomass or other types of gas based on renewable resources, to inject it in their networks. The law also sets targets of energy savings for suppliers.
