The SO2 in the air in France amounted to 446 000 tonnes in 2007 against 1.33 million tonnes in 1990 and 3.2 million tonnes in 1980. In 2007, the major emitters of sulfur dioxide are energy conversion (49%) and manufacturing (33%). The sharp decline since 1980 (-86%) due to lower consumption of 'fossil fuels following the implementation of the power program, for actions to conserve energy and use less fuel sulfur. The latest advances (-67% between 1990 and 2007) result of the actions by manufacturers to promote the use of lower sulfur fuels and energy efficiency of plants and the industrialization of the French economy. Transport (-97%) and manufacturing (-66%) are the sectors most affected by this decline.
The international commitments of France imposes a further reduction in SO2 emissions. The Gothenburg Protocol of 1 December 1999 sets a maximum level of emissions for France 400 000 tonnes in 2010. The European directive of October 23, 2001 provides for an emissions cap of 375 000 tonnes in 2010. To meet these commitments, France leverages technology to limit sulfur content of liquid fuels and lower emission limits for combustion plants.
