Regulation of Air Pollution: Switzerland

Air Pollution ControlGreenhouse Gas Emissions ReductionRenewable FuelsEven though the air quality in Switzerland has improved since the 1980s, pollution continues to be higher than the ambient limit values set out in the relevant legislation. Air pollution reduction measures are mainly codified in the Environmental Protection Act (EPA). The EPA contains general provisions that apply to all aspects of environmental protection and is supplemented by various detailed implementing ordinances. For the area of air pollution control and reduction these are in particular the Ordinance on Air Pollution Control (OAPC), the Chemical Risk Reduction Ordinance, the Ordinance on Incentive Taxation of Petrol and Diesel with a Sulfur Content of More Than 0.001% (PDSO), the Ordinance on the Incentive Tax on Extra-Light Heating Oil with a Sulfur Content of More Than 0.1% (ELHOO), and the Ordinance on the Incentive Tax on Volatile Organic Compounds (OVOC).The legislation is mainly focused on reducing air pollution from respirable particulate matter (PM10), nitrogen oxide...
