Air pollution - Outlook 2020 (Switzerland)
- Air pollution
Emissions are projected to decrease to 2020
Under current policies, emissions of air pollutants will further decline towards 2010. After 2010, with continuation of current policies and additional measures, emissions of NOx, SO2, NMVOC and ammonia are expected to continue to decline.
Number of exceedances will strongly decline
With current and proposed national and international legislation and the expected effect on emissions, the number of exceedances will strongly decline by the year 2020.
Premature mortality from particulate matter is projected to decline further
If proposed national and international policies are put in place, the number of life-years lost will continue to decline to 2020. Where health effects are caused mainly by primary emitted combustion-related aerosols such as soot, health improvements may even be greater.
Critical loads may continue to be exceeded to 2020
While emissions of acidifying and eutrophying substances are expected to decrease, critical loads, particularly those for eutrophication, may still be exceeded in 2020.
