The EU has introduced new air pollutant emission targets. Compliance to meet these targets requires models that combine data about climate change and air quality.
The latest review of the EU Air Policy aims to develop better and practical information by integrating climate change and air quality data. The developments made in the measurement and estimation of emissions from various sources has increased the possibility of meeting the new air pollutant emission targets.
Quality of air gets affected by man-made as well as natural emissions. Separation of background emissions from other biological and natural sources has not been possible. Professor at the Institute for Energy Economics and the Rational Use of Energy at Stuttgart University, Rainer Friedrich, commented that the NatAir project helped improve the emissions estimates in many areas. The results were used for the CHIMERE chemistry-transport model, which provides forecasts of aerosols and ozone, and long-term simulations.
A Senior Scientist at the Centre for Ecology and Hydrology in Edinburgh, Stefan Reis, states that as anthropogenic emissions are being reduced due to more stringent controls, the quantification of biogenic and natural emissions has gained more relevance. They may be the major contributors of air pollution.
A Professor of Atmospheric Chemistry in the Department of Chemistry at York University, Alistair Lewis, states that data of air quality alone is not sufficient for prediction of climate change. Atmospheric models coupled with biogenic emission models may influence each other and these may help derive accurate data. A new reduction target has also been set by the EU for particulate matter emissions, which are lower than previous levels.
