Actually, EU and their countries have been developed a set of laws and policies with the goal to reduce air pollution. The changes in our energy model, reducing the use of solids fuels like wood and coal, and promoting the use off renewable energies. Its can be the first stage in the changing of the model, however, are not sufficient to safeguard human health and the environment. We have to take further action.

The total cost to implement the Clean Air Policy package in the EU is estimated at about Є2.2 billion a year by the time we reach 2030. However, about Є3.3 billion a year could be saved in direct costs otherwise caused by air pollution, plus are further Є40 to Є140 billion in indirect costs ( for example, related to improvements in people's health). This means that expected benefits to society are more than 20 times the cost of implementing the legislation.

In the city where I live actually, we don't have a lot of problems with the air pollution because we don't have a high level of industrial production and the traffic's pollution isn't a problem without solution, by the moment. However, since years, all the summers we are started to have other problems derived to the ground level ozone. As we know the ground level ozone is produced by chemical reaction of NOx, and VOCs in the presence of sunlight. It is seen as “summer smog”. CH4 has a long lifetime in the atmosphere and therefore plays a significant role in the generation of O3 (CH4 reacts with carbon monoxide to produce O3 ). The ozone is a greenhouse contributing to warming of the atmosphere. High levels can cause breathing problems, reducing lung function an trigger asthma. Reduce growth rates by reducing carbon dioxide uptake by vegetation. Impairs plant reproduction.

The ground level ozono, reduces the growth rate of crops including wheat, soybeans and rice. In 2011 about 18% of agricultural area in Europe was exposed to O3 levels above target values for protecting crops.

The development and implementation of the clean air policy package in the EU, can avoid 224.000 of premature deaths. The application of additional measures to control air pollution can suppose the emissions reduction of 25% PM, 7% SO2 , 3% NOx , 17% NH3 , 6% VOC.
