| Abstract | Algeria adopted an ambitious program of sustainable development and renewable energy to expand the use of renewable energies and to save fossil energy reserves. The energy efficiency program (EEP), which is focused on three main sectors-transport, residential, and industry-is aimed at diversifying the energy sources and at reducing between 7 and 22% pollutant emissions by 2030. The present study is a first attempt to evaluate the impact of the EEP policies on air quality and human health by 2030, in an urban area (the capital Algiers), using a numerical modeling approach. Three emission scenarios were developed for 2030: (i) business as usual (BaU), (ii) governmental energy policies, and (iii) additional measures. The air pollutants nitrogen dioxide (NO2) and particulate matter (PM10) were considered. Results suggest that the maximum annual concentration levels for PM10 and NO2 will increase from 122 to 129 mu g/m(3) and from 91 to 124 mu g/m(3), respectively, between 2012 and 2030 (BaU scenario). These values are much higher than those set by national and international guidelines. The planned governmental energy policies could reduce approximately 20 mu g/m(3) of PM10 and 15 mu g/m(3) of NO2 by 2030, representing a reduction up to 15% for both pollutants compared to the BaU scenario. Considering governmental and additional measures, a reduction of around 35 and 30 mu g/m(3) for PM10 and NO2, respectively, is estimated, which corresponds to reductions up to 24% for both pollutants. Based on the obtained results, the implementation of additional air quality planning strategies is strongly recommended to promote the citizens' health. |
