Air quality in Europe - 2020 report
The Air quality in Europe report provides an annual assessment of the status and impacts of air quality and recent air quality trends. The report supports policy development and implementation in the field of air quality at both European and national levels.

Air quality in Europe - 2018 report
The current report presents an updated overview and analysis of air quality in Europe from 2000 to 2016. It reviews the progress made towards meeting the air quality standards established in the two EU Ambient Air Quality Directives and towards the World Health Organization (WHO) air quality guidelines (AQGs). It also presents the latest findings and estimates on population and ecosystem exposure to the air pollutants with the greatest impacts and effects. The evaluation of the status of air quality is based mainly on reported ambient air measurements, in conjunction with modelling data and data on anthropogenic emissions and their evolution over time.

Air quality in 7 Norwegian municipalities in 2015. Summary report for NBV results.
This report documents the methodology used to compile air quality information for the year 2015 in seven Norwegian municipality areas under the first phase of development of the Norwegian Air Quality Planning Tool, also called “Nasjonalt Beregningsverktøy” or NBV. It follows a similar structure to and complements the final report entitled “Air quality in 7 Norwegian municipalities in 2015 – Summary report for NBV results” (NILU rapport 21/2017) where information on air quality in the seven main city areas in Norway was presented.
This report constitutes a user guide for the NBV-services, available at http://www.luftkalitet-nbv.no, in municipal areas. It provides recommendations on how to best use each product for air quality planning purposes and explains the main strengths and limitations of the results. The NBV air quality data for municipalities is subject to larger uncertainties than the data available for the main Norwegian city areas and this has to be taken into consideration when analyzing the results.

Air quality impact assessment, Maria Gleta Power Plant, Benin. NILU OR
Concentrations of air pollutants from the 50MW Jacobsen Electro power plant in Benin has been estimated using two different dispersion models. SO2 emissions from the power plant operated with heavy fuel oil has proven to be the most critical option compared to national and international limit values. The SO2 concentrations will never exceed more than 37% of the national air quality limit values. For all other options, such as light fuel oil and gas, the concentrations will be less. Also the impact of NOx and PM10 will be relative to the limit values be less than for SO2. The CO2 emissions will represent less than 10 % of the national greenhouse gas emissions in Benin.

Air quality impact assessment, Kinyerezi, Dar Es Salaam, Tanzania. NILU OR
Concentrations of air pollutants from the 150MW Jacobsen Electro power plant planned for the Kinyerezi area near Dar Es Salaam, Tanzania has been estimated using two different dispersion models. The estimated annual average contribution to the ground level concentrations of NO2, SO2 , PM and CO is negligible compared to international and national standards. Only the highest one hour average concentrations may be of some concern.
The estimated absolute maximum hourly ground level concentrations of NO2 from the 150 MW gas fired power plant was found within about 2 to 3 km from the power plant. The maximum ground level concentration might reach 11 µg/m3 during very special meteorological conditions and wind from west.
Contributions to the ground level NO2 concentrations from the 150 MW power plant operated with Jet A1 liquid fuel is somewhat higher. It, however, never seems to exceed 32 µg/m3 (NOx as NO2) as a one hour average maximum concentration.
Over the city of Dar Es Salaam, about 15 km east of the plant site, the two plants will contribute during maximum conditions to about 12 to 20 µg/m3 NO2 .
The green house gas (GHG as CO2 equivalents) emissions will be less than 1 % of the present national emissions of GHG in Tanzania.

Air Quality Impact Assessment, Kinyerezi, Dar Es Salaam, Tanzania. Phase II process update. NILU OR
This assessment of emissions from a planned power plant improvement project in Kinyerezi (Tanzania) is a follow-up to the Phase I assessment conducted by NILU in 2012 of the 150 MW dual-fuel plant. This Phase II assessment focuses solely on natural gas driven power plant with a total of 8 generators for a total of 345 MW. Concentration distributions from the planned power plant were generated using TAPM (The Air Pollution Model), using 2009 as the study period to remain consistent with the Phase I assessment. Annual CO2 emissions are estimated at 1.5 million tonnes/year, this is .2% of the total emissions for the entire country of Tanzania. NOx is the pollutant being emitted from the plant with the greatest impact at the local level, with maximum (1-hour) concentrations found in surrounding communities ranging from 10.7 - 33.2 µg/m3. The average annual concentration in these communities, and across the grid is low (highest being 1.4 µg/m3). The planned power plant at Kinyerezi does not alone exceed any local ambient air quality limit values or WHO guidelines.
