SO2 Kårstø. Environmental consequences from increased emissions. NILU OR
Norwegian Institute for Air Research (NILU) has performed dispersion calculations of emissions to air.
2011
The Air Quality in Oslo in 2025 will be worse than previously expected. If the present trend of a high percentage of sold diesel passenger cars will continue it will make the NO2 levels from light vehicles higher in 2025 compared with 2010.This is due to higher emissions of diesel cars in real driving cycles compared to the emissions standards. The calculation of NO2 concentrations in 2025 shows levels that will violate the directives¿ limit values in a large area of Oslo.
Calculations are done for 2010 and 2025 and results from totally 9 dispersion calculations are shown. Firstly 4 reference calculations are considered looking at the effect of the difference of real emissions factors taken from measurement under typically urban driving-cycle compared with the emission standards. There have also been done 3 mitigation calculations with incentives for lower diesel cars sales numbers and two short-time measures limiting the use of cars.
None of these measures are sufficient for keeping the limit values in Oslo and Bærum in 2025 and hence more measures are needed.

Environmental Management Report 2010. NILU OR
One of NILU's main goals is to study the impact of pollution. It is thus very important for the institute to have control of the impact the institute's own activities may have on the environment and to reduce the impact as far as possible.
NILU has for many years been working to reduce the impact. In order to take this one step further, it was decided that the institute should restructure the work according to a relevant environmental standard and to seek certification according to the same standard.
The chosen standard is ISO 14001:2004 (Environmental management systems - Requirements with guidance for use) and NILU achieved certification according to this standard in October 2010.

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.

EAD air quality monitoring network. Site survay for 10 new stations. NILU OR
Recommendations for additional monitoring stations in Abu Dhabi have been based on monitoring criteria and the objectives for measurements. It has been stressed that measurements have to be performed based on a number of permanent air quality stations. Also the meteorological measurements have to be co-ordinated with the permanent stations.
Based on the evaluations performed in Abu Dhabi, we have proposed three sites which should be developed and started immediately (1-3). Another three areas have been indicated for future and further evaluations. However, we believe that there will be a need in the near future also for measurements in these areas.
