Dubai has undergone a remarkable transformation in the last two decades. It has managed to diversify its economy from fishing, pearl diving, and gold trading into one of the world’s leading cities for tourism, shipping, and finance. In recent years, the city has developed into a busy port and became a center for trade and commerce in the region. The rapid progress and urbanization occurring at an unprecedented scale resulted in various environmental challenges - one of which is the quality of air.

Dubai Municipality has been developing a range of strategies, policies and studies to address the air quality challenges of the growing city. One of the most important strategies is the Air Quality Strategy which aims to implement a smart, innovative and sustainable approach in achieving the 90% target of clean air days set by the National Agenda UAE Vision 2021

Supporting the effective air quality management and achieving the targets of the Strategy, Dubai Municipality operates an air quality monitoring network which provides a real-time air quality information on criteria pollutants issued under Federal Law No. (24) of 1999 for the Protection and Development of the Environment and implemented by the Cabinet Decree No. (12) of 2006 for the Regulation Concerning Protection of Air from Pollution. Monitoring provides statistics on the chemical composition and allows an assessment of the environmental policies and the outcomes of protective and mitigation actions.

Monitoring Stations

Dubai Municipality operates the Air Quality Monitoring Network (AQMN) comprised of thirteen (13) fixed stations to provide continuous and real-time air quality monitoring, and to track the criteria air pollutants: carbon monoxide, nitrogen dioxide, sulfur dioxide, ozone and particulate matter. Data is transmitted to a central database to determine the daily trend and compliance with the federal and local air quality standards.

The stations are strategically located, based on comprehensive and sophisticated modelling studies, to monitor pollutants within areas of high traffic, industrial and commercial activities and densely populated areas. Based on the location, the stations are categorized as urban, near-city, industrial and traffic. The AQMN also measures the meteorological parameters such as wind speed and direction, temperature, humidity, and total solar radiation, which influence the characteristics and origin of the air pollutants.

Quality Assurance

The quality assurance procedure for the monitoring stations is in accordance with the USEPA Quality Assurance Handbook for Air Pollution Measurement Systems. The monitoring stations are, additionally, certified to comply with the latest European Standards. A high-quality policy is adopted to ensure that ambient air quality monitoring results attain high degree of accuracy and precision. The stations are supported with the most advanced software and telemetry technology in order to ensure the high quality of captured data and seamless data transfer to the database. Timely inspections, calibrations and maintenance of the equipment are undertaken to ensure high quality level of captured data.

Network Expansion

Dubai is a dynamic city embracing a rapid growth in developments which are expected to continue in the coming years. As a result, an expansion plan for the air quality monitoring network is in progress with the aim to cover the new built areas in the Emirate and areas requiring continuous air quality monitoring. It is also planned to continuously upgrade the technology of the existing stations to ensure accuracy of the captured data and calculated AQI which are used as UAE’s National Agenda Air Quality Key Performance Indicators aimed at achieving 90% target of clean air days by 2021.

Federal Law No. (24) of 1999 for the Protection and Development of the Environment implemented through Cabinet Decree No. (12) of 2006 regarding the Regulation Concerning Protection of Air from Pollution has established national ambient air quality limits for the most common air pollutants; carbon monoxide, nitrogen dioxide, sulfur dioxide, ground-level ozone and particulate matter. These are called the criteria pollutants, as high concentration levels significantly affect the human health and the environment. The criteria pollutants are shown on the right.

The Air Quality Index (AQI) is a key international tool for reporting daily air quality. It provides valuable information about the local air quality and the related health effects. Determination of the AQI considers a concentration of all criteria pollutants and relates them to a single scale value. The AQI is calculated according to the US EPA AQI formula and classifications. AQI values are used in establishing UAE’s National Agenda Air Quality Key Performance Indicators aimed at achieving 90% target of clean air days by 2021.  As the AQI increases in value, the level of air pollution and the potential health impacts also increase.

The AQI result is divided into six categories of health concern, with each assigned a specific colour band for easier understanding of air pollution levels:

Dubai Municipality is currently establishing an online emission inventory platform. The Emission Inventory for Emirate of Dubai is a comprehensive and detailed estimate of air emissions of criteria pollutants, criteria precursors, and hazardous air pollutants from specific air emissions sources. The emission facilities are required to submit the source description, activity data and pollutant concentrations via an interactive online platform. A regularly updated emission inventory improves understanding of the relative contribution of each pollution source.

The emission inventory covers the following sources:

  • Main stationary sources of emitted pollutants, mainly power plants and industrial facilities; and
  • Mobile sources related to the road transport, aviation and maritime sectors.
Emission Inventory

Emission Inventory Objectives

The objectives of the online emission inventory for the Emirate of Dubai are:

  • Document the emission of pollutants into the air from mobile, stationary and area sources across the different economic sectors and activities, such as manufacturing and industrial facilities, power generation, on-road and non-road transportation;
  • Assess sectoral contribution to air quality;
  • Compile a database of air pollutants concentrations and emission sources in Dubai; and
  • Provide basis for the preparation of policies that influence air quality and its management.

Quality Assurance

The emissions data for stationary and non-stationary sources are evaluated based on the international guidelines – EMEP/EEA Air Pollutant Emission Inventory Guidebook 2016. The most common approach is to include the activity data information and coefficients that quantify the emissions per unit activity, called emission factors. The emission factors differ depending on the pollutant, sector and technology used. The basic equation is: Emissions = Activity Data x Emission Factor.
