Green Riyadh Project

Green Riyadh is one of Riyadh’s Four Megaprojects launched by the Custodian of the Two Holy Mosques, King Salman Bin Abdulaziz, on 19 March 2019. The project will be a milestone that contributes to fulfilling a key goal of the Saudi Vision 2030 to promote Riyadh’s position among the world’s top 100 most livable cities.

The Green Riyadh Project includes planting 7.5 million trees across the capital in gardens, parks, mosques, schools, healthcare facilities, King Khaled International Airport and most of the city’s roads, streets, car parking spaces, and valleys

To secure the required irrigation water for this project, new irrigation networks will be established to use recycled water which is usually being dumped in the valleys. This will raise the quantity of the recycled water utilized across the city from 90,000 m3 to over 1 million m3. Only native shade plant species compatible with Riyadh’s environment are used for the project.

Additionally, this project will have supportive elements and activities including a network of nurseries to provide the project with seedlings, regulations to ensure afforestation within the public/private projects, and awareness campaigns to encourage voluntarily engagement.

Green Riyadh will help improve air quality and reduce average ambient temperature, in addition to increasing the city’s per capita green space from 1.7 to 28 square meters and the total green space in the city to 9% or 541 square kilometers. Also, it will promote and preserve the natural areas and biodiversity in the city of Riyadh and its surroundings.

Project Elements


  • Planting 7.5 million trees across the capital as follows:
    • 5,939 schools
    • 2000 car parking sites
    • 1,665 public facilities
    • 387 healthcare facilities
    • 64 universities
    • 16,400 kms of streets and roads
    • 1,100 kms green belts along utilities lines (power stations oil pipelines, etc.)
    • 272 kms valleys
    • 175,000 square kms of empty land
    • 3,331 neighborhood gardens
    • 43 parks
    • 8,800 mosques

Tree species

About 72 native shade plant species compatible with Riyadh’s environment will be used for the project.

Key enablers

  • A new water treatment network for irrigation with a daily capacity of 1,000,000 m3.
  • A network of plant nurseries to provide the required seedlings and trees.
  • Improved urban regulations to enhance afforestation in both public and private projects.
  • Awareness initiatives to encourage voluntarily engagement.

Project Benefits

  • Reduce ambient temperature by 2 Celsius degrees during summer season
  • Reduce temperatures by 8-15 Celsius degrees in selected intensively afforested locations across the city
  • Improve the air quality by reducing CO2 concentration by 3-6%
  • Reduce dust concentration in the air
  • Reduce annual power consumption by 650 gigawatt/hour, through encouraging the principles of Green Building techniques that use green ceilings and walls
  • Improve readiness for handling rainwater and minimize the flood hazards
  • Improve urban landscape of Riyadh
  • Encourage citizens of Riyadh to adopt a healthy lifestyle
  • Preserve natural zones and improve the biological diversity
  • Improve quality of life and promote Riyadh’s position among the world’s top livable cities.
  • Yield about SAR 71 billion as ROI 2030, through less healthcare expenses, lower electricity consumption, higher real estate value and use of treated wastewater as a replacement for potable water for irrigation.
  • Create new investment opportunities for the private sector in many sectors and businesses including: nurseries, horticultures works, afforestation, landscaping and irrigation.
  • Contribute to fulfilling a key goal of the Saudi Vision 2030 to achieve environmental sustainability, build a vital community, and improve economic efficiency across the city sectors
  • Achieve some of National Transformation Program goals, including: increasing the green spaces, reducing water waste, improving flood drainage network efficiency, and better utilization of treated wastewater.
  • Achieve the goals of “Quality of Life program” by creating open areas for socializing, practicing and walking.
