Green Riyadh Project

Green Riyadh project is one of the most ambitious urban forestation projects in the world. It 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 will contribute to increasing the per capita share of green space, and raise the total green spaces by planting trees around all city features and facilities as well as in all its provinces. All of the greenings will be watered by recycled water from an irrigation network. The greening initiative will lead to improved air quality and reduced temperatures in the city. As a consequence, this project will encourage Riyadh citizens to follow a healthy lifestyle which is part of the Kingdom’s Vision 2030.


Project Elements


  • Planting 7.5 million trees across the capital as follows:
    • 3,330 neighborhood gardens

    • 2,000 car parking sites
    • 1,670 public facilities
    • 390 healthcare facilities
    • 64 universities and collages
    • 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



Tree species

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