Saudi ministry promotes tree planting to combat summer heat and absorb CO2

Saudi Arabia's Ministry of Environment, Water and Agriculture is urging tree planting as a natural way to reduce summer heat. Trees provide shade, cool urban areas through transpiration, and each tree can absorb about 150 kilograms of carbon dioxide per year. The ministry also highlights benefits like better air quality, reduced noise, and support for wildlife. The ministry advises planting native species that need less water and using drip irrigation to cut evaporation. Applying organic mulch helps retain soil moisture. The goal is to expand green spaces as a long-term investment in the environment, with community participation seen as essential for success.

Tree planting for urban cooling and carbon capture is a solid low tech option. But 150 kg per tree per year sounds like a rough average. Would be good to know which species they are using and the survival rate in Saudi's climate.

The article pushes native species and drip irrigation. That matters because a lot of tree planting projects fail when water demand is too high. If they can keep mortality low, this could actually scale.

Urban heat island reduction is real. But the CO2 number is a headline grabber. Actual sequestration depends on tree maturity, soil conditions, and whether the wood is left to decompose. Still, shade alone cuts AC load, which helps the grid.

Saudi has the Saudi Green Initiative targeting 10 billion trees. This ministry statement fits that narrative. But turning policy into planted and surviving trees is the hard part. Funding and maintenance are where most programs fall short.

The ministry is framing this as a community effort and a long term investment. That is fine for awareness. But without a carbon credit or subsidy mechanism, individual households have little incentive to plant and maintain trees. Policy needs to match the rhetoric.
