Simplify's Take

What believers are saying

  • Riyadh's Green Program gives PLANET a flagship mandate and global reference client.
  • Five pilot districts create follow-on implementation work if 2027 testing delivers measurable cooling.
  • Saudi Arabia's climate spending validates PLANET's sustainability consulting narrative for public-sector buyers.

What critics are saying

  • Riyadh dominates PLANET's 2026 visibility; one missed milestone damages future GCC bids.
  • The 12-month RCRC study ends in 2027; weak findings kill implementation momentum.
  • Public procurement delays in Greece and Saudi Arabia stretch cash flow and constrain hiring.

What makes PLANET unique

  • RCRC selected PLANET on May 14, 2026, for Riyadh's citywide cooling strategy.
  • Devex lists 15 awarded contracts, showing repeatable public-sector execution across markets.
  • PLANET blends enterprise architecture discipline with advisory work on urban systems and infrastructure.

RCRC appoints PLANET to lead Riyadh cooling project.

RCRC appoints PLANET to lead Riyadh cooling project. The Royal Commission for Riyadh City (RCRC) appointed PLANET as the lead consultant for the Riyadh Strategic Cooling Project, an initiative aimed at addressing urban heat challenges in the Saudi capital. Implemented under the Riyadh Green Program, the project includes developing a citywide cooling strategy, preparing urban planning and building materials guidelines, and identifying five pilot zones to test innovative cooling solutions, PLANET said in a statement. PLANET said the project aligns with the Saudi climate transition efforts, including the Saudi Green Initiative, which supports large-scale environmental and sustainability investments across the Kingdom. Over 12 months, the project will provide a framework to assess Riyadh's heat challenges and a roadmap to reduce urban temperatures through data-driven analysis, sustainable planning, and resilient infrastructure practices. Beyond its local impact, the company expects the initiative to become a global benchmark for cities facing rising temperatures driven by climate change.
