Earth Day, observed annually on April 22, is a global moment to reflect on our collective responsibility to protect the planet. In 2026, as Earth Day marks its 56th anniversary under the theme “Our Power, Our Planet,” the focus underscores the importance of collective action in driving progress.
The theme signifies the urgent need to accelerate the transition to renewable energy and significantly scale global clean electricity generation by 2030. Transitioning to clean energy is critical—not only for addressing climate change, but also for strengthening economies, supporting societal well-being, and safeguarding natural systems to build a more resilient and sustainable future.
This global momentum is closely aligned with national priorities in the Kingdom of Saudi Arabia. Under Saudi Vision 2030, the Kingdom is advancing an ambitious energy transition, with a target to reach around 50% of its electricity generation from renewable sources by 2030. At KAUST, raising awareness and enabling action remain central to this transition.
As part of this year’s Earth Day activities, the KAUST community is invited to engage with a range of initiatives that encourage reflection on environmental responsibility, including a dedicated talk exploring the role of renewable energy within the global sustainability transition. These activities are part of KAUST’s broader educational outreach for local communities, offering programmes to learn about clean energy, energy efficiency, and good water management through interactive sessions and facility visits.
By tapping into this collective potential, KAUST aims to empower its community to reflect on individual and institutional environmental footprints while contributing to a shared pathway toward sustainability.
Join thousands around the world as we harness our power to protect our planet.
Sustainability Seminar: History and Evolution of Batteries: A 2000-Year History of Human Creativity and Innovation
Date: April 22
Time: 10:30am to 12 pm
Venue: Auditorium between Bldgs 4 and 5
KAUST Desalination Plant Open House
Time: 10:00 – 11:00 a.m.
Registration: Sign up here to join the tour
Join an exclusive guided tour of the KAUST Seawater Desalination Plant, organized by the Campus and Community team in collaboration with Students for Sustainability. This state-of-the-art facility produces up to 50,000 m³ of potable water per day using seawater reverse osmosis (SWRO) technology, ensuring a reliable and high-quality water supply for the KAUST community.
The tour will provide an in-depth look at the desalination process, from seawater intake and pre-treatment to high-pressure pumping, membrane filtration, and final storage. Participants will gain insight into how advanced technologies enable efficient water production, reduce environmental impact, and support sustainable water management in an arid environment.
KAUST Wastewater Treatment Plant Open House
Time: 2:00– 3:00 p.m.
Registration: Sign up here to join the tour
Join an exclusive guided tour of the KAUST Wastewater Treatment Plant (WWTP), organized by the Campus and Community team in collaboration with Students for Sustainability. This state-of-the-art facility treats approximately 11,500 m³ of wastewater daily using advanced membrane bioreactor technology, producing high-quality treated effluent that meets World Health Organization (WHO) and international standards.
The tour will offer an in-depth look at key stages of the treatment process, including filtration, biological treatment, and final purification. Participants will gain insight into how these advanced systems enable safe water reuse, reduce environmental impact, and support biodiversity. The visit will also highlight the critical role of wastewater management in protecting natural systems, sustaining the water cycle, and strengthening resilience in water-scarce regions.
Skate Park Green Stewardship activity
Date: April 22
Time: 5:00 – 6:30 p.m.
Venue: Skate Park
This family-friendly activity at the Skate Park is designed to foster environmental awareness among young users and their families. Observations have shown that surrounding greenery can be unintentionally damaged, often due to limited awareness of the time, care, and resources required to grow and maintain plants in KAUST’s unique environment. The activity aims to build understanding and encourage more mindful interaction with natural spaces.
The session will begin with an interactive storytelling segment introducing children to the “life of a tree” in KAUST, highlighting the role of trees in providing shade, oxygen, and habitats, as well as the long-term care required for their growth. This will be followed by a guided community planting activity, where participants will plant resilient saplings or shrubs within the Skate Park area alongside subject matter experts, fostering a sense of responsibility and connection to the landscape.A brief demonstration will also introduce simple practices for engaging respectfully with green spaces while using recreational areas
Community Garage Sale | A Reuse Initiative
Date: April 23
Time: 5:00 p.m. to 8:00 p.m.
Venue: Discovery Square
Join us for the Community Garage Sale at Discovery Square on Thursday, April 23, from
This event aims to promote reuse, reduce waste, and encourage sustainable living within our community. It is a great opportunity to give useful pre-loved items a second life, connect with neighbors, and support a more sustainable lifestyle.
Community members who would like to participate as sellers and are committed to attending, are invited to register through the seller registration form before April 20. For mpore details, contact recycle@kaust.edu.sa.
Waste-to-Cooling Innovation Talk
Time: 02:00– 03:00 p.m.
Venue: Bldg 16, Room 2206
Join us for a 30-minute presentation introducing a pioneering start-up advancing waste-to-cooling technology in the Kingdom. This innovative solution addresses two critical environmental challenges—construction and mining waste, and the high energy and water demands of agricultural cooling—through an integrated and resource-efficient approach.
The concept transforms waste rocks into engineered thermal energy storage systems that capture cool night air and release it during the day to regulate greenhouse temperatures. By leveraging passive cooling principles, the system operates with zero water use and significantly lower electricity requirements compared to conventional cooling methods.
This session will explore how such innovations can contribute to more sustainable agricultural practices, reduce environmental impact, and support long-term resource efficiency in arid regions.
Debate on Sustainable Energy
Students will gather on April 21, from 12 to 1pm at Bldg 18, Fellowship Halls for a preparatory session focused on the vocabulary related to the energy sector, supporting the development of clear and effective argumentation. Organized by the Students for Sustainability with the support of the KAUST English Language Program, the session will equip participants with key terms and concepts to engage more confidently in structured discussions.
This session will be followed by a student debate on sustainable energy, taking place on April 28, where participants will apply the vocabulary and perspectives developed during the workshop.
