The Global Round for the inaugural International Environmental Coding Competition (IECC) 2025 recently concluded, celebrating innovative and creative tech solutions from young innovators to decode the environmental threats of today. Presented by Geneco, Marshall Cavendish Education (MCE) and Koding Next co-organised this year’s IECC, which tackled two United Nations Sustainable Development Goals: Goals 13 Climate Action and 15 Life on Land. Participants were given the opportunity to choose which goal to work on and develop innovative coding solutions that can address environmental challenges and promote sustainability. Geneco also pledged a $10,000 donation to the coral reef conservation efforts by NParks’ Garden City Fund — highlighting how youth innovation can meaningfully drive awareness and inspire environmental action.
Through Roblox and Scratch’s coding platforms, young coders from around the world worked on harnessing technology to decode and create a positive impact on the climate goals chosen.
240 participants worldwide competed in the preliminary rounds and 37 individuals emerged as finalists for the Global Round in Singapore. IECC saw young individuals from Bangladesh, India, Indonesia, Jordon, Macau China, Philippines, Saudi Arabia, Singapore, Thailand, United Arab Emirates and Vietnam.
This competition highlights a necessary partnership that champions innovation, learning, and sustainability. It further strengthens the bridge between education and real-world environmental advocacy.
Overall Scratch Winner: Gideon Immanuel Salim, Thailand
The Winning Game
The Green Horizon: Regenesis
Gideon created two minigames – an eco-city building minigame and a minigame that takes place in a forest. The first game, the eco-city minigame, shows how AI can help to build entire eco-cities by making a blueprint and giving recommendations on eco-asset usage.
The second minigame takes place in a forest where players restore deformed trees. It's made with a real natural-language-based AI (Text classifier) to help the player diagnose what’s wrong with the trees.
Overall Roblox Winner: Tengku Hamza Bin Tengku Mohd Uzaini, Malaysia
The Winning Code
Tengku Hamza’s proposal, the Heat Control Simulator, provides an interactive single-player Roblox experience that demonstrates how AI can guide sustainable urban planning to reduce Urban Heat Island (UHI) effects.
“The game focuses on analysing zone-based temperature data, simulating AI-driven recommendations, and encouraging players to make environmentally responsible decisions. It reflects the core ideas of SDG 13: Climate Action and SDG 15: Life on Land through gameplay that teaches players how nature-based solutions and city design choices influence temperature and environmental health,” said Tengku Hamza Bin Tengku Mohd Uzaini.
