Chulalongkorn turns carbon learning into a card game

Chulalongkorn University has launched Every Day CO₂ Challenge, a bilingual card game that teaches life cycle assessment and carbon footprints through play. The project aims to make environmental decision-making easier to understand for students, professionals and the public.

Why it matters: - Every Day CO₂ Challenge gives learners a simpler way to understand carbon footprints and Life Cycle Assessment, a framework used to measure environmental impacts across a product’s life cycle. - The game is designed to turn a difficult technical topic into an active learning experience that can work for both classrooms and public audiences. - The project reflects a wider shift toward hands-on learning at a time when instant AI answers can reduce opportunities for discussion and deeper understanding.

What happened: - Varoon Varanyanond, Industrial Partnership Advisor at the Center of Excellence on Petrochemical and Materials Technology at Chulalongkorn University, developed the card game after conventional lectures and presentations failed to make LCA easy to grasp. - The game was created under the MA-RE DESIGN project with support from GIZ (Deutsche Gesellschaft für Internationale Zusammenarbeit). - Chulalongkorn University presented the game as a new way of learning environmental concepts.

The details: - Every Day CO₂ Challenge asks players to collect cards with the lowest total environmental impact score. - Action Cards add surprise and strategy to the game. - A Game Master prompts players to explain their choices and think through the environmental consequences. - The game is built for elementary school students through adults. - Players are pushed to compare materials, manufacturing methods, transportation choices and disposal options. - The early paper prototype has grown into 50 bilingual Thai-English game sets made from recycled plastic. - The Thai Packaging Design Association and GIZ supported that development. - The game has been tested with students, educators, business professionals and members of the public. - Feedback from those tests was described as highly positive. - Read more at Chulalongkorn University.

Between the lines: - Varoon Varanyanond’s approach suggests that environmental literacy may improve when people are asked to reason through tradeoffs instead of memorizing definitions. - The game’s design puts curiosity at the center, with players learning by asking why one product scores worse than another or why transport choices affect emissions differently. - The recycled-plastic game sets also reinforce the message by matching the lesson with the material.

What's next: - Chulalongkorn University is positioning the game as a tool that can keep expanding beyond its initial test groups. - The strongest signal of future impact will be whether the game continues to move from prototype to wider classroom, professional and public use.

The bottom line: - Chulalongkorn University is betting that a game can teach climate concepts more effectively than a lecture, and early response suggests the approach may travel well beyond campus.
