A vibrant online English platform, 51Talk, recently allowed children from the Middle East and Southeast Asia to voice their ideas at COP30 in Belém, Brazil, from November 15 to 21, 2025. The initiative, which started in 2023, gives young learners from countries like Saudi Arabia, UAE, Turkey, Thailand, and Vietnam a chance to share their thoughts on climate and environmental issues in English.
During the conference, students not only spoke about their local experiences but also gained hands-on insights into biodiversity through rainforest explorations and cultural activities. These experiences helped them see how sustainability and language learning can intertwine. This unique approach connects classroom learning with real-world challenges.
The program, called GreenTalk: Speak for Future, shows 51Talk’s commitment to using language as a tool for global engagement. The platform focuses on personalized 1-on-1 lessons that promote confidence and skill in public speaking.
Jack Huang, CEO of 51Talk, emphasizes the importance of empowering children. He stated, “Every child should be able to share their views with the world.” This initiative not only builds language skills but also nurtures empathy and understanding of global issues.
One standout participant was eleven-year-old Le Bao Nhi from Vietnam. Initially struggling with English, she now confidently speaks about her local beach’s plastic pollution and her efforts to organize clean-ups. Her story highlights how even small individual actions can spark change.
Students at COP30 displayed not only improved English but also remarkable confidence and the ability to link local concerns to broader global challenges. This platform enables young voices to participate actively in international conversations, fostering connections across cultures and generations.
According to a recent survey by UNESCO, nearly 90% of parents believe that learning English boosts their children’s opportunities in the globalized world. This reflects a growing trend where language skills are seen as essential for young people today.
With over 40 million learners in 50+ countries, 51Talk continues to shape the next generation’s ability to communicate effectively and confidently on the world stage. For more information about this impactful program, visit 51Talk.
