A global stage for sustainable transformation
Expo 2025 in Osaka emerges as a milestone event in the international pursuit of sustainability, placing the United Nations Sustainable Development Goals (SDGs) at its core.
As countries face escalating environmental crises, this world exposition provides a vital platform to accelerate progress on global challenges such as climate change, resource scarcity, and social inequality. By spotlighting pioneering technologies and collaborative approaches, Expo 2025 serves not only as a showcase of innovation but also as a catalyst for long-term transformation.
Analytical insight into sustainable innovation
Expo 2025 features an array of groundbreaking initiatives aimed at advancing the circular economy, reducing carbon emissions, and enhancing biodiversity. With more than 150 countries participating, the event demonstrates an integrated approach to solving the world's most urgent issues.
The Germany Pavilion, themed “Wa! Germany”, exemplifies this ethos by using biodegradable materials such as mycelium and bio-based plastics, reflecting a deep commitment to material circularity. According to the Ellen MacArthur Foundation, adopting circular practices could reduce global greenhouse gas emissions by 45%.
In addition, the Co-Design Challenge fosters practical, scalable solutions including SHELLMET—a durable helmet made from recycled scallop shells—and edish, a fully compostable tableware product designed to become fertiliser after use. These innovations embody the principles of SDG 12 – Responsible Consumption and Production, promoting lifecycle thinking and waste valorisation.
Addressing ocean health and climate resilience
The Blue Ocean Dome draws attention to the critical state of marine ecosystems. With over 11 million tonnes of plastic entering the ocean annually, according to UNEP, pavilions like this one are instrumental in educating the public and advocating for change.
Scheduled events during the “Future of Earth and Biodiversity” theme week (17–28 September) will focus on decarbonisation, climate mitigation, and forest regeneration—core themes of SDG 13 – Climate Action and SDG 15 – Life on Land.
Clean energy at the forefront
Energy efficiency and carbon neutrality are key themes of Expo 2025. The use of perovskite solar cells, which are lighter and more flexible than traditional panels, demonstrates cutting-edge advances in renewable energy. The introduction of carbon recycling, using hydrogen and biogas to produce synthetic methane, along with Direct Air Capture (DAC) technologies, aligns with targets set in SDG 7 – Affordable and Clean Energy. These developments indicate the feasibility of scalable solutions to reduce dependence on fossil fuels and achieve net-zero emissions by mid-century.
Global collaboration and education for sustainability
The United Nations Pavilion, uniting 35 UN agencies, represents a unique educational effort aimed at raising awareness of the SDGs across diverse audiences. Through interactive exhibits and panel discussions, it reinforces the role of global governance in sustainable development. The Cartier Women’s Pavilion, designed with recycled materials, further underscores the link between gender equality (SDG 5) and environmental resilience, showcasing women's contributions to a more equitable and sustainable world.
Long-term legacy through participation and innovation
Initiatives like the Seeds for the Future Pavilion by Sumitomo invite visitors to co-design sustainable futures, leveraging AI and digital platforms for participatory development. Similarly, the Better Co-Being Festival encourages students and businesses to model healthier societies, aligning with SDG 3 – Good Health and Well-being and SDG 11 – Sustainable Cities and Communities.
The legacy of Expo 2025 lies not only in its innovations but in its potential to inspire systemic change. Through these participatory projects, it nurtures a culture of collaboration, critical for advancing the Global Society and ensuring inclusive progress for generations to come.
Expo 2025 Osaka stands as a beacon of international cooperation, innovation, and commitment to the Sustainable Development Goals. Its wide-ranging initiatives—from circular design to clean energy—demonstrate what is achievable when governments, industries, and citizens align efforts. As the world seeks actionable strategies to combat climate change and social inequities, platforms like Expo 2025 play a crucial role in fostering hope and momentum.
