The World Expo in Osaka officially concluded in October 2025 after six months of events, projects, installations, and over 28 million visitors. One of the core themes was sustainability: circular economy, clean mobility, innovative materials, and strategies for carbon neutrality.

This article provides a summary of the key green innovations that characterized the event and its concrete legacy for companies, designers, and operators in asset-based sectors.

The Expo’s “green” strategy: an integrated and measurable approach

Before opening, the organizers adopted ISO 20121 for sustainable events, committing to reducing emissions, waste, and energy consumption.

Throughout the six months of the exhibition, this strategy translated into:

systematic reduction of single-use materials
circular waste management
modular constructions designed for disassembly and reuse
focus on emissions across the entire supply chain

The strategic framework was defined in the official sustainability documents published on the Expo website (2022–2025), including periodic reports and environmental assessments.

Circular economy: the strongest innovation of the Expo

One of the most widely discussed elements following the Expo’s closure was the success of the reuse, recycling, and repurposing program for structures.

The circular market “MYAKU-ICHI!”

At the end of the event, the organization launched the platform:

EXPO CIRCULAR MARKET MYAKU-ICHI!

where companies and institutions could purchase dismantled components from the pavilions, panels, furnishings, and reusable technical materials.

According to data published in November 2025, over 70% of the qualified materials were reintegrated into new public and private projects.

The Grand Ring: symbol of circular construction

The large circular wooden structure, 12 meters high and 2 kilometers long, was designed to be dismantled and reused.

90% of its wooden modules have already been allocated to urban and educational projects in the Osaka and Hyogo prefectures.

Sustainable materials: design for “second use”

One of the most impactful legacies of the Expo is the practical demonstration that innovative materials and modular design can drastically reduce environmental impact.

The most relevant technologies showcased in Osaka:

Locally sourced laminated wood (cedar and cryptomeria) for pavilions and walkways
Recyclable high-tech membranes for lightweight roofing
Dismountable prefabricated elements to reduce demolition waste
Bio-composite panels used across various thematic pavilions

According to data released after the closure, the entire site achieved a 30% reduction in the use of high CO₂ footprint materials compared to previous Expos.

Clean energy and electric mobility: the city as a laboratory

The Expo featured the “Green Expo” section, dedicated to technologies for carbon neutrality. The post-event review reveals significant outcomes.

Energy and innovation (NEDO Green Innovation Fund)

NEDO presented projects tested with real users:

low-impact electrical systems for temporary buildings
solutions for green hydrogen production
low-carbon construction materials
energy-sharing systems between pavilions

Smart mobility and sustainable flows

Internal mobility was managed using:

electric vehicles for visitors
autonomous shuttles
internal cycling network
real-time air quality monitoring systems
At the close of the event, 93% of all movements within the Expo area were recorded as having zero direct emissions.

The value of international collaboration: SDGs and cultural innovation

National pavilions integrated educational and cultural programs focused on sustainability.

Among the most significant:

UN Pavilion, leading SDG initiatives
joint projects between Japanese universities and European institutions
interactive activities for science communication
events focused on circular economy, biodiversity, and climate resilience

In its October 2025 statement, the United Nations highlighted Expo Osaka as “one of the most innovative global projects dedicated to sustainability in the SDG decade.”

The green legacy: what remains after the Expo’s closure

The legacy of the Exhibition can be identified in three main areas:

1) Urban regeneration of Yumeshima

The area will be transformed into a district dedicated to innovation, sustainable tourism, and smart mobility.

2) Reuse of materials and waste reduction

Recycling goals were exceeded: over 75% of materials have already been allocated to new projects.

3) Replicable models for cities and businesses

The Expo demonstrated how to integrate:

modular design
green supply chains
low-carbon technologies
zero-emission electric mobility

For professionals in real estate, industry, and technical asset management, the legacy of the Expo represents a concrete reference for developing long-term sustainable projects.

Expo Osaka 2025 was a global laboratory of environmental innovation. Concluded in October, the event left behind a set of replicable strategies: modular and reusable construction, electric mobility, clean energy, and a circular economy model that proved viable on a large scale.

For businesses, investors, and asset operators, the solutions showcased in Osaka indicate the future direction of sustainability: efficiency, circularity, and design geared toward reuse.
