Sustainability is an integral element of AIPH Horticultural Expos and part of AIPH philosophy.

Expo planning and preparation requires the Expo organizer to think of the Expo legacy and find sustainable solutions for the further use of the Expo park, infrastructure and support of the created immaterial legacies.

These requirements are reflected in our Expo Regulations and supported by our Green City research. Through our Green City initiative, we promote the essential role of plants in creating vibrant urban areas in which people and businesses can thrive. Our environment, human wellbeing, social cohesion and economies are all improved by intelligently designed green space.

These developments support AIPH’s commitment to encourage the Expo organizers and contribute to the implementation of the United Nations 2030 Sustainable Development Goals.​

Amongst Sustainability impacts of AIPH Expos are:​

  • Better access to green areas per capita​
  • Increased water, air and soil quality​
  • Protection of biodiversity and threatened species​
  • Land regeneration​
  • Increased number of protected sites​
  • Catalysing climate action through hard and soft infrastructure​

Access to Green Areas​

AIPH expo sites increase the amount of green and public space, often becoming permanent green legacies for host cities. These new green areas enliven the lives of local residents and can attract new tourists from all over the world, often for many years after the AIPH expo is over. ​

Most AIPH expo hosts have proudly kept their expo sites as public parks, gardens or event venues for recreational use and future events. ​

Visiting former AIPH expo sites have become a cultural attraction in many cities and have positively impacted people’s habit of participating in outdoor activities, increasing the overall liveability for all local residents. ​

In Hamamatsu, Japan, 2004 Pacific Flora Expo site became the Hamanako Garden Park, with a total area of 56 ha available to the public. It has significantly increased the population access to green areas in Shizuoka-Hamamatsu, the fifth prefecture of Japan by number of inhabitants (population in 2020 is 2,92 m people)​
