Carbon Footprint of Large-Scale Academic Gatherings: Insights from the Suranaree Agricultural Fair 2025

Researchers from the School of Environmental Engineering have conducted an in-depth study on the carbon footprint of the Suranaree Agricultural Fair 2025, a nine-day public event held in Nakhon Ratchasima Province, Thailand. The event, promoting sustainable agricultural innovation and the Bio-Circular-Green Economy, attracted 258,917 participants and was spread over 226,068.19 square meters. The study aimed to assess the environmental impacts of large-scale academic gatherings, identify major sources of greenhouse gas emissions, and propose opportunities for emission reduction.

Key Takeaways:

• The total carbon footprint of the event was estimated at 1,524,844.09 kilograms of carbon dioxide equivalent, with an average emission of 5.89 kilograms per person.
• Food consumption and participant travel were the primary contributors to the total emissions, accounting for more than 67 percent of the total emissions.
• Emission patterns were analyzed across different participant groups, revealing varying behaviors and engagement levels that influence carbon emission results.
• The study demonstrates the significant environmental impact of large-scale academic fairs and provides a foundational dataset for ongoing emissions monitoring.
• The research offers targeted recommendations to enhance data collection, promote low-carbon practices, and support institutional efforts toward achieving carbon neutrality.
• The study contributes to integrating sustainability principles into event management within the higher education sector.

Statistics:

• The event was attended by 258,917 participants.
• The event was held across an area of 226,068.19 square meters.
• The total carbon footprint of the event was estimated at 1,524,844.09 kilograms of carbon dioxide equivalent.
• Food consumption and participant travel accounted for more than 67 percent of the total emissions.
• The average emission per person was 5.89 kilograms.
• Emissions averaged 6.74 kilograms per square meter and 14,115.19 kilograms per hour of the event.
