Green Exhibitions: From Optional to Mandatory — The Road to National Standards for Zero-Carbon Booths and Modular Construction

What is left behind when a major exhibition closes? Under the traditional construction model, the answer is piles of single-use waste. Take the Canton Fair, known as "China's No. 1 Fair," as an example: a single edition once generated over 2,500 tons of construction material waste — roughly equivalent to 50 percent of Guangzhou's total daily household waste. Such waste typically contains nails and coatings, is difficult to recycle, and can only be incinerated, releasing harmful gases such as formaldehyde from paints and adhesives.

These figures mark the starting point of China's exhibition industry's green transformation.

A decade-long transformation. In 2014, under the guidance of the Ministry of Commerce, the China Foreign Trade Centre launched the Canton Fair Green Development Plan, with green custom booth construction as the breakthrough. After three years and six editions, the 120th Canton Fair (2016) achieved its goal of a "100 percent green booth penetration rate" on schedule. The subsequent Canton Fair Green Development Plan 2.0 extended the green concept from "switching materials" to upgrading design philosophy and full-process management.

From corporate practice to national standards. Greater value lies in distilling experience into replicable standards. The Guide for Green Booth Evaluation and the Basic Requirements for Safety Management of Exhibition Venues were released at the end of 2021 and took effect on July 1, 2022, while the Guide for Green Exhibition Operation was released and implemented in March 2023. The three standards address, respectively, "how a single booth becomes green," "how an entire exhibition becomes green," and the safety bottom line. The Guide for Green Booth Evaluation defined, for the first time, the "3R" principles and evaluation indicators for green booths, giving "what counts as a green booth" a quantifiable yardstick. New standards, including the Guide for the Implementation of Green Exhibition Floor Covering, are now under development.

The efficiency equation of green construction. Whether green practices can be widely adopted depends on whether they follow market logic. Research shows that while the initial cost of eco-friendly materials may be slightly higher than traditional wood, large exhibitions typically have a fixed exhibitor ratio of 70 to 80 percent. Because modular exhibits can be disassembled, stored and reused, the overall cost falls below that of single-use wood after more than two uses. At the same time, standardized components improve construction efficiency, reduce on-site fabrication and lower safety risks — making green construction not merely an environmental issue but a lever for improving quality and efficiency across the industry.

Trends and actions. Following the example of benchmark events such as the Canton Fair, shows and venues including the CIIE and the National Exhibition and Convention Center (Tianjin) have adopted this green standard system. This edition of the Canton Fair further expanded the promotion of modular construction, setting up a modular construction pilot zone, increasing the number of modular construction service providers to eight, and restricting the amount of wood used in mixed-profile custom booths.

For exhibitors, this means booth concepts need to factor in "recyclability" earlier: prioritizing dismountable structures such as aluminum profiles, splitting graphics and shapes into replaceable modules, and reusing the same core structure across multi-city tours. Green is not an added cost — it is a component of long-term exhibition efficiency.
