IATA and ASF are Developing a Cabin Waste Composition Audit Program

The International Air Transport Association (IATA) and the Aviation Sustainability Forum (ASF) are collaborating to develop a Standardized Cabin Waste Composition Audit (CWCA) Program.

The CWCA aims to address the issue of cabin and catering waste in the aviation sector. ASF’s Cabin Waste Composition Audit Platform is scheduled to launch in September 2024.

Initial Findings from CWCA Trials

CWCA trials were conducted in two phases, covering 25 flights of varying lengths at Singapore’s Changi Airport in November 2023 and April 2024. Audits, conducted by ASF using a methodology developed by IATA, revealed that the aviation sector produces over 3.6 million metric tonnes of cabin and catering waste annually. Significantly, 65% of this waste is attributed to food and beverages, with untouched meals accounting for 18%.

Audit data is crucial to guide the airline industry and other stakeholders towards waste reduction through reuse and recycling opportunities. Previous IATA research identified the absence of a standardized methodology for conducting cabin waste audits, resulting in a lack of data for well-informed decision-making. Implementing a standardized audit can address these issues and demonstrate sector progress towards waste reduction.

Why Reduce Cabin Waste?

Reducing cabin waste is not just a sustainability goal but also a financial necessity for airlines. Efficient waste management can lead to cost savings related to waste disposal and resource management. Additionally, reducing onboard waste enhances the airline’s image and meets increasing passenger expectations for environmentally responsible travel. This proactive approach can also ensure compliance with stricter environmental regulations that may emerge as global attention on sustainability grows.

The impact of cabin waste extends beyond the aviation industry and significantly affects ecosystems. Improper waste management can contribute to pollution and harm wildlife, especially when waste ends up in landfills or oceans. By reducing cabin waste, airlines can minimize their environmental footprint and contribute to the health of global ecosystems. This effort supports broader environmental goals, such as reducing carbon emissions and conserving natural resources, ultimately leading to a more sustainable future.
