This publication is timely as the United ³Ô¹ÏÍøÕ¾ Environmental Program (UNEP) has convened an intergovernmental negotiating committee (INC) to develop an international legally binding agreement on SUPP use by the end of 2024.
SUPP are widely used in aviation due to their strength, lightness, and ability to meet safety and security regulations. However, the airline sector faces challenges associated with improved cabin waste performance and the replacement of SUPP with sustainable alternatives. In addition, airlines face technical and operational obstacles, and the lack of harmonized and risk-based regulations presents a significant barrier to improving recycling and circularity of waste management. The absence of smart regulation continues to constrain airline efforts to improve the sustainability of cabin operations.
Collaboration across the aviation value chain is vital to enable the adoption of circular economy principles and to facilitate the reduction and replacement of SUPP that is necessary for reducing waste and increasing material recovery.
The report advocates for a sectoral approach to managing SUPP in aviation with a clear set of recommendations. Key recommendations include:
For airlines:
- Reduce waste at source by reviewing standards and procedures through the lens of waste reduction and reuse, and professionally assess the need for SUPP. Set clear targets for the elimination, measurement, and tracking implementation, and disclose progress.
- Introduce reusable items as a strategy to drive circularity. This requires logistical changes that incorporate a closed-loop service, including the impact of potential added weight of reusables on aircraft on fuel burn and carbon emissions.
- Improve waste management and recovery by facilitating onboard and ground waste segregation, and undertaking waste composition audits for passenger and cargo operations.
For regulators:
- Proactively encourage the minimization of SUPP by addressing the need for simple harmonized regulations and legislation. Develop guidance that allows for global common definitions and standards for alternative products that include labelling, integrity and certifications.
- Create the infrastructure and frameworks that will make reuse models possible, while being aware of and responsive to the characteristics of international airline operations.
- Endorse a clear methodology and the sharing of good practices as essential to ensuring that segregation processes are efficient and effective.
- Support the development of infrastructure for waste segregation and recovery at or close to airport premises.
For the supply chain:
- Take part in or organize solution-focused discussions involving key stakeholders, to help identify and implement process changes that prioritize end-to-end solutions that ensure best practices and promote regulatory change.
- Increase public/private sector collaboration and significant investments to implement circular economy principles in the airline sector value chain to enable considerable changes to processes and procedures for stakeholders both upstream and downstream.
“Airlines are taking a comprehensive approach to sustainability that includes addressing the environmental impact of SUPP. The recommendations of this report will help airlines, regulators and the supply chain to manage the complexities of reducing SUPP. This includes finding alternatives to SUPP, creating a harmonized regulatory framework, and promoting sector-wide collaboration. Importantly, these recommendations take advantage of the expertise of all participants in the aviation sector to develop, adapt and implement the solutions best suited to an aircraft’s unique environment,” said Marie Owens Thomsen, IATA SVP Sustainability and Chief Economist.
The IATA passenger insights survey conducted in November 2023 showed that more than three quarters of passengers would feel better about flying if it did not involve any SUPP, and that they would be happy to support fewer food and beverage options so that airlines could achieve this. The IATA Shipper Survey 2022 showed that 50% of cargo customers include waste reduction along the supply chain among their top priorities and cargo operators are receiving requests from end customers to reduce the associated plastic packaging and wrapping.
