Split Emerges Over Scope 3’s Impact On Aftermarket Teardown Economics

As aviation leaders met in Montreal for ICAO Aviation Climate Week earlier this month to discuss how the industry can reach net zero, a separate debate is emerging in the aftermarket over whether Scope 3 emissions reporting and circular economy pressures are already changing maintenance and teardown economics, or whether the sector is still only getting ready for a shift that has yet to fully take hold.

Across the aftermarket, executives are describing a slow shift away from a linear “use-and-dispose” approach toward multicycle use of assets, with used serviceable material (USM), higher repair activity and more efficient teardown processes becoming more firmly embedded in strategy.

“Scope 3 pressures are driving a fundamental shift in how aviation assets are managed across their life cycle,” Simon Bayliss, chief operating officer at AerFin, tells Aviation Week. “The industry is moving away from a single life-cycle mindset toward a more circular, multicycle approach focused on reuse, repair and life extension.”

He adds that life-cycle accountability is already strengthening teardown dynamics. “Greater focus on life-cycle accountability is accelerating demand for USM and repair-first strategies, with teardown economics strengthening as more components successfully reenter the supply chain,” says Bayliss.

At the same time, he notes that circularity is beginning to influence earlier-stage decisions, including design for disassembly, recoverability and long-term reuse potential.

However, not all stakeholders see immediate economic transformation. GA Telesis CEO Abdol Moabery says Scope 3 considerations are still largely in their early commercial phase. “At this stage, they have not yet materially altered the core economics of maintenance or teardown decisions,” he says. “Those decisions today are still primarily driven by traditional factors such as cost, availability and turnaround time.” Even so, he acknowledges a directional shift, with life-cycle accountability increasingly shaping how airlines, OEMs and investors are focused on life-cycle impact accountability.

Pascal Parant, chief commercial and marketing officer at Vallair Group, points to a gradual reframing of USM economics under sustainability pressure. He says a more holistic approach, shaped by Scope 3 pressures and circular economy thinking, will improve the optimization and value of USM. It also strengthens the move away from a purely transactional teardown model toward one based on life-cycle value, he says.

From the manufacturing side, ATR highlights how Scope 3 exposure is already embedded in design priorities, noting that aircraft use accounts for more than 90% of its footprint. The company emphasizes fuel efficiency, weight reduction and performance improvements as primary levers.

“Scope 3 thinking shapes material selection and maintenance strategies: lighter materials to reduce fuel burn, durable components to limit spare parts flows and modular designs where feasible to simplify maintenance operations,” ATR states.

While ATR is not the design authority for major structural components, which are developed by partners such as Leonardo, Airbus Atlantic or Safran, the airframer says it incorporates eco-design requirements, assessments and supplier discussions to ensure environmental criteria are considered wherever it has influence.

As the industry reflects on the wider climate debate, the divide elsewhere over Scope 3’s near-term impact is becoming clearer. Whether the economic shift happens gradually or quickly, few now doubt that life-cycle accountability is moving from a side issue to a central factor in the aftermarket’s long-term planning.
