In support of commercial aviation’s path toward net zero carbon emissions, Boeing has announced the Boeing Cascade Climate Impact Model for public use.
Cascade, a data modeling tool that identifies the effects of a range of sustainability solutions to reduce aviation’s carbon emissions, is accessible on Boeing’s new Sustainable Aerospace Together hub, www.sustainabilitytogether.aero.
Cascade examines the full life cycle of alternate energy sources for aviation – from production through distribution and use – and quantifies the ability to cut aviation’s carbon emissions. Data modelling also measures aeroplane fleet renewal, operational efficiency, renewable energy sources, future aircraft and market-based measures as pathways to decarbonisation.
“We created Cascade to serve as an industry tool that creates a common framework among aviation, energy, finance and policy,” said Boeing Chief Sustainability Officer Chris Raymond. “By putting data first and sharing this model with the public, we are enabling collaboration, feedback and alignment across industry, government and others who work together to achieve a more sustainable aerospace future.”
Key findings from Cascade’s assessments include:
- The journey to net zero is dependent on the overall energy transition. Whether using sustainable aviation fuel (SAF), hydrogen or electricity, the energy and emissions associated with the production, distribution and storage of fuels must be minimized to achieve the most sustainable outcome.
SAF will be the biggest contributor to reducing carbon emissions because it can be used in commercial airplanes flying today – both new and old. Since many jets flying today will be in service into and even beyond the 2040s, it is imperative to abate their emissions with SAF.
While electric- and potentially hydrogen-powered aircraft will emerge in future decades, their contribution to emissions reduction will likely be limited through 2050 due to long timeframes for development and deployment and the magnitude of related infrastructure changes for airports and pipelines.
Renewing fleets with best-in-class, fuel-efficient airplanes will significantly reduce emissions in coming years.
“Cascade helps airline operators, industry partners and policymakers see when, where and how different fuel sources affect their sustainability goals,” said Neil Titchener, Cascade Programme Leader.
“Our industry has really hard questions ahead of us, we’re going to have to make difficult choices. Cascade can be the conversation starter for how each decarbonization pathway can help us reach a more sustainable future.”
