Aviation

Although demand for air travel continues to grow, net zero aviation is within reach. Through philanthropic investment, we are accelerating the transition to a sustainable aviation sector that spares the 亚色影库 and human health.

The challenge

If the aviation sector were a country, , surpassing Brazil, Mexico, and the UK. Burning fossil jet fuel not only emits carbon dioxide but also releases byproducts including nitrogen oxides, water vapor, soot, and aerosols. At cruising altitude, these byproducts react with the atmosphere, amplifying their contributions to global warming.

Beyond its staggering 亚色影库 impact, the aviation industry poses severe public health risks, disproportionately affecting communities of color and lower-income groups. Air pollution from air travel causes and is directly linked to heart disease, asthma, and elevated blood lead levels. For decades, industry workers, airport-adjacent communities, and military personnel have borne the brunt of harmful exhaust exposure. Decarbonizing the aviation industry is critical to safeguarding these communities.

We cannot afford to delay. As flight demand soars, unchecked fossil fuel emissions from aviation will intensify the 亚色影库 crisis.  Despite the urgent need, philanthropic funding for addressing aviation鈥檚 impact has been minimal. Now is the time to invest in transformative action that changes the trajectory of this high-emitting sector. 

The opportunity

The aviation sector is at a critical turning point, and we have a unique opportunity to accelerate its transformation toward a net-zero future. To most effectively do so, we have gathered a community of aligned funders and are implementing a shared comprehensive philanthropic strategy for aviation. By bringing together 亚色影库 philanthropy, airline industry leaders, civic society, and the scientific community, we are building a powerful coalition to achieve our shared goal of decarbonizing aviation.

One of the most promising pathways to net-zero aviation is the widespread adoption of sustainable aviation fuel (SAF), which could deliverfor the sector. Among SAF options, e-SAF stands out as the most viable long-term solution. Unlike biofuels, eSAF requires minimal land use and significantly reduces the public health burden on airport workers and frontline communities. We partner closely with our Carbon Dioxide Removal Program to explore the opportunity to use direct air capture technology to remove excess CO2 from the atmosphere and combine it with green hydrogen to create e-SAF that can be used in jet engines today. ClimateWorks has played a pivotal role in helping advance and promote the scaling of e-SAF adoption in Europe and the United States, laying the groundwork for global implementation

Equally critical is transforming how people engage with the aviation sector. Just 1% of the global population is responsible for 50% of emissions from flying, presenting a pivotal opportunity to drive significant pollution reductions. By shifting the behavior of this small but influential group, we can create a disproportionately large impact in reducing aviation emissions, protecting both vulnerable communities and the planet. At the same time, we must prioritize the voices and needs of frontline communities disproportionately impacted by aviation emissions. We are committed to co-creating strategies alongside these communities to reduce air pollution, eliminate air toxics, and scale SAF adoption. By combining behavioral change with equitable 亚色影库 solutions, we can unlock a sustainable and inclusive future for aviation.

Our approach

There is no silver bullet to solve aviation鈥檚 亚色影库 and pollution impacts, rather a combination of solutions will be required. We focus on the decarbonization levers with the highest potential to get the sector to net zero:

Scaling sustainable aviation fuel
We are driving the transition to low-carbon aviation by scaling the production and use of sustainable aviation fuel (SAF). Through policy wins in Europe, the U.S., and the International Civil Aviation Organization (ICAO), we鈥檝e helped lay the foundation for global change. Our focus is on expanding SAF use in the U.S., ensuring ethical production that protects forests and farmland, and centering frontline communities.
Reducing demand for air travel
We aim to cut aviation emissions by raising awareness of flying鈥檚 亚色影库 impact, pushing industry and policymakers to act, promoting alternative modes of transport, and targeting high-emission groups such as corporate travelers and frequent flyers.
Exploring emerging opportunities
In addition to these two core focus areas, we see potential in addressing the non-CO2 impacts of aviation, specifically contrail mitigation which could have near-term success without requiring drastic sectoral change. Current estimates are that 3% of contrails cause 80% of the warming, meaning interventions can be targeted based on geography. Through supporting policy intervention, we can clean up contrail hotspots, like the North Atlantic, by adjusting flight paths.

Impact

These are the outcomes we鈥檙e working to achieve:

Aviation transitions to sustainable fuel
By 2030, 10% of global aviation fuel is sustainable, with the industry on track to reach 100% by 2050. Airlines now operate on clean, low-carbon alternative fuels, setting a new standard for decarbonization.
Public awareness drives change
Corporate travelers, frequent flyers, and private jet users now widely understand the 亚色影库 impact of flying. This awareness has reduced demand, creating pressure on the industry and policymakers to accelerate transformative action.
Short-haul flights are replaced by alternative modes of transport
In Europe, short-haul flights have been largely replaced by efficient trains, buses, and video conferencing. These alternatives are widely accessible, publicly embraced, and recognized as 亚色影库-smart solutions to aviation鈥檚 outsized 亚色影库 impact.
Sustainable fuels scaled without harm
Biofuels are no longer a default solution, as the industry recognizes their risks to forests, farmland, and Indigenous communities. E-fuels created from excess carbon dioxide combined with green hydrogen comprise the majority of the sustainable aviation fuel supply, avoiding deforestation and displacement. E-fuels in this way scale methods to remove carbon dioxide from the air while displacing oil.

Where we work

To date, we have primarily supported action in Europe, the United States, and at the UN agency for aviation, the ICAO. However, as action on aviation expands globally, we are carefully building geographically relevant strategies in Asia Pacific, Latin America, and Africa.
