The aviation industry has allowed people to connect the world in unimaginable ways. Due to this, it has contributed massively to social and economic development globally.
However, the aviation sector produces nearly 1.8% of annual carbon emissions. It is almost half of the total growth in carbon dioxide emissions in the last twenty years due to the expansion of flights, increasing routes, and airline sizes.
In the loop, the commercial aviation sector has also been affected by climate change. The change is due to increased noise levels, air pollution, and waste production.
According to the International Energy Agency (IEA), the industry recorded 2.8% of global CO2 emissions in 2019. But now, the industry has pledged to be carbon neutral by 2050 through a focus on a critical low-carbon strategy, says IATA. By looking at this futuristic development, airline businesses are becoming more and more optimistic.
The Action Plan
The aviation industry has taken steps to reduce rising carbon emissions. The industry had framed targets that included carbon-neutral growth before the pandemic. But the pandemic compelled the industry to make some critical decisions. One of them is to fasten the action plan for low-carbon development.
McKinsey recently studied the industry’s emissions. According to the report, the industry's aviation emissions would be reduced by 18 to 35 percent by 2030. However, as the aviation industry’s growth is recorded from Asia, including India, China, and Southeast Asia, decarbonization can only work if airlines from these nations actively participate in the development.
“For aviation, zero-carbon is a bold, audacious commitment. But it is also necessary.”
-IATA Director General Willie Walsh
Airlines and other businesses are under pressure to make rapid progress towards lower emissions. It is because breakthrough technology like hydrogen-powered planes has started manufacturing.
For example, British Airways, Delta Air Lines, Inc., and United Airlines Holding Inc. have already made net-zero commitments by introducing hydrogen-powered planes. Similarly, JetBlue Airways Corp has set a target of 2040 to introduce low-carbon planes in no time.
So, by looking at above comitments, how will aviation progress in terms of low-carbon development? What are those fundamental ways that’ll guide the industry to see a sustainable future in real life?
4 Ways Aviation will Look Forward to Reducing Carbon Emissions
Green Fuel
Aviation considers green fuel as one of the quickest paths to low carbon development. Green fuel can be a game-changer in lessening carbon emission impacts. But, furthermore, it can lead to drastic climate change. Green fuel, also known as sustainable aviation fuel (SAF), is made from renewable sources such as plants or waste.
As per IATA, SAF can cut carbon emissions by nearly 80%.
But specific concerns like cost and availability are equally essential to think about. For example, the United States and other countries consider subsidies to decrease prices and increase supplies. They are practicing this due to limited availability. Also, some airlines are blending small amounts into the fuel they buy for their aircraft.
Other concerns, such as planes running properly on pure SAF, are also highlighted. In addition, flight engines based on petroleum fuel rely on their oily qualities to lubricate parts and function appropriately. So, it's unclear if green fuels offer that amount of strength in their engines to fly a flight.
Despite so many heated concerns (that are valid), the industry still looks good as Boeing (BA.N) studies the above issue. It has even committed to ensuring its planes are certified for 100% SAF by 2030.

Lower Carbon Technologies
Technological improvements to lower carbon emissions include retrofitting existing aircraft, adopting the latest fuel-efficient aircraft, retiring old aircraft, and others.
Several ongoing electric or hybrid-electric aircraft technology projects are in the pipeline. They are being identified to enter the industry between 2022-2030. In contrast, some of them are already in service.
Developments in Infrastructure
The International Civil Aviation Organisation (ICAO) has created plans to reduce fuel burn and greenhouse gas emissions (GHGs). The plans have been forwarded to optimize communication, navigation, surveillance (CNS), and air transport management (ATM) regarding zero-carbon development.
Apart from this, airlines are also working to align emission cuts with investments. Consumption of fuel usually covers 20-30% of operational costs. It is one of the highest costs of an airline business. So now airlines are considering adopting fuel-efficient flying and airport operations.
Collaborations
Today, aviation needs more stakeholders for a sustainable future. They can only increase the efficiencies and development of SAF.
Stakeholders from technology providers, oil companies, and energy production could drive demand and help bridge the cost gap. For instance, airlines commit to buying SAF at a particular price or at a different price than traditional fuel jets. These factors could eliminate market risks for fuel suppliers.
Next, airlines can work with B2B customers willing to pay for the decarbonization initiative. For example, airlines could use loyalty-program rewards as incentives for every customer to choose airlines that use SAF. Collaborations like these can help the industry accelerate its low carbon emission initiatives.
These Top Airlines Commit to Using New Technologies
Aviation industry leaders aim for 30% of the aircraft to operate with the help of new technologies by 2030. They strongly support the introduction of hydrogen and electric-powered planes to the market in order to reduce the industry's carbon footprint.
So, let’s see the airlines and their commitment to creating a sustainable aviation future.
Air New Zealand
Air New Zealand’s initiatives such as True Target Zero accelerate the adoption of zero-emission aircraft worldwide. Air New Zealand is delighted to work with other industry leaders working towards net-zero goals.
“Air New Zealand pledges to put low carbon solutions in place for all our smaller domestic and regional flights in the future. However, we know that the drive to decarbonize the aviation industry is impossible for one airline to tackle alone. Rather it’s a joint venture, and it's all about joining hands together.”
-David Morgan, Chief Operational Integrity & Safety Officer, Air New Zealand
Mokulele Airlines and Southern Airways
Mokulele Airlines, the largest intra-state carrier in America, has already worked for many years as a maven to bring electrification to its air transportation system.
“We are satisfied to join the World Economic Forum in seeking a global public commitment to promoting sustainable air travel.”
-Stan Little, Chairman & CEO, Mokulele Airlines and Southern Airways
Braathens Regional Airlines
The airline has the ambition to make its flights fossil-free by 2030. The airline has included electric planes, and with its partnership with True Zero Aviation, it is taking steps to accelerate towards actual low carbon emissions.
Can Aviation Make a Difference in the New Path of Development?
There are a lot of positive aviation stories from all over the globe. However, aviation also has some barriers to the new path of low-carbon development. Nevertheless, aviation can undoubtedly make a difference by introducing technologies, implementing result-driven strategies, implementing the right tools, and many more.
But from the customers' perspective, choosing to fly less can be another good reason to reduce an individual’s carbon pollution. The reduction can be up to 50% each year. So even avoiding long-distance flight travel could make a significant difference to aviation.
Business travelers could adopt or choose to use virtual meeting technology. These could be other crucial factors limiting the carbon footprint in the atmosphere.
Whatever you choose to opt for, it is high time to contribute to a more sustainable aviation sector for the future.

Can the aviation industry have a net zero-carbon emissions? Can technology assist in achieving net-zero emissions?
Presently, customers are taking more flights than ever as the industry is set to grow post-pandemic effects. Data from IATA shows that the UK aviation industry alone ejected thirty-seven million tonnes of CO2 into the atmosphere in 2020. That’s an average of 9% more in tonnes of emission the industry recorded in 2018.
The warnings are transparent. In the latest reports of Intergovernmental Panel on Climate Change (IPCC), the effects of global warming are escalating.
“We know the challenges of climate change the world is facing. It has only continued to intensify,”
-Nicholas Calio, president and CEO of Airlines for America
Airlines are subsequently embracing their actions towards the recovery of their business. There is a need to take even braver, more momentous steps to address this challenge.
Airlines have been focused on carbon offset programs for years. It has previously invested in projects and organizations that assist in reducing the impact of CO2 emissions.
In March 2021, the U.S. airline industry announced that its market leaders are committed to achieving zero carbon emissions by 2050.
The aviation industry is currently rising at between 4% and 5% a year. And the number of passengers will double every 15-20 years. How will the industry let fly with zero emissions? Certain plans strongly focus on the increasing use of sustainable aviation fuel and jet fuel. These fuels are produced from sources such as plant oils, municipal waste, agricultural residue, fossil fuels, and other interim steps.
The blog accumulates some of the best ways that aviation has unveiled on the grounds of zero carbon emissions.
Escalating the Use of Alternative Fuel
The escalating use of alternative fuels is perhaps the most significant proposed carbon reduction initiative for sustainable aviation fuel (SAF) usage. Sustainable fuel is going to be created from plant or animal material. One of the examples is waste oil.
It is studied that SAF has the potential to cut life-cycle emissions from aviation by 80%. It can be blended with conventional jet fuel without making major changes in aircraft designs. But, as technology is concerned with SAF usage, it can be eight times more expensive than conventional jet fuel. SAF currently values less than 0.1% of the almost 300 million tonnes of fuel that commercial airlines use every day.
some companies are taking regulatory incentives in joint efforts with aviation after looking at the costs and ensuring that more SAF is used in the future. Let’s see which corporate companies are setting commendable aviation-related commitments.
Microsoft partnered with Alaska Airlines. Together, they are working to cover CO2 emissions to make their employees’ travel safe by introducing SAF credits.
FedEx has committed to purchase 13 million liters of sustainable aviation fuel from Red Rock Biofuel. It is a part of their long-term net-zero emission strategy.
Express GBT created an alliance to help in increasing supply SAF to under carbon reduction initiative and become zero carbon-emitting by 2050.
Industry-Wide Efforts
The path to climate recovery with zero airline emissions will require a collective effort from all industries. This also includes governments. They must take responsibility for the impact of certain activities, products, and policies have on the environment. The production of fossil fuels is one of them. So, the aviation industry must reduce its dependency on fossil fuels for air travel.
Industries such as energy, road transport, infrastructure, manufacturing, and finance are being collectively responsible for creating a risk-free airline emission. For example, policies of energy transition must include a change in the production plan. Road transport efforts should be advanced by designing electric vehicles. Manufacturers should bring in new technology to support the creation of lightweight engines and aircraft parts. All of them should join hands for a sustainable future for aviation.
The Role of Government Investments
Government bodies play a crucial role in heading up carbon reduction initiatives. The initiative will have solutions such as new aircraft technology and more efficient infrastructure and operations. It also includes the development of zero-carbon energy sources like hydrogen and electric power generation.
According to IATA, 1.8 gigatons of carbon will be required to sustain the aviation industry in 2050. The prediction can achieve 65% of carbon for sustainable aviation fuels.
What are other solutions in demand to commit to addressing a zero-emission environment? It includes:
Fuel-producing companies are to bring large-scale, cost-competitive sustainable aviation fuels (SAF) to the market.
Governments and air navigation service providers (ANSPs) eliminate inadequacies in air traffic management and airspace infrastructure.
Aircraft and engine manufacturers produce more efficient aircraft engines and propulsion technologies.
Airport operators provide the required infrastructure to supply cost-effective SAF.
Airline Firms Decarbonizing Aviation
Presently, aviation is driving towards a new chapter of growth. And the pillars of growth are the firms that are continuously making efforts to make aviation a risk-free industry.
Let’s see how aviation firms are contributing to making a zero-carbon emission sky for safe air travel for the future.
Delta Airlines
Delta and Aviation Climate Taskforce are initiating technological innovation and accelerating the research and development of emerging technologies. Emerging technologies refer to reducing CO2 footprint production. They are focusing on their approach towards medium-term solutions, near-term solutions and long terms solutions.
The mid-term solutions include synthetic fuel. The near-term solutions focus on emerging bio-based Sustainable Aviation Fuel (SAF) pathways. And long-term solutions include hydrogen technologies. ACT will aim to support the advancement of these technologies through two crucial pillars:
An Innovation Network
A Collaboration Forum
JetBlue
JetBlue went carbon neutral for all its flights. It went through carbon offset programs in partnership with the CarbonFund.org Foundation. The investment included solar, wind, and hydrogen-energy project initiatives.
Apart from this, JetBlue also invested in hundreds of global carbon offset programs to support renewable energy efforts.
“views carbon initiative as a platform for other industry-wide environmental improvements that support lower emissions.”
-JetBlue
The best part is that JetBlue also invested in sustainable aviation fuel on flights. They are currently operating from San Francisco International Airport.
American Airlines
American Airlines changed its strategy of using traditional jet fuel. The airline has committed to purchase 9 million gallons of SAF to lower CO2 emissions in the next three years.
Southwest Airlines
On Earth Day 2021, Southwest Airlines announced it would continue to support the U.S. Department of Energy’s National Renewable Energy Laboratory (NREL). NREL works to develop cost-effective low-carbon aviation fuels that are generated from waste.
The airline SAF will play a vital role in getting the atmosphere carbon neutral and will be able to achieve carbon neutrality by 2050. On this, NREL estimates that wet waste typically produces enough energy to provide about 20% of jet fuel consumption.
How Will the Industry Embrace Greener Air Travel Once It Returns to the Sky?

A New System That Aims to Create Carbon-Neutral Aviation
Scientists have achieved an amazing breakthrough in the development of carbon-neutral fuel for the aviation industry. An aviation fuel production system that uses water, sunlight, and carbon dioxide has been put into action. Its design was published on July 20th, 2022, in the journal Joule. The dream of achieving carbon-free aviation could become a reality with this development.
“We are the first to demonstrate the entire thermochemical process chain from water and CO2 to kerosene in a fully-integrated solar tower system.” - Aldo Steinfeld, Professor, Study Corresponding Author, ETH Zurich
The aviation industry accounts for approximately 5% of the global anthropogenic emissions that contribute to global climate change. The industry heavily relies on kerosene, commonly known as jet fuel, a liquid hydrocarbon fuel derived from crude oil. There are no clean options to power commercial flights on a global scale at the moment.
Production of Synthetic Kerosene
This breakthrough, with the help of solar energy, makes it possible to produce synthetic kerosene from water and carbon dioxide instead of crude oil. The amount of CO2 emitted during kerosene combustion in a jet engine equals what is consumed during its production in the solar plant. It is what makes the fuel carbon neutral, especially if the CO2 in the air is captured and directly used as an ingredient, which could be possible in the near future.
As part of the European Union's SUN-to-LIQUID project, Steinfeld and his colleagues put forward a system that uses solar power to generate drop-in fuels—synthetic alternatives to fossil-derived fuels like kerosene and diesel. Solar-produced kerosene is consistent with the current aviation infrastructure for allocation, fuel storage, and use in jet engines. It can also combine with fossil-derived kerosene, according to Steinfeld.
High Hopes for the Future
Steinfeld and his team began scaling the construction of a solar fuel manufacturing plant at the IMDEA Energy Institute in Spain half a decade ago. The plant has 169 sun-tracking reflective panels that redirect and concentrate solar radiation into a tower-mounted solar reactor. This concentrated solar energy then powers redox reaction cycles in the reactor’s porous ceria structure, which is not absorbed but can be reused. It transforms the water and carbon dioxide into syngas, a customized mixture of hydrogen and carbon monoxide. This syngas is then injected into a gas-to-liquid converter and is finally converted into liquid hydrocarbon fuels such as kerosene and diesel. Steinfeld and his team are working on amping up the reactor’s efficiency from the current 4% to more than 15%.

Each year airlines begin new sustainability initiatives, experiment with biofuels, and offset their carbon emissions on selected flights; yet, sustainability should not only be a topic of discussion when an aircraft is in the air but also when it’s on the ground.
In just one year, a Boeing 777, 787, Airbus A330, and A350, burn an extra 265,000 litres of fuel due to the 1% increase in drag. As a result, a full year’s operations of such an aircraft costs US$77,600 more than during the previous year. A dirty aircraft exterior is full of microscopic patches of dust and mud that impact the airliner’s operational efficiency by creating turbulent airflow across the whole fuselage. While the problem of additional drag is not new, there are no solutions to combat it other than performing regular cleaning of the aircraft’s exterior.
Reducing drag – through cleaning – on aircraft fuselage, wings, engine cowlings, and stabilizer brings another challenge; how to remain sustainable while performing the exterior cleaning process? A popular, yet wasteful pressurized water cleaning technique requires more than 11,300 litres of water to clean one Airbus A380 aircraft and more than 9,500 litres to clean a Boeing 777. Traditionally, aircraft are cleaned four to five times per year, and with more than 48 thousand airframes in the world, the amount of water used each year is immense. As a result, the positives of clean fuselages are outweighed by the negatives of wasteful usage of expensive and environmentally important resources.
This raises a question: whether it is possible to be eco-friendly in the aviation industry when one solution brings even more challenges than benefits? While the answer may look complicated, the definite answer is yes. The use of robots in household applications has proven that robotification is an inevitable and much-needed process to achieve even more efficient operational performance.
One of the solutions to address the inefficient and time-consuming process of washing an aircraft fuselage is to employ an aircraft exterior cleaning robot. The market offerings like Nordic Dino, have been perfected and adapted to work with a wide range of aircraft fuselage types. Such robots are designed to minimize the use of water and detergent on every wash; saving more than 30% more water when compared to traditional washing methods. At the same time, built with sustainability in mind, the robots can be equipped with electric motors, further minimizing the environmental impact.
“Sustainability and eco-friendliness should not be viewed as challenges or impossible achievements in the aviation industry. By utilizing the right equipment, finding alternatives to polluting methods, and increasing efficiency at every step possible, companies could come one step closer to operational efficiency as well as sustainability targets. Our offering, Nordic Dino can reduce the use of water and detergent and can be powered by electricity, reducing carbon and nitrogen dioxide emissions. By the robotification of the cleaning process we present a solution to MROs and dedicated aircraft cleaning companies to become green.” – commented Jan Brunstedt, CEO of Aviator Robotics AB.
