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.

The COVID-19 effect has been tendered on business aviation than commercial aviation. However, it is the operations that reported a surge in demand for business aviation. The demand has been witnessed from new businesses and and those who revamped their operations amid travel restrictions.
In 2020, the airline industry experienced a heavy loss of worth USD252 billion, reports IATA. The industry players were at risk, which included accounting with direct economic destruction. Prompted by other risks factors such as restrictions on movements, especially travel limitations due to COVID-19, there is a serious need for the industry to access its operations competently.
So here are two crucial questions that took the heat. First, how is the industry going to manage economic uncertainties, travel restrictions, and market instability? And second, how may these affect aviation business conclusions in the coming years?
Such considerations may include some crucial aspects. They are changes in valuation methods, revision of future investments with existing liabilities, re-assessment of forecasted fuel consumption, revision of manufacturing, marketing, and others.
This blog is aimed at capturing the impact of COVID-19. And how business aviation can proceed to bridge gaps across multiple travel restrictions, both during and after the COVID-19 crisis. To delve into detail, let's go further.
The Level of Airline Business Drop and Recovery
Globally, the aviation businesses were severely harmed by 80% in 2020. The industry players found it extremely complex to navigate the commitments. Also, their work with collaborations is slated for the same year.
Customers seemed uninterested in discussing new business acquisitions due to COVID travel restrictions on business. However, some operators preyed on lower prices and increased demand for aviation services and products. These were mainly in the manufacturing and marketing fields. The reason is some corporate clients easily adapted to the emergence of digital platforms. They switched to zoom calls to replace personal contacts and connections.
Michael Walsh, CEO of Aer Mobi, says,
“OEMs have now announced a major drop in production capacity. Potential buyers could be from booming sectors financial services and online sales as they may seek to purchase high-profit products. These will be only a few brilliant spots for new aircraft purchases for OEMs.”
On the same note, Shaun Quigley, Managing Director, Volantair Air Charter, says
“In the time of crisis, the ability is to “pull one’s head in." This is what will happen at least until the final quarter of 2021.”
Business aviation in 2021 will hover around 25% to 30% globally, says Jose Rego, Senior Director – Market Intelligence and Strategy, Embraer Executive Jets. The rebound will be sluggish until 2025.
While the travel businesses' situation in the pandemic is not up to mark, its believed that digital transformation is viable to conduct airline operations. Such transformation will drive sales eventually following the rise of trending technologies simultaneously.
Aviation Business by 2030
A major transformation is promised by an array of powerful new technologies and corporate clients’ pressure. The industry plays that turn this trend to their advantage have the opportunity to redefine, restructure, reform, and reshape their business amid air travel restrictions.
So how will the key players of the aviation sector take their businesses forward by 2025 and beyond? Here is the outline of vital forces that the sector will see transforming.
Robotics Maintenance
Currently, airline operations maintenance accounts for approximately 20% of the operating costs. However, as the pandemic happened, market players and novel inventions are placing big hopes on the intelligent automation of maintenance.
For example, Airbus uses two seven-axis robots on the new fourth A320 line in Hamburg to conduct 80% of their business operations, thus improving functional aspects for employees.
Intelligent automation is fueled by terabytes of data. The data could be stored and used by businesses to manage operations easily. The addition of robotics and AI in aviation has increased the digitalization shift landscape for established players. From automatic scanning, data mining to improved diagnostics, robotics has a significant role in the future of aviation operations and maintenance.
Use of Alternative Sources of Energy
The shifting of environmental sentiments has made the aviation industry include greenhouse gases, electrofuels, hydrogen, and even batteries. The industry has set a target of cutting down high energy emitter fuels by half by 2030.
Companies like Airbus have impressive plans to develop hydrogen planes in the next 15 years. Even for eleven years, SkyNRG has been known for supplying "advanced waste" biofuels to airlines. These fuels are recycled from industrial waste, cooking oil, agricultural and forestry residues.
New technologies from engineering and manufacturing of aerodynamic are going to play a significant role in upcoming airline trends like specialized and improved designs and the use of carbon-efficient biofuels and electric
In this case, the International Council on Clean Transportation (ICCT) research found out that around 5.5% of aviation fuel could come from sustainable origins by 2030. Basically, it would be primarily from advanced waste biofuels.
Aviation Business: Witnessing Some Hope
There is an anticipation that the established aviation businesses will pick up their pace by 2022 amid COVID 19 restrictions.
Interestingly, there has been a pick up in air travel (essential air travel) in a specific part of the world. However, in some Asian countries, travel activity is estimated to be less than 40%. But the travel demand is expected to be higher in the years ahead.
Aviation business operators expect expanded business with new criteria of sales—digital. They might witness growth due to new prospect acquisitions that have adopted the digital workforce. The businesses expect green shoots of growth in the travel industry. Especially from business travel classes as these are seeking to experience fly again.
Business aviation traffic in 2021 highlighted the growing interest from buyers. On this, Jose Rego, Senior Director – Market Intelligence and Strategy, Embraer Executive Jets elaborates,
“There may be a peripheral surge in demand from first-time buyers; I expect this to affect fractional sales initially.”
Therefore, now IATA estimates that governments globally will provide $160 billion in support, loans, and tax breaks so that airline businesses can cover current costs.
Safety is Priority, so is Business
The aviation industry acclaims that business aviation might be on track sooner. In this context, the presence of a qualified team and fast-track applications, software, and platforms could help operators to function in a safe and well-maintained way.
As the aviation industry continues to plan new air travel rules (essential), aviation business is at an optimum point. Its crucial role in supplies, sales, business development, and essential air travel services has redefined the face of business. Thus, in this way aviation business has paved the way to make a strong comeback in the coming years.

NASA is known for developing and launching spacecraft that have a significant environmental impact. However, the space agency is fully on board with the net-zero movement. NASA supports the White House's Aviation Climate Action Plan. It is helping fund several aviation projects that aim to reduce the aviation industry’s damage to the environment.
NASA’s Sustainable Flight Demonstrator Program
NASA focuses on technologies for single-aisle aircraft, which are the powerhouses of many airline fleets and account for nearly half of global aviation emissions. NASA's Sustainable Flight Demonstrator (SFD) project aims to reduce carbon emissions and keep the US competitive in the design of single-aisle commercial airliners, which are in high demand.
"Since its creation, NASA has worked with industry to develop and implement innovative aeronautics technology and has shared it with the world," said NASA Administrator Bill Nelson. "Now, with this ambitious new project, we're again joining with US industry to usher in a new era of cutting-edge improvements that will make the global aviation industry cleaner, quieter, and more sustainable."
NASA Wants to Reduce the Environmental Impact of Commercial Aircraft
The program’s goal is to build, test, and fly a large-scale demonstrator. NASA hopes to find a business partner for a Funded Space Act Agreement with its Armstrong Flight Research Center in Edwards, California, by the beginning of 2023.
The agreement would draw on private-industry knowledge and experience, with an awardee developing a suggested technical plan and committing considerable cash to the project. Under this agreement, NASA would not purchase an aircraft or any other hardware for its missions. The mission of NASA is to develop new and innovative technologies and capabilities.
NASA will collect data on the ground and in the air. Agency and industry teams can use it to test the airframe configuration and related technologies.
Moving Away From Space
NASA's technologies are typically cutting-edge. However, as with many high-end items, the benefits and applications frequently filter down to the masses. NASA's specialized technology and research frequently has civil aviation applications. It's interesting to see how NASA seems to be moving away from space and going after planes that fly closer to Earth.

Airplane travel is one of the most convenient means of transportation. Consequently, air travel is growing, and aircraft need to be more efficient. Furthermore, in the aftermath of the pandemic, the aviation industry appears to be committed to ensuring a sustainable airflight future. So, for this, aircraft need to be more efficient in production costs and fuel consumption.
An aircraft design depends on three of the most critical aspects. The first is the factor of reliability. Aviation is the only industry where it is impossible to overlook, rectify, or investigate a failed flight mechanism on the spot. The second factor is the need to minimize the weight and volume of its components to withstand load and fluctuating temperatures. And, the third factor is that it shows extreme concern from an environmental perspective. Temperatures on the ground can reach 60 °C and even -80 °C in the stratosphere, with supersonic aircraft reaching temperatures of over 200 °C.
As a result of these factors, the aircraft lubrication system and its requirements are critical. From an economic perspective, servicing and maintenance are a significant part of airlines' expenses after the purchase. In addition, the replacement of parts can cause airplanes to remain grounded for an extended period. Such circumstances can lead to a loss of time and money simultaneously.
From a safety aspect, failures at every level should be avoided. Failures like the shutdown of engines or breakage of engine parts can lead to aircraft failures or even crashes. So, by knowing all these issues around air travel, you can easily understand the interest in aircraft engine oil.
An Innovative Lubrication System for Aircraft Engine
Aircraft turbines revolve at up to 18,000 rpm (revolutions per minute). Due to this, internal temperatures can rise compared to the ambient temperature outside. So, aviation engines need an efficient oil-based lubricant to less pollute the environment and sustain long-distance air travel.
Recently, researchers in the EU-funded ELUBSYS project developed a novel way to use specified aircraft engine oil to promote efficiency and reliability. For this, SAF (Sustainable Aviation Fuel) is in high demand. Moreover, the project's innovative oil production will also help reduce an airline’s operating and maintenance costs. In this way, Europe’s aircraft manufacturers are way ahead in supporting future aircraft engine development.
“Aircraft engine turbines rotate at a very high speed with the help of the classic rubberized oil-seals used in the aircraft engine. The extremes of temperature and friction involved would destroy them. Yet aircraft engines need to stay lubricated.”
-Vincent Thomas of Techspace Aero in Belgium
Apart from this, the piston engine looks promising for the aviation piston engine industry. However, it seems like a piston engine holds an optimistic future in fuel economy. Now, with the inclusion of piston engines, there is more importance to using piston engine oil in the lubrication system for an aircraft engine.
So, how piston engine will be the game-changer for aircraft?
Piston Engine—A Game-Changer in Fuel Economy
Numerous aviation firms are developing a new type of internal combustion engine. Such engines promise a notable boost in fuel economy while also plummeting greenhouse gas emissions. In addition, start-ups like EcoMotors, Achates Power, and Pinnacle Engines are building variations on piston engines with the help of specific piston engine oil.
The engines serve as combustion chambers where fuel is ignited. That makes engines lighter in weight and faster in their operations with greater power density. In this way, piston engines result in less energy waste and thus operate more efficiently.
“The technology is worthwhile. However, it is a completely different concept compared to conventional engines,”
- Dean Tomazic, Vice President of FEV in Auburn.
There are more success stories from the aviation piston engine industry. These stories predict that, indeed, aviation is going through a significant transformation.
Another significant achievement comes from Pinnacle, based in San Carlos, Calif. It is developing a four-stroke, gasoline opposed-piston engine. The company’s founder, Monty Cleeves, invented a sleeve valve that ensures energy is used for propulsion instead of getting wasted after converting into heat.
Functions of the Lubrication System for Aircraft Engine Oils
What are the significant functions of lubricants in aviation oils and engines?
It is the function that realizes the importance of things. Isn’t it? So, to realize the importance of aircraft engine oils, it’s crucial to show the potential of the aircraft lubrication systems.
1 Friction and Wear Reduction
Lubricants reduce friction and wear in an aviation engine. The aircraft lubrication system deals with cooling, sealing, clearing, and fighting corrosion and rust in the engine.
Airplanes that are used seldom need the thorough protection from rust and corrosion that good aviation oils can provide. Also, frequently flying airplanes need lubricants for smooth engine operations and functions to avoid failures.
2 Acts as a Cooling Agent
But it is critical to use good aviation oils as lubricants. Oil is a heat-transform medium. Thus, a suitable oil should be used so that lubricants can keep the engine cool and smooth.
3 A life Saver of Aircraft Engines
Lubricants help in extending the life span of an aircraft engine. If an aircraft uses good aviation oil, for example, SAF, biofuels, and more, then there are fewer chances of any engine repairs. In this case, piston engines are the best fit for aircraft with high demand. Piston engines use highly lubricant piston engine oils, which increase the longevity of aviation engines.
Let’s look at some key takeaways from the market study of aircraft engine oil.
Aircraft Engine Oil: Key Takeaways from its Market Study
Commercial planes and business jets will likely witness high aircraft lubricant oil sales.
According to IATA, mineral oil demand is expected to rise by 25% by 2030.
Bio-based oils will dominate the aviation industry in response to soaring environmental concerns.
Maintenance, repair, and operations (MRO) activities will emerge as crucial parts of aviation to drive the global aviation lubricant market.
Lastly, what’s understood is that aircraft engine oil is the engine's lifeblood. Thus, the engine must function efficiently to encompass the length between overhauls.
Frequently Asked Questions
What does engine oil do in an aircraft?
Engine oil functions as a coolant. Up to 40% of an aircraft’s cooling comes from engine oil. Oil creates a seal between the piston rings, which reduces wear and friction andprovides better compression with increased fuel efficiency.
How is the engine oil lubricated?
Engine oil is lubricated with seals using air, which holds back the oil. Air and oil need to be separated. The air eventually vents out in the form of heat. That is why good oil is necessary for aircraft for lubrication.
What are the essential functions of engine oil?
The essential functions of engine oil are:
Minimizes friction and reduce wear
Cleans the engine
Transfers heat
Prevents corrosion
Forms a seal
Cools the engine parts
