Innovation in sustainability and social impact in the aviation industry

September 27, 2023

The aviation industry accounts for only 3% of global greenhouse gas emissions, but is proving to be one of the most difficult sectors to decarbonize. Moreover, it remains an industry that with a heavy operational footprint, including flight and maintenance operations, manufacturing processes and supply chain management.

In order to reduce its impact on the environment, the aviation industry has been exploring various solutions such as alternative fuels, improved engine and aircraft design, carbon offsetting programs, and more efficient operational practices. In this briefing, we look at current sustainability initiatives in the aviation industry as well as ones that can be developed in the future.

One solution that has gained traction in recent years is the use of sustainable aviation fuels (SAFs). These fuels are made from renewable sources such as waste oils, agricultural residues, and non-edible plants. SAFs are currently blended with traditional jet fuel and can reduce emissions by up to 80% compared to conventional jet fuel. However, the production and distribution of SAFs is expensive and currently only makes up a small percentage of total aviation fuel consumption.

Another approach to reducing emissions in the aviation industry is through improved engine and aircraft design. This includes using more efficient engines, lightweight materials, and aerodynamic designs to decrease fuel consumption. Additionally, implementing sustainable practices such as recycling and reducing waste in the manufacturing process can also help to reduce the overall environmental impact of aircraft production, as well adapting equipment to better accomodate families, disabled and the elderly.

Carbon offsetting programs have also become popular in the aviation industry as a means of reducing emissions. This involves investing in projects that aim to reduce carbon dioxide in other areas, such as renewable energy or reforestation projects. While this is not a direct solution to reducing emissions from flights, it can help to mitigate the industry's impact on the environment and meet regulatory requirements.

Furthermore, changes in operational practices can also have a significant impact on reducing emissions. This includes measures such as optimizing flight routes and implementing more efficient air traffic control systems to reduce fuel consumption, using alternative forms of transportation for ground operations at airports and implementing more direct flight paths to decrease fuel consumption. This also includes conducting regular maintenance on aircraft to ensure they are operating at maximum efficiency and minimizing their environmental impact, including through paperless cabins.

In addition, the development of electric or hybrid aircraft can potentially greatly reduce emissions and noise pollution in the future. However, there are still challenges in terms of battery technology and infrastructure that need to be addressed before electric/hybrid aircraft can become a viable option for commercial flights. Nonetheless, research and development in this area is ongoing and holds promise for a more sustainable aviation industry.

Achieving these results is not only a question of operational excellence, but improving engagement with stakeholders. This includes goverments, who must adopt regulations and incentives to encourage airlines and manufacturers to adopt more sustainable practices, and employees, who must be trained and encouraged to embrace a culture of sustainability within the industry. From a corporate social responsibility perspective, actors in the aviation industry must also seek to improve the the impact of air travel on local communities and the environment, especially in areas surrounding airports, and minimize any negative effects.

Another consideration for the aviation industry is green financing and investment. This involves directing capital towards sustainable initiatives, such as SAF production or research and development of electric/hybrid aircraft. It also includes incorporating sustainability into decision-making processes and considering the long-term environmental impact of investments. This can help to accelerate the transition towards a more sustainable aviation industry.

It is clear that the aviation industry is making progress towards reducing its environmental impact, but there is still much work to be done. By implementing a combination of sustainability initiatives and engaging with stakeholders, solutions can be implemented to reduce environmental impact. Through a combination of alternative fuels, improved design, carbon offsetting programs, and more efficient operational practices, the industry can work towards a more sustainable future for air travel.
