Sustainability and Renewable Energy in the Aviation Industry
The aviation industry plays a significant role in contributing to global emissions, however, there are efforts underway to promote sustainability and the use of renewable energy to reduce the environmental impact of air travel.
Current State of Aviation Emissions
The aviation industry contributes approximately 2% of global carbon dioxide emissions. Additionally, the emissions released at high altitudes have a greater impact on the environment in comparison to ground-level emissions.
To address this, the aviation industry has set targets to reduce their carbon emissions. In 2009, the International Air Transport Association (IATA) set a goal to achieve carbon-neutral growth from 2020, and to cut net carbon emissions in half by 2050 compared to 2005.
Promoting Sustainable Aviation
One of the ways that the aviation industry is promoting sustainability is through developing more efficient aircraft. This includes investing in enhanced engine technology, aerodynamics, and lighter materials.
Additionally, many airlines are adopting sustainable practices such as installing winglets on planes which reduce fuel burn, implementing single-engine taxiing, and reducing unnecessary weight on planes through changes in catering and baggage handling procedures.
Some airports have also implemented initiatives to promote sustainable practices. For example, Atlanta's Hartsfield-Jackson International Airport has installed energy-efficient lighting and implemented a recycling program.
Renewable Energy in Aviation
The use of renewable energy in aviation is still in the early stages of development, however there are promising projects underway. In 2016, the Solar Impulse 2 completed a round-the-world trip powered entirely by solar energy. Additionally, various companies are exploring the use of biofuels to power planes.
Biofuels offer a promising alternative to traditional jet fuel, as they emit fewer greenhouse gases and can be created from renewable sources, such as waste vegetable oil or algae. Several airlines, including United Airlines and British Airways, have made test flights using biofuels.
Conclusion
The aviation industry has a significant impact on global emissions, but through sustainable practices and investment in renewable energy, progress is being made to reduce the environmental impact of air travel. It is important that governments, businesses and individuals continue to work together to promote sustainability and reduce carbon emissions from the aviation industry.
