Freight air transport is an essential part of global trade, enabling the movement of goods across continents and supporting economic growth. However, it is also a significant contributor to greenhouse gas emissions, with carbon dioxide (CO2) being the primary pollutant. As the world faces the challenges of climate change, reducing carbon emissions in the freight air transport sector has become a critical priority. Decarbonisation, or the process of reducing carbon emissions to zero, is crucial for meeting climate targets and ensuring a sustainable future.

What is Decarbonisation in Freight Air Transport Sector and Why is it Important?

Decarbonisation in the freight air transport sector refers to the reduction of carbon emissions associated with the movement of goods by air. It is essential to mitigate the impact of climate change, which is caused by the accumulation of greenhouse gases in the atmosphere. The freight air transport sector contributes significantly to carbon emissions, accounting for about 2.5% of global CO2 emissions. As the demand for air freight continues to grow, the sector's carbon footprint is expected to increase, making decarbonisation crucial to achieving climate targets.

The Paris Agreement, signed in 2015, aims to limit global warming to well below 2 degrees Celsius above pre-industrial levels and pursue efforts to limit the temperature increase to 1.5 degrees Celsius. To achieve this goal, the International Civil Aviation Organization (ICAO) has set a target of reducing carbon emissions from the aviation sector by 50% by 2050 compared to 2005 levels. Decarbonisation of the freight air transport sector is, therefore, critical to meeting this target and ensuring a sustainable future.

What are the Main Sources of Carbon Emissions in Freight Air Transport Sector?

The freight air transport sector's carbon emissions come from various sources, including aircraft operations, ground operations, and supply chain activities. The primary source of carbon emissions is aircraft operations, which account for about 98% of the sector's emissions. The burning of aviation fuel in aircraft engines releases CO2 into the atmosphere, contributing to global warming. Other greenhouse gases, such as nitrogen oxides (NOx) and water vapor, also contribute to the sector's environmental impact.

Ground operations, including airport operations, ground handling, and cargo handling, also contribute to carbon emissions in the freight air transport sector. These emissions come from the use of vehicles, equipment, and energy consumption in buildings. Supply chain activities, such as packaging, transportation to and from the airport, and warehousing, also contribute to carbon emissions in the sector.

How Can We Reduce Carbon Emissions in Freight Air Transport Sector?

Reducing carbon emissions in the freight air transport sector requires a combination of measures that address aircraft operations, ground operations, and supply chain activities. The following are some of the ways to reduce carbon emissions in the sector:

1. Aircraft Technology: The development of more fuel-efficient aircraft and the use of alternative fuels can significantly reduce carbon emissions from aircraft operations. The use of electric and hybrid-electric aircraft is also a promising technology that can help decarbonize the sector.
2. Operational Efficiency: Improving operational efficiency, such as reducing aircraft weight, optimizing flight paths, and reducing taxiing time, can reduce fuel consumption and carbon emissions.
3. Ground Operations: The use of electric and hybrid-electric ground vehicles and equipment, as well as the use of renewable energy sources in buildings, can reduce carbon emissions from ground operations.
4. Supply Chain Efficiency: Improving supply chain efficiency, such as reducing packaging waste, optimizing transportation routes, and using low-emission vehicles, can reduce carbon emissions from supply chain activities.
5. Carbon Offsetting: Carbon offsetting involves investing in projects that reduce carbon emissions in other sectors to compensate for the emissions generated by the freight air transport sector.

What are the Challenges Facing Decarbonisation in Freight Air Transport Sector?

Decarbonisation in the freight air transport sector faces several challenges, including technological, economic, and regulatory barriers. The following are some of the challenges facing decarbonisation in the sector:

1. Technological Barriers: Developing more fuel-efficient aircraft and alternative fuels is a complex and expensive process that requires significant investment in research and development.
2. Economic Barriers: The cost of developing and implementing decarbonisation measures can be high, and the freight air transport sector operates in a highly competitive market, making it challenging to pass on the cost to customers.
3. Regulatory Barriers: The lack of a global regulatory framework for carbon emissions in the aviation sector makes it challenging to implement and enforce decarbonisation measures.
4. Infrastructure Barriers: The lack of infrastructure, such as charging stations for electric ground vehicles and alternative fueling stations for aircraft, can hinder the adoption of decarbonisation measures.

What are the Implications of Decarbonisation for Freight Air Transport Sector?

Decarbonisation of the freight air transport sector has significant implications for the sector, including economic, environmental, and social impacts. The following are some of the implications of decarbonisation for the sector:

1. Economic Impacts: Decarbonisation measures can increase the cost of air freight, making it less competitive compared to other modes of transport. However, it can also create new business opportunities, such as the development of alternative fuels and aircraft technology.
2. Environmental Impacts: Decarbonisation measures can significantly reduce the sector's carbon footprint, contributing to global efforts to mitigate climate change. It can also improve air quality and reduce noise pollution in communities near airports.
3. Social Impacts: Decarbonisation measures can create new job opportunities, such as the development and maintenance of alternative fueling infrastructure and electric ground vehicles. It can also improve the sector's reputation and increase public trust in the industry.
