Flying and Climate Change
Event summary by Olivia Oldham
Flying has become a staple of the modern world, though mostly for the global North. The carbon emissions of aviation are hotly debated, but it is generally agreed that it is responsible for around 3% of global emissions. So why do we care so much about flying? First of all, it is significantly--around 100 times, in fact--more carbon intensive than car travel. It also creates transport inequality--while exact statistics are hard to come by, it is unlikely that more than a couple of percent of the world’s population actually flies each year; and for those who do fly regularly, flying is their highest carbon activity.
Aviation is one of the highest emission sectors, and it is also one of the fastest growing. Now, however, due to the pandemic, the aviation sector is in crisis. How can we continue to fly while also mitigating climate change? How will Covid-19 affect our attitude towards flying into the future? We invited two experts, Michael Gill and Adam Klauber, to come speak with us to find some answers to these questions.
Michael Gill, the Director, Aviation Environment of the International Air Transport Association (IATA), spoke first. In his work at IATA, Michael leads work on sustainable regulation and policy advocacy with governments, the UN, and business partners. He is also the Executive Director of the Air Transport Action Group, leading their work to promote the aviation industry's sustainable growth. He has almost 20 years of experience in the aviation sector and he played a leadership role in the adoption of the international agreement on aviation and climate change (CORSIA) in 2016.
The long-term crisis of climate change means we need to take a long-term strategic approach to climate impact. In response to the acknowledgment in 2008 that the aviation industry was collectively responsible for a growing percentage of global emissions, airlines came together to decide a number of climate goals:
The overriding message Michael wanted to convey was that the aviation industry has recognised for over a decade that it has a significant impact on climate change and has a proactive and ambitious approach to addressing it by setting out targets that it will meet and having a very clear strategic plan involving collaboration across the sector--not just airlines but also manufacturers, airports and air traffic management. What is needed now is greater buy-in from governments through policy support, greater investment in alternative fuels, and a better understanding within the general and flying public of what the aviation industry is doing to address its impact.
Adam Klauber spoke next. He is the Principal, Sustainability and Energy at the Cadmus Group, an environmental consultancy firm. He also leads the sustainable aviation team for the Rocky Mountain institute (RMI), leading their global initiative to decarbonise aviation. He also writes for Forbes on aviation and the environment and was also the previous Head of Sustainable Aviation for ICF International. While at ICF Adam served as a representative to the UN's International Civil Aviation Organisation's Carbon Working Group
The Rocky Mountain Institute (RMI) is a global contributor to climate action. It was founded over 35 years ago and has focused on market-based solutions to climate change since its inception. One challenge it has focused on is how to unlock additional capital to support the sustainable aviation fuel price gap. Alternative fuels are very expensive, and airlines operate on low margins in a highly competitive environment, which makes it difficult for them to be able to spend funds on more expensive, more sustainable fuels. This creates a problem for investment, because investors are not usually willing to provide capital for a project unless they believe there will be market uptake.
To this end, RMI was involved in 2019 in the set-up of Clean Skies for Tomorrow (CST): a group of leaders in the aviation industry and the ‘demand sector’ (which includes large corporate buyers of passenger and air-freight travel). Work conducted by this group has determined that it may be possible for alternative fuels to replace all the liquid fuels used by the aviation industry.
CST is also working with climate NGOs so that the corporations involved can be recognised as global leaders who are adopting best practices. Offsets are currently seen as a method of last resort--it is much more desirable to achieve carbon reduction goals from within the sector itself. Sustainable fuels can achieve this, whereas offsets can’t. As such, CST is seeking to achieve recognition of sustainable fuels as a viable option to meet emission reduction tools.
Currently, the most competitive alternative fuel is twice the price of kerosene (traditional airline fuel), even after government subsidies have been applied. However, CST and RMI are working on a Sustainable Aviation Fuel Credit scheme to help reduce this difference, which Adam was confident will be successful. Importantly, work on this scheme is still moving forward despite the economic challenges brought to the aviation industry by the pandemic.
