Issuer of report: HSBC Bank plc View HSBC Global Research at: https://www.research.hsbc.com  Transport accounts for 16% of GHGs – and airlines are one of the hardest modes to decarbonise, but pressure is growing  In this collaboration between our airlines, ESG and data science teams, we consider the response of EU and US airlines  We find a 2019 spike in climate discussions in earnings calls, with emissions disparities between low cost and legacy carriers Increasing focus on airlines to contribute to climate ambition: Policy-makers are increasing their focus on cutting transport sector emissions. As a part of this push, the CORSIA rules target 2020 as the intended peak year for aviation emissions. This regulatory push is being matched, in our opinion, by increasing public pressure and the greater focus we are seeing from investors on how climate change is being addressed by portfolio companies operating across the economy. Climate is suddenly a hot topic: We use Natural Language Processing tools to show that climate change has been discussed on airline earnings calls far more frequently during 2019 than in previous years (Chart 1 below). Clearly, the combination of regulatory and public pressure has made this a material subject for investors. However, these discussions have not been equally spread amongst airlines – European airlines have discussed climate change far more frequently than their US counterparts. A challenge for aviation that is greatest for low cost carriers (LCCs): We review a range of environment metrics. LCCs produce low CO2 per RPK, but notably high levels of CO2 per EUR. LCC environmental performance improves more slowly than legacy airlines and the absolute growth in LCC emissions is very high. The environment poses a challenge for the whole aviation industry, but we see the challenge to be greatest for low cost airlines.
