How does COVID-19 affect the implementation of CORSIA?

Area of Science:

• Environmental Science
• Economics
• Transportation Studies

Background:

• The Carbon Offsetting and Reduction Scheme for International Aviation (CORSIA) aims to stabilize international aviation emissions.
• The COVID-19 pandemic significantly disrupted global aviation activity, necessitating an evaluation of CORSIA's implementation.
• Understanding aviation's growth trajectories and the impact of policy adjustments is crucial for environmental and economic sustainability.

Purpose of the Study:

• To investigate the effects of the COVID-19 pandemic on the implementation of CORSIA.
• To analyze the differential impacts of aviation activity changes on developed and developing countries.
• To assess the financial implications of CORSIA, including the effects of baseline revisions.

Main Methods:

• Utilized Automatic Dependent Surveillance-Broadcast (ADS-B) data for international aviation activity.
• Employed Gompertz and Logistic curve forecasting models.
• Incorporated four distinct COVID-19 pandemic scenarios for analysis.

Main Results:

• International aviation in developing nations shows rapid growth, contrasting with slower or saturated trends in developed countries.
• Findings retrospectively support the ICAO Council's revision of the CORSIA implementation baseline, yielding cost savings for nations like China, the USA, UAE, and UK.
• Despite baseline adjustments mitigating economic pressure, CORSIA imposes a substantial financial burden on international aviation enterprises.

Conclusions:

• The COVID-19 pandemic has altered aviation's growth patterns, impacting CORSIA's effectiveness.
• Baseline revisions for CORSIA provided significant financial relief, highlighting the importance of adaptive policy.
• CORSIA implementation continues to present economic challenges for the aviation industry, requiring ongoing assessment and potential mitigation strategies.
