How to Allocate the Allowance for the Aviation Industry in China’s Emissions Trading System

Abstract

In order to combat climate change and control emissions in the aviation industry, it is necessary to research the aviation industry’s potential application of China’s Emissions Trading System (ETS), especially the carbon allowance allocation (CAA). On the basis of historical and benchmarking CAA schemes, considering the responsibility, capacity, and potential of firms, this study proposes the indicators CAA (ICAA) scheme. Moreover, considering firms’ costs, this study also proposes a multi-objective CAA (MCAA) scheme. Finally, the most effective scheme is reported. Results show that under ICAA and MCAA, caps are lower and basically consistent with the emissions reduction target of the “13th Five-Year Plan Work Program for Controlling GHG Emissions of Civil Aviation in China” and international goals. Different types of airlines gain different quotas according to their income and the number and age of their aircraft. The cost of reducing emissions in each scheme is less than 0.35% of their total costs. Under the ICAA-S, ICAA-P, and MCAA schemes, airlines can achieve a reduction in emissions of 19.7%, 20.9%, and 19.6%, respectively. Moreover, under MCAA, the difference in quotas between airlines is smaller. Therefore, of the schemes evaluated, MCAA is the most effective.

“…Sustainability Accounting Standards Board (SASB) where This board is an independent organization that establishes sustainability accounting standards that satisfy the demands of investors by raising the quality of sustainability disclosing information (Bishop, 2018). The Institute of Chartered Accountants of Australia (ICAA) encourages the adoption of the GHG Protocol requirements, with a particular emphasis on carbon disclosure through clean development mechanisms and carbon emissions disclosure (Tang & Hu, 2019).…”

Climate Change Mitigation Pathways for the Aviation Sector

“…The CORSIA and the EU ETS operating in parallel would ensure that international flights, as well as flights within the EU, are subject to CO 2 reduction schemes [18]. Under the carbon allowance allocation scheme, airlines can achieve a reduction in emissions of about 20% [83]. ICAO estimates an offset target of about 2.5 billion tonnes of CO 2 between 2021 and 2035 [84].…”

“…The key criteria that any aircraft operator must fulfill under a single global MBM are to maximize environmental integrity, minimize competitive distortions, and reduce administrative complexity [41]. Proper emissions allocation schemes that consider various indicators of airlines, such as the income and the number and age of aircrafts, are also fundamentally important for yielding dividends from the reduction efficiency of airlines emissions [83]. Setting benchmark emission intensities while offering airlines options to sell and/or purchase permits is also proven to incentivize airlines to reduce emissions [142].…”
