Divergences between the European Union and China on reducing international aviation emissions.

This paper provides a historical overview regarding the emergence, development and deepening of divergences between the European Union (EU) and the People's Republic of China (China) in reducing global aviation emissions. It focuses on their divergences on three specific issues, i.e. under which framework to tackle global aviation emissions, whether and how to reflect the Common but Differentiated Responsibilities and Respective Capabilities (CBDR-RC) principle in the design and implementation of the global market-based measures (MBMs) for international aviation and which role the International Civil Aviation Organization (ICAO) should play in offsetting these emissions. Besides, this paper explains the driving forces behind these divergences by examining both normative and economic-related factors, which have formed different stances of both sides. From a Chinese perspective, considerations about the issues of state sovereignty, fairness regarding burden sharing in tackling climate change, the development of China's aviation and aircraft manufacturing and its limited capability in promoting the large-scale SAF deployment help explain its hardline stance on reducing global aviation emissions. As for the EU, perceptions of its leading role in the global climate governance and the CBDR-RC principle, the targets of strengthening the EU ETS role in the global carbon market, and the competitiveness of the European airlines are underlying reasons behind its attempt to include the international aviation under its ETS. Moreover, the EU member states' support to the ICAO can be explained through the conformity between the emissions offsetting objectives under this organisation and the EU's current climate policies.
