ABSTRACT
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.
ABSTRACT
Health risks and perceptions of residents living nearby landfills or stone mines/quarries have been well documented; however, the multiple impacts of these two pollution sources have yet to be investigated. This study aims at giving insights into the impacts of residents exposed to two pollution sources in Danang city, Vietnam: Khanh Son landfill and Phuoc Tuong quarry. In this cross-sectional study, 7-point-Likert scale questionnaires were used to collect information from 314 respondents which were divided into three groups: i) Landfill-Stone mine (LS) exposed group within 1 km from both sources, ii) Stone mine (ST) exposed group within 1 km from the stone mine, and iii) the far-exposed group about 2-3 km from the two emission sites. Air pollutants (including H2S, CH4, and total suspended particles (TSP)) and noise levels were also sampled. In addition, we estimated the potential health risk assessment due to the exposure to hydrogen sulphide in the study areas. The findings have shown that 1) There is a statistical difference (p-value < 0.001) between the two exposed groups and far-exposed group regarding health risks and residents' perceptions; 2) Compared to the ST exposed group, the LS exposed group statistically showed a higher perception to bad odours and skin diseases; lower satisfaction with regards to the personal health condition and the operation of the landfill; and higher willingness to change current living locations; and 3) There is evidence to indicate that elevated concentrations of air pollutants are associated with the high self-reported health risks and residents' perceptions. Urgent actions should be focused on the LS exposed group, landfill and quarry operations to prevent further adverse health effects.
