Plastic waste pollution has been identified as a serious global issue, posing environmental risks in terms of massive waste generation, ocean pollution, and increases in greenhouse gas (GHG) emissions. Despite documented environmental impacts, it remains debatable whether the global plastic waste trade (GPWT) for reutilization and recycling, as part of the global circular economy (CE), has historically contributed to environmental benefits. To investigate if historical GPWT has contributed to environmental benefits in terms of reductions of GHG emissions, this study analyzed GPWT between China and trading countries through their trajectories, characteristics and driving forces of reductions of GHG emissions between 1992 and 2017. Results indicated an increasing trend of reductions of GHG emissions in GPWT between China and trading countries over 25 years. A net reduction of 8.27 million metric tons carbon dioxide equivalent (CO2e) was observed in 2012, nearly 84 times levels observed in 1992. Policy implications after China's recent ban of imports of GPWT in December 2017 and recent changes of GPWT to other Asian countries are discussed. Dramatic changes in sustainable approaches to GPWT for reutilization and recycling are required.

It is reported that the smog days in 2018 were much reduced compared to those in 2013 in China. The air environmental condition in China was much improved because of a number of comprehensive strategies adopted by the government such as phasing out backward production capacities and developing renewable energy industries. In addition, the Ministry of Ecology and Environment of the People’s Republic of China adopted a series of measurements to respond to the environmental events, including questioning the local highest official in serious air pollution areas. However, there are still lots of questions to be answered for a long term consideration. For instance, given the current situation of a gross domestic production (GDP) driven assessment system for officials’ credit, how long this high pressure pattern can respond to environmental events, such as air pollution, issue is a question. Therefore, unless this GDP driven assessment system is replaced by another assessment system it cannot last long. This paper also highlights the importance of developing low-carbon industries and circular economy as well as public involvement.

With the necessity of greenhouse gas (GHG) emissions reduction as a backdrop, the circular economy (CE) is increasingly being considered an effective response to this issue. Currently, China is facing a considerable challenge as it tries to respond to Paris Agreement targets; however, in many respects China is ahead of other nations as it relates to the implementation of such innovative strategies such as the circular economy policies. For over ten years, China has been investigating how the circular economy policies could be used to respond to GHG emission issue. In particular, the effects of such economic development pattern needs to be identified as well as the specific influence on GHG emissions reduction. This study presents an analysis of the Chinese plastic recycling industries (CPRI) through this lens. Plastics were specifically targeted, as such waste generation represents one of the highest fractions of global waste by mass, as well as the increasing public concerns of the environmental impacts of post-consumer plastics waste. Integrating the concepts of circular economy in this industry could be deemed an effective strategy, one which not only reduces post-consumer waste pollution, but also mitigates GHG emissions. This study analyzes the trajectories, features and driving forces of GHG emissions reduction achieved by the CPRI in the past ten years. The results show that the contribution of the CPRI to [specifically] CO2 emissions reduction increased from 7.67 million tons (MT) in 2007 to 14.57 MT in 2016; the scale factor and structure factor had significant impacts on GHG emissions reduction changes. A scenario analysis is presented based on projected impacts of various relevant national strategies. Finally, the policy implications of the CPRI's further GHG reduction measures are proposed.
