Environmental justice is the principle, concept, and practice that all human beings should have equal and equitable rights to enjoy safe physical environment. Due to increasing pollutions caused by industrialization, economic development and man-made other activities, however, environmental justice is denied to various poor segments of populations across the world. In order to address the growing inequalities and inequities for safe environment to these affected communities, environmental justice movement has emerged and accelerated during the past few decades. This article presents an analysis of the concept and practices of environmental justice within a global context. The article also highlights the roles and responsibilities of the public, business and NGO sectors in promoting environmental justice

Although in 2011 Japan finally decided not to participate in the second commitment period of the Kyoto Protocol to the United Nations Framework Convention on Climate Change, under the principles of sustainable development and common but differentiated responsibilities, it has probed the ways in which the ‘ultimate objective’ of the UNFCCC will be realized in the international community. With regard to socalled ‘emissions trading,’ since the middle of the 2000s, Japan has continuously adopted various methods and approaches for domestic emissions trading at local and central government levels. This article analyzes Japan’s recent efforts in introducing emissions trading schemes and finally refers to the Joint Crediting Mechanism, which covers the period until a future new agreement under the UNFCCC comes into effect.

This study had two main objectives. We first investigated which weather phenomena people were most concerned about in the context of climate change or global warming. Then, we conducted content analysis to find which words were more commonly used with climate change or global warming. For this, we collected web data from Twitter, Naver, and Daum from April to October 2019 in the Republic of Korea. The results suggested that people were more concerned about air quality, followed by typhoons and heat waves. Because this study only considered one warm period in the year of 2019, winter-related weather phenomena such as cold wave and snowfall were not well captured. From Twitter, we were able to find wider range of terminologies and thoughts/opinions than Naver and Daum. Also, more life-relevant weather events such as typhoons and heat waves in Twitter were commonly mentioned compared to Naver and Daum. On the other hand, the comments from Naver and Daum showed relatively narrower and limited terms and thoughts/ opinions. Especially, most of the comments were influenced by headlines of articles. We found many comments about air quality and energy/economic policy. We hope this paper could provide background information about how to promote the climate change education and public awareness and how to efficiently interact with general audiences.
