E-book Moving Toward Net-Zero Carbon Society : Challenges and Opportunities
2021, the leaders of major industrial countries declared a shared goal of achieving a carbon-neutral international community by mid-century, during the G7 meeting. This objective is in alignment with the Paris Agreement, which aims to limit global warming to well below 2°C, and preferably to 1.5°C, compared to pre-industrial levels. In addition, major carbon-emitting countries such as the European Union, the USA, Japan, Korea, China, and India proposed specific timetables to achieve net-zero carbon emissions during the COP26 held in Glasgow in 2021. The objective of achieving net-zero carbon emissions involves reducing green house gas (GHG) emissions and balancing the remaining emissions through activities that remove GHGs from the atmosphere. These efforts reflect the urgency to address climate change and the need for coordinated action to achieve sustainable development goals. After then, an Expert Group was designated by the UN Secretary-General to address a “surplus of confusion and deficit of credibility” over net-zero targets of non-State entities among public and private sectors. In 2022, The COP27 held in Sharm el-Sheikh, Egypt, kicked off with the release of the report—“Integrity Matters: Net Zero Commitments by Businesses, Financial Institutions, Cities and Regions” (United Nations 2022) by the Expert Group with ten practical recommendations in four key areas of environmental integrity; credibility; accountability; and the role of governments. Policymakers should strengthen global partnerships more closely with scientists, experts, and enterprises to seek appropriate policy instruments. Measures could refer to the carbon tax, carbon pricing (Arimura and Matsumoto 2021), carbon sinks, global or regional carbon emission trade schemes, energy transitions, and other carbon–neutral policies toward a net-zero emission society by mid-century. In the post-COVID-19 era, adopting a more proactive climate change-responsive policy and establishing international cooperation to save the Earth is indispensable. At a time when carbon pricing policies are being formulated, climate change-related laws and policies will reshape global governance and the industrial layout between 2021 and 2030, and it is critical to move toward energy and industrial transformation, ecological conservation, and sustainable agricultural development. According to the Global Climate Action in the United Nations Framework Conven-tion on Climate Change (UNFCCC), as of November 2022, 30,765 actors are engaging in climate action globally (UNFCCC Global Climate Actions 2022), of which actors consist of 13,909 companies, 1,562 Investors, 3,451 organizations, 286 regions, 11,361 cities, and 196 countries. In the report, the experts convey the impor-tance of putting the net-zero pledge into practice by setting an evidence-based target. Moreover, utilizing voluntary credits could also help create transparent transition plans with accountability. Finally, these measures may improve the advocacy for accelerating the regulation roadmap. The book focuses on the emerging issues of net-zero from the perspectives of assessment, legal framework, regulation, and policy simulations among the cases grounded in Japan, South Korea, Myanmar, Bhutan, Bangladesh, Taiwan, and the Arctic. With aims to provide an evidence-based approach for policymaking, the content is divided into three sections: net-zero measures from the land through East Asia, Southeast Asia and South Asia (Chaps. 2–5); net-zero measures from the ocean through Taiwan and Japan (Chaps. 6–9), and net-zero measures under international framework (Chaps. 10 and 11).
