To Realise “Net Zero” in Asia~Methodologies of Support for Implementing Climate Change Mitigation Plans~

Summary

To achieve net-zero (a climate-neutral society), it is necessary to analyse the impact of climate change mitigation measures on socioeconomic activities and ecosystems, and then consider and implement sustainable measures. This session featured presentations by four researchers and a panel discussion to consider methodologies for supporting the implementation of mitigation measures, taking into account the local characteristics of Japan and other countries in Asia.

The first speaker discussed the trade-offs (both positive and negative effects) of transitioning to a decarbonised society, using examples of global impact projections. They emphasised the importance of considering various ripple effects when promoting decarbonization policies. The second speaker highlighted the importance of Asia's role in achieving the Paris Agreement's 1.5/2°C targets. They presented quantitative reduction scenarios for multiple mitigation measures in various Southeast Asian countries up to 2050. The third speaker stated that the follow-up and review (FUR) framework for SDGs can also be utilised to evaluate goals and measures for achieving net-zero. The final presenter introduced a model of a region in Japan, suggesting that presenting future scenarios using real data from smart monitoring systems is effective in achieving regional decarbonisation.

Key Messages
  • Current GHG reduction targets are insufficient to achieve the 1.5℃-2℃ Paris Agreement goal. With Asia contributing nearly half of global emissions in 2023, the region’s mitigation measures are critical.
  • Decarbonisation can lead to negative social impacts. Quantitative evaluation of these effects is essential to design and implement mitigation and adaptation measures strategically, ensuring sustainability
  • Local decarbonisation efforts, such as Shin-chi Town’s Smart Monitoring System, demonstrate the value of using local data for scenario planning and community acceptance. Such approaches can guide decarbonisation across Japan and beyond

Global analyses of climate mitigation for achieving net-zero emissions and sustainable development

We implemented a ERTDF project Global analyses of climate mitigation for achieving net-zero emissions and sustainable development and worked on presenting the emission pathways necessary to achieve climate targets, evaluating the climate impacts that would occur under those emission pathways, and examining strategies for climate mitigation measures that takesustainability into account. In the session, I will introduce research results from this project,such as climate impact projections that focus on intergenerational and interregional equity, and evaluations of implication of climate mitigation policies on various sustainability aspects.

Results and Roles of Research on Decarbonization Scenario Development in Asia

The National Institute for Environmental Studies (NIES) has collaborated with researchers in Asia to apply the Asia-Pacific Integrated Model (AIM) to Asian countries and develop their dec arbonized society scenarios through the Environmental Research and Technology Development Fund S-6, 2-1908, 1-2202 and others. This presentation will introduce the results of decarbonized society scenario research in Asia. The, the roles of scenarios as research outputs and the importance of capacity development will be explained through the process of model development, scenario quantification, and communication with stakeholders as social implementation of the obtained research results in Asia.

Implications from the Study on the Governance of Follow-up and Review for the achievement of the SDGs

There are growing interests in tackling climate goals and the Sustainable Development Goals (SDGs) synergistically. It is increasingly important not only to implement but also to follow-up and review such synergistic policies for climate and the SDGs. Since 2022, the IGES research team has been studying how follow-up and review governance can be strengthened to spur further implementation to achieve the SDGs. This presentation will share the research results and discuss their implications for follow-up and review mechanisms for climate and related-synergy policies.

Regional Innovation Research Approach toward Carbon Neutral Regions and Projects

Integrative research approach contemplating carbon mitigation actions based on the local characteristic is discussed to identify future roadmaps and green innovation demonstration projects as well as evaluation system of existing local features and future eco-environmental effects. Based on the diagnosis of regional advantages and disadvantages, regional integrative simulation system to design optimal future targets with urban and regional scale to identify effective roadmaps has been developed. Planning and decision support system for demonstration projects to bridge present local situations and future decarbonization targets with optimal combination of technologies and social systems will be discussed. The results would be applied into implementing for eco-city panning under the interactive collaboration among public-private stakeholders. Smart monitoring systems are developed and implemented to support multi-stakeholder discussion for co-design procedures through quantification and visualization.
