This presentation introduces the "Climate pOlicy assessment and Mitigation Modeling to Integrate national and global Transition pathways" (COMMIT) project. The project aims to: 1) improved modelling of national low-carbon emission pathway; and 2) improved analysis of country contributions to the global ambition of the Paris Agreement. This project...

This study presents a multi-model analysis of long-term climate policy of Japan, whose mid-century strategy is subject to an ongoing policy debate, focusing on the carbon dioxide emissions in the energy sector. The models demonstrate multiple future pathways of the low-carbon energy system in Japan. The median of marginal abatement cost is found to...

The presentation provides summaries of messages relevant to forest in IPCC Special Report “Global Warming of 1.5 °C” and recent progress on REDD+.

We assess the feasibility of Japan’s NDC along with 80% emission reduction by 2050, comparing the role of uncertain nuclear power deployment to other key uncertainties by means of a computable general equilibrium (CGE) model.

This poster presentation received The People's Choice Award at the 13th Biennial International Conference on Ecobalance, 9-12 Oct. 2018, Tokyo, Japan. The poster was selected among over 90 posters by the votes of the participants. The Paris Agreement envisions a net negative carbon society by the second half of the century. Existing studies on...

This presentation explains trends of national greenhouse gas (GHG) inventories in submitted biennial update reports (BURs) by developing countries under the UNFCCC. It illustrates country's progress in reporting GHG inventories in terms of methodologies used, gases and GWP used, and years reported with emissions data, etc. In some cases, countries...

Achieving long term climate mitigation targets for Japan requires deep transformations in the energy system, in particular in the power generation sector. Decarbonization of this sector is unclear due to the uncertain nuclear policy after the 2011 Great East Japan Earthquake. However, many other uncertainties need to be considered, namely the...

This presentation outlines the analysis results of a questionnaire survey targeting the households in Hyogo prefecture, which received the ‘Uchi-eco Diagnosis’ (A tool to check the household energy use and recommend carbon mitigation countermeasures). It is indicated that solar PV and energy efficient water heaters have been largely applied in the...

本稿では日本の2050年までの温室効果ガス，エネルギーシステムのシナリオを，複数のエネルギーモデルもしくは統合評価モデルを用いて定量化し，それらを相互比較することによって，不確実性を踏まえた長期の気候政策の評価を行う。

This presentation outlines the activities being carried out under the UNEP 10FYP project on low carbon and resilient urban food systems.
