Opportunities exist in G20 countries to strengthen existing climate policies. It can be shown from analyses at the national level that the emission reductions consistent with global pathways to reach the overall targets of the Paris Climate Agreement can be implemented. This is the main conclusion of a set of 11 national fact sheets developed as...

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...

Integrated assessment models (IAM) provide key information to allow policymakers to understand the possible outcomes of alternative development and climate policy scenarios. However, the complexity and large size of information resulting from IAMs, prevents straightforward communication of key insights to policy makers, unless a “translation...

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.

These country sheets present research findings on national long-term, low-emission pathways along the three Talanoa Dialogue questions: where are we, where do we want to go and how do we get there? The results highlight opportunities for enhancing ambition and success stories, and address country-specific topics. For Brazil: sustainable...

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 submission highlights the key findings of the discussion at the Japan-India Climate Policy Research Workshop, held in July 2018 in India. The key messages include: 1.Enhancing multiple co-benefits aids further acceleration of the efforts in reducing the GHGs and other climate relevant emissions to achieve the long-term goal of the Paris...
