Low birth rates, restrictive immigration policies, and decades of economic stagnation are marking Japan’s transition to a post-growth society. All levels of government have hurried to address the new challenges ahead. In this desperate run for survival, the development of new high-speed railway lines in peripheral areas has been met with high...

Scenario analyses have been used in multiple science-policy assessments to better understand complex plausible futures. Scenario archetype approaches are based on the fact that many future scenarios have similar underlying storylines, assumptions, and trends in drivers of change, which allows for grouping of scenarios into typologies, or archetypes...

Climate change has been one of the central issues for long-term transformations of cities. However, environmental loads have not been effectively taken into account for future urban plans. Specifically, possible reductions of carbon emissions from cities significantly rely on technological progress and human lifestyle changes, among other factors...

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.

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...

The achievement of long-term targets for climate mitigation in Japan faces several uncertainties with respect to the availability of power generation technologies. Starting with the difficult situation of nuclear power deployment after the 2011 events, the effect of technological constraints on the reduction of large amounts of greenhouse gases...

The feasibility of the commitment for climate mitigation encapsulated in the NDC of Japan may be hindered by the uncertain situation of nuclear power supply. We developed scenarios to assess Japan’s NDC under different nuclear power supply paths. A computable general equilibrium (CGE) model is applied to evaluate the impact on the energy mix, and...

A tool was developed to serve a two-fold purpose: gathering of scenario data from integrated assessment models (IAMs) into a consistent dataset, and straightforward visualization of key data from multiple models. The approach adopted in the development of the tool can be potentially applied to any IAM MIP that follows the IAMC data submission...
