Freshwater Policy

In Global Environment Outlook - GEO-6: Healthy Planet, Healthy People

Various policy approaches show that water quantity and quality have serious implications for human and ecosystem health, and that these interactions are driven by changes in multiple sectors. Governance is increasingly opened up to non-State actors, such as the private sector and civil society. Decision-making thus needs to consider the full range...

Sustainability Pathways (SSP1) Fundamentals for cities

11th Integrated Assessment Modeling Consortium (IAMC) annual meeting

Shared socioeconomic pathways (SSPs) have been developed by global climate change communities for analyzing long-term global societal transitions through science-driven analysis. SSPs can be transformed into local-scale socioeconomic pathways; however, the urban scale requires an in-depth understanding of specific local significant factors. Three...

Evaluation of long-term urban transitions in a megacity’s building sector

In Sustainable Cities and Society

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...

Energy system transformations for the long term mitigation target in Japan

3rd Japanese- German Workshop on Renewable Energies

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...

Evaluation of Japan’s long term climate mitigation goal under uncertain nuclear power with the AIM/CGE model

24th AIM International Workshop

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.
