In order to formulate policies in response to climate change, it is essential to forecast future greenhouse gas (GHG) emissions over the long term. The Intergovernmental Panel on Climate Change (IPCC) developed the IS92 emission scenarios in 1992, which have contributed to climate change studies...

We have been developing a policy support tool, AIM/impact[policy], for use in the integrated assessment of global warming control targets including the stabilization of greenhouse gas concentrations, economically efficient emissions paths to realizing these targets, and consequent impacts and...

The Food and Agriculture Organization of the United Nations (FAO) has estimated that in 2010–2012, 868 million people were undernourished worldwide. At the same time, FAO reported that approximately 1.3 billion tons of food were lost or wasted globally in 2007, which was equivalent to...

In order to respond to climate change, it is essential to describe possible future greenhouse gas (GHG) emission trajectories in both nonintervention and intervention terms. This paper analyzes long-term GHG mitigation emission scenarios according to alternative development paths in the world...

Japan’s long-term CO<Subscript>2</Subscript> emission reduction scenarios are assessed with a computable general equilibrium model with recursive dynamics, which was modified in order to assess the effects of renewable energy supply. The period of assessment is from 2000 to 2050 and the increase of gross domestic...</subscript>

Using a bottom-up model, the effectiveness of carbon tax policy and a policy mix related to a carbon tax in Japan are assessed to reduce CO<Subscript>2</Subscript> emissions to the targeted level in the first commitment period of the Kyoto Protocol. In this simulation, only existing technologies and practical new...</subscript>

This study assesses the impacts of introducing an oil products tax on the general economy, economic structure, energy consumption, and air pollutant emissions (CO<Subscript>2</Subscript>, SO<Subscript>2</Subscript>, and NO<Subscript>x</Subscript>) in China using a static computable general equilibrium (CGE) model. The conclusion is that taxation on oil products...</subscript></subscript></subscript>
