This study first evaluates the pledges under the Copenhagen Accord using the DNE21+ model. Our estimates for the 2020 pledges fall collectively within the range of 46,700–49,100Mt CO2-eq. Our study also finds the efforts arising from the current 2020 pledges have wide-ranging implications in...

This paper evaluates the role of land in long-run climate stabilization mitigation scenarios. The details of land modeling for common stabilization policy scenarios are, for the first time, presented, contrasted, and assessed. While we find significant differences in approaches across modeling...

In order to limit global mean temperature increase, long-term greenhouse gas emissions need to be reduced. This paper discusses the implications of greenhouse gas emission reductions for major Asian regions (China, India, Indonesia, South-East Asia, Japan and Korea) based on results from the...

We investigate the efficiency and effectiveness consequences of emissions trading taxation. A theoretical partial equilibrium model is developed, showing that permits taxation distorts the equilibrium price and abatement efforts. Potentially counterintuitive conclusions concerning the tax...

R&D industry is introduced into a CGE model (KEI-Linkages) as a means to mimic the endogenous technological progress in the Korean economy. We found that providing across-the-board subsidy on R&D expenditure may lead to an increase in the carbon intensity, as well as the real GDP for the Korean...

Economic thought on climate policy as an instance of environmental regulation is strongly influenced by the principle of a uniform carbon price. Economists acknowledge that this principle breaks down in a “second-best” world with other distortions, such as taxes and market power in domestic...

This paper examines the cost structure of certified emission reductions (CERs) through various types of projects under the Clean Development Mechanism (CDM) of the Kyoto Protocol. Using the CDM project data, the costs of CERs and their variation across technology and over time and space are...

This paper argues that the 2009 pledge of $100 billion in 2020 by rich countries for mitigation and adaptation should not be used for mitigation by commercial firms in developing countries, since that would artificially create competitive advantage for such firms and provoke protectionist...

In this paper we discuss the scope of the adaptation challenge facing world agriculture in the coming decades. Due to rising temperatures throughout the tropics, pressures for adaptation will be greatest in some of the poorest parts of the world where the adaptive capacity is least abundant. We...

This paper provides a model assessment of the role of developing Asia in the context of climate change policies. We diagnose the potential response of Asian economies to the imposition of various climate policies, showing that if we were to equally price carbon across the world roughly half of...
