This paper investigates a pollutant abatement investment under ambiguity in a twoperiod setting. We consider there are representative consumer and firm in an economy and formulate the social welfare maximization problem. Then we numerically derive the optimal level of abatement investment. Furthermore, we analyze the comparative static effects of the model’s parameters and find an increase in t...

Municipal solid waste landfills represent the dominant option for waste disposal in many parts of the world. While some countries have greatly reduced their reliance on landfills, there remain thousands of landfills that require aftercare. The development of cost-effective strategies for landfill aftercare is in society's interest to protect human health and the environment and to prevent the e...

Because New Zealand is a signatory to the Kyoto Protocol Framework Convention on Climate Change (1997), it is required to report national greenhouse gas emissions and maintain them at 1990 levels by 2008-2012. New Zealand has one of the highest per capita levels of the greenhouse gas methane [Woodward et al., 2001] and most of this arises from gut fermentation from ruminants. Not only does this...

First steps toward a broad climate agreement, such as the Kyoto Protocol, have focused on less than global geographic coverage. We consider instead a policy that is less comprehensive in term of greenhouse gases (GHGs), including only the non-CO 2 GHGs, but is geographically comprehensive. Abating non-CO 2 GHGs may be seen as less of a threat to economic development and therefore it may be poss...

This report examines different alternatives for replacing, treating, and recycling greenhouse gases. It is concluded that treatment (abatement) is the only viable short-term option. Three options for abatement that were tested for use in semiconductor facilities are reviewed, and their performance and costs compared. This study shows that effective abatement options are available to the photovo...

Strategies are sought to reduce economic and environmental costs associated with ruminant methane emissions. The effect of oral nitroethane or 2-nitropropanol administration on ruminal methane-producing activity and volatile fatty acid production was evaluated in mature ewes. Daily administration of 24 and 72 mg nitroethane/kg body weight reduced (P<0.05) methane-producing activity by as much a...

The very large reserves of methane, which often are found in remote regions, could serve as a feedstock for the production of chemicals and as a source of energy well into the 21st century. Although methane currently is being used in such important applications as the heating of homes and the generation of hydrogen for ammonia synthesis, its potential for the production of ethylene or liquid hy...

Non-cooperative game theoretical models of self-enforcing international environmental agreements (IEAs) that employ the cartel stability concept of d’Aspremont et al. (1983) frequently assume that countries are identical, and they can sign a single agreement only. We modify the assumption by considering two self-enforcing IEAs and also two types of asymmetric countries. Extending a model of Bar...

This research investigates the impact of both horizontal and vertical competition, on one hand, strategy types (commitment-based versus contingent-based equilibrium strategies), other pollution accumulated by two supply chains over time. We consider a two-stage game model where manufacturers retailers are involved in wholesale price contract, order to demand finite time horizon. In first stage ...
