This report summarises the main ideas, proposals, scientific achievements, consensus and conflicting issues that emerged at the Second EFIEA Policy Workshop, held at Fondazione Eni Enrico Mattei, Palazzo delle Stelline, Corso Magenta 63, Milan, Italy, March 4th-6th, 1999. EFIEA, the European...

The paper proves the existence and uniqueness of a noncooperative steady state in the context of a model of climate change. It also explores the possibility of cooperation and attainment of an optimal steady state. It is shown that the problem is similar to that in the static model (Chander and...

This paper applies the theory of social situations to international environmental agreements on greenhouse gas emission reduction. The usual pessimism on the size of stable coalitions among world regions is challenged for two alternative cases, namely by introducing farsightedness and by...

The purpose of the present paper is to describe the role of uncertainty and technical change in an environmental context. Which impact does ecological uncertainty have on physical and R&D investments' decisions? How are pollution trajectories modified when uncertainty is taken into account? To...

In this paper we introduce the CLIMNEG World Simulation (CWS) model for simulating cooperative game theoretic aspects of global climate negotiations. The model is derived from the seminal RICE model by Nordhaus and Yang (1996). We first state the necessary conditions that determine optimal...

Enhanced energy efficiency occupies a central role in evaluating the efficacy and cost of climate change policies. Ultimately, total greenhouse gas (GHG) emissions are the product of population, economic activity per capita, energy use per unit of economic activity, and the carbon intensity of...

As the Copenhagen Accord indicates, most of the international community agrees that global mean temperature should not be allowed to rise more than two degrees Celsius above preindustrial levels to avoid unacceptable damages from climate change. The scientific evidence distilled in the Fourth...

Global governance institutions for climate change, such as those established by the United Nations Framework Convention on Climate Change and the Kyoto Protocol, have so far failed to make a significant impact on greenhouse gas emissions. Following the lead of Elinor Ostrom, this paper offers an...
