Nowadays, an important debate in the international economies is the problem of greenhouse gas emissions and climate change related. Discussions begin to gain the world with the signature of the Kyoto Protocol (1997), where an international agreement was reached to reduce global emissions....

In our paper, we test the stability of the unadjusted and adjusted Environmental Kuznets Curve (EKC). Our results provide evidence in favour of the significance of the adjusted EKC hypothesis in which the impact of per capita GDP on the intensity of CO2 emissions is evaluated conditionally to...

The environmental Kuznets curve (EKC) has been extensively criticized on econometric and theoretical grounds. Recent econometric results and case studies show that national emissions of important pollutants are monotonic in income but changes in technology can lead over time to reductions in...

Using a stacked differences-in-differences approach, we study the effects of Low Emission Zones (LEZs) in Germany. The implementation of stage 1 and 2 LEZs, which banned the most pollution-intensive vehicles from city centers, significantly reduced PM10 concentrations. The most restrictive third...

We study the importance of anticipated learning - about both environmental damages and abatement costs - in determining the level and the method of controlling greenhouse gas emissions. We also compare active learning, passive learning, and parameter uncertainty without learning. Current beliefs...

Energy system and power market models refrain from distinguishing between private and social discount rates. We devise a strategy to account for diverging private and social discount rates in intertemporal optimization frameworks, resulting in an optimal carbon tax above the marginal damage when...

In this paper we investigate the introduction of an export tax on steam coal levied by an individual country (Australia), or a group of major exporting countries. The policy motivation would be twofold: generating tax revenues against the background of improved terms-of-trade, while CO2...

In this work, we solve a real-world facility location problem by means of a mixed integer linear programming model. The problem is faced by an Italian multi-utility company operating in the sector of waste management. The company works in several Italian regions to collect and treat the urban...

There is a relationship between urban air pollution and economic activity: economic activity generates pollution, for instance through transportation; in turn, pollution spreads around and generates economic disutility. To account for this feedback effect, we propose a spatial model of city...

The paper studies the effectiveness of a refunded emission payments (REP) scheme in achieving a specific target path of NOx-emission reductions. A REP scheme levies a charge on emissions and refunds the collected funds back to the emitting firms. REP schemes have been highlighted as a remedy to...
