The COP27 (United Nations Climate Change Conference) in November 2022 once again highlighted the fact that countries are starting from different positions when it comes to emissions and climate policy. This Weekly Report classifies countries into representative profiles based on their past,...

Meeting net-zero emissions targets requires major and ongoing reductions in the use of fossil fuels. We focus on the role of three key emitters in a large dimensional, 30 country/region energy and trade model, designated as GTAP-R, to meet minimal Paris Agreement targets, illustrating the path...

There is a multi-dimensional need for studying the energy situation in Turkey and to obtain insight into the development of CO2 emissions. On the one hand, recent projections of the OECD show that Turkey has a yearly GDP growth potential of over 7%. On the other hand, recent projections of UNDP...

Unless developing Asia decarbonizes its development, global warming is unlikely to stay below the internationally agreed limit of 2°C above preindustrial levels. Integrated assessment modeling offers insights into how a low carbon transition can be achieved. The Sixth Assessment Report of the...

Pricing carbon is a central concern in environmental economics, due to the importance of emissions trading schemes worldwide to regulate pollution. This paper documents the presence of small and large jumps in the stochastic process of the CO2 futures price. The large jumps have a discrete...

Energy subsidies are causing adverse effects on the economy and environment stimulating inefficient resource allocation and excessive energy consumption. Therefore, multiple positive effects are likely to be obtained if subsidies are reduced or removed completely. This study estimates indirect...

This study explores the reduction potential of greenhouse gases for major pollution emitting countries of the world using nonparametric productivity measurement methods and directional distance functions. In contrast to the existing literature we apply optimization methods to endogenously...

The international carbon market, specifically the Clean Development Mechanism (CDM) created by the Kyoto Protocol, is an important contributor to the breathtaking growth of renewable energy in China. Ever since its debut, it has been at the center of the policy debate whether the CDM achieves...

Abstract The reduction of greenhouse gases is the key action to limit global warming. An important source of greenhouse gas emissions and pollution is the inefficiency of production processes. We report results from a stochastic nonparametric efficiency analysis using directional distance...

This study explores the reduction potential of greenhouse gases for major pollution emitting countries of the world using nonparametric productivity measurement methods and directional distance functions. In contrast to the existing literature we apply optimization methods to endogenously...
