Singapore is the most industrialized and urbanized country in Southeast Asia and is totally dependent on oil and natural gas imports to satisfy its energy needs. Its national energy policy framework seeks to find a balance between maintaining Singapore's competitiveness, improving energy...

In the European Union (EU) and in Germany the transport sector is the only sector with increasing CO2 emissions (in the EU by about 32 % and in Germany by about 1 % since 1990). Especially in road freight and air transport a further strong increase is forecasted. In the transport sector this...

This study explores the link between environmental degradation, economic growth and income inequality within the framework of the environmental Kuznets curve (EKC) literature. To investigate this issue, we examine how inequality affects carbon dioxide (CO2) emissions and their relationship with...

We model the choice of transportation mode in a simplified Hotelling-like city, with a fixed number of total travellers, fixed road capacity and with no trade-off between when to travel and the time spent in a queue. A person that chooses to take her own car will inflict a congestion cost on all...

Long run developments such as income growth and urban sprawl lead one to expect a continuous decline of thecontribution of non-motorised transport modes to the performance of transport systems. In terms of the totalnumber of trips, non-motorised transport modes have retained high shares,...

This paper concerns optimal emissions of greenhouse gases when catastrophic consequences are possible. A numerical model is presented which takes into account both continuous climate-feedback damages as well as the possibility of a catastrophic outcome. The uncertainty in the model concerns...
