Denmark has been a frontrunner in policies that reduce greenhouse gas emissions and now plans to cut emissions by 70% by 2030 from 1990 levels and to achieve carbon neutrality by 2050. Such ambition induces halving emissions from 2019 levels and making the same emission abatement effort in ten...

Reducing air pollution is a major policy challenge, especially in densely populated urban areas where human exposure to emissions is considerable. This paper develops and examines a series of scenarios for the evolution of transport-related emissions in the area of Santiago, Chile. The analysis...

Switzerland has low greenhouse gas emissions per capita as compared to other countries, which reflects the strong reliance on energy sources emitting few greenhouse gas emissions, especially in electricity generation, and little heavy industry. Greenhouse gas emissions have remained almost the...

Urbanisation in China has long been held back by various restrictions on land and internal migration but has taken off since the 1990s, as these impediments started to be gradually relaxed. People have moved in large numbers to richer cities, where productivity is higher and has increased...

European governments are increasingly committed to road safety, due to the impact of road accidents in terms of economic loss and as a public health threat. In addition to regulation, providing better road infrastructure is an essential strategy to promote road safety. This paper investigates...

This paper reviews the recent experience of Germany in encouraging innovation to reduce negative environmental impacts of economic activity. The essence of the German approach to policy-induced environmental innovation is discussed in the context of changing policy objectives, and illustrated...

This paper discusses the contribution that kerosene taxes could make to decarbonising international air travel post COVID-19. Reaching climate neutrality by mid-century requires that all sectors, including aviation, cut emissions strongly. The paper argues that clarity on decarbonisation...

This paper presents the results of an ex post evaluation of the impacts of a vehicle tax reform in Ireland, by carrying out a full social cost benefit analysis of a vehicle tax reform that began in Ireland in 2008 and shows that whilst successful in improving the fuel economy of new passenger...

This paper discusses the main external costs related to road transport and the design of taxes to manage them. It provides an overview of evolving tax practice in the European Union and the United States and identifies opportunities for better alignment of transport taxes with external costs....

At political boundaries, local leaders often have weak incentives to reduce polluting activity because the social costs are borne by downstream neighbors. This paper exploits a natural experiment set in China in which the central government changed the local political promotion criteria and...
