Make wind and solar power even cheaper by opening up access to the electricity gridand ending fossil-fuel subsidies, urge Gernot Wagner and colleagues. Putting a price on carbon dioxide and other greenhouse gases to curb emissions must be the centrepiece of any comprehensive climate-change policy. We know it works: pricing carbon creates broad incentives to cut emissions. Yet the current price of carbon remains much too low relative to the hidden environmental, health and societal costs of burning a tonne of coal or a barrel of oil.

All environmental policies involve costs of implementation and management that are distinct from pollution sources’ abatement costs. In practice, regulators and sources usually share these administrative costs. We examine theoretically an optimal policy consisting of an emissions tax and the distribution of administrative costs between the government and regulated sources of pollution. Our focus is on the optimal distribution of administrative costs between polluters and the government and the optimal level of the emissions tax in relation to marginal pollution damage.

Climate change is a serious threat to Africa, in general, and sub-Saharan Africa, in particular, as it is expected to have significant economic, social, and environmental impacts.

This paper analyzes how fossil fuel-producing countries can counteract climate policy. We analyze the exhaustion of oil resources and the subsequent transition to a backstop technology as a strategic game between the consumers and producers of oil, which we refer to simply as ‘OECD’ and ‘OPEC’, respectively.

Santiago was one of the first cities outside the OECD to implement a tradable permit program to control air pollution. This paper looks closely at the program’s performance over the past 10 years, stressing its similarities and discrepancies with trading programs in developed countries, and analyzing how it has reacted to regulatory adjustments and market shocks. Studying Santiago’s experience allows us to discuss the drawbacks and advantages of applying tradable permits in less developed countries.

We use household survey data and income-outcome coefficients to analyze fuel tax incidence in Costa Rica. We find that the effect of a 10 percent fuel price hike through direct spending on gasoline would be progressive, its effect through spending on diesel—both directly and via bus transportation—would be regressive (mainly because poorer households rely heavily on buses), and its effect through spending on goods other than fuel and bus transportation would be relatively small, albeit regressive.

Although fuel taxes are a practical means of curbing vehicular air pollution, congestion, and accidents in developing countries—all of which are typically major problems—they are often opposed on distributional grounds.

We explore the possibilities of using incentive-based environmental regulations of CO2 emissions from international civil aviation. In theory incentive-based instruments such as an emission charge or a tradable emission permit system are better regulations than so-called command-and-control regulations such as emission limits or technology standards.
