The IPCC’s Fifth Assessment Report estimates lower costs of climate change and higher costs of abatement than the Stern Review. However, current UN negotiations focus on stabilising atmospheric concentrations of greenhouse gases at even lower levels than recommended by Stern. This column argues that, given realistic estimates of the rate at which people discount the future, the UN’s target is probably too stringent. Moreover, since real-world climate policy is far from the ideal of a uniform carbon price, the costs of emission reduction are likely to be much higher than the IPCC’s estimates.

In recent years, European coal consumption has increased, while natural gas consumption has declined – despite Europe’s commitment to reduce greenhouse-gas emissions. This perverse scenario is partly attributable to EU policies. Subsidies to renewables and energy efficiency targets have the unfortunate side effect of lowering carbon prices, thus partially offsetting their environmental benefits. Raising the EU carbon price would be preferable to employing multiple policy instruments, since it would minimise distortions in energy markets, achieve cost efficiency, and raise fiscal revenues.

Matthew Kahn of the University of California, Los Angeles, talks to Romesh Vaitilingam about global warming – and the incentives for individuals, cities and nations to reduce their greenhouse gas emissions or to adapt their lives to a warmer planet. He explains how free market capitalism might drive effective climate change mitigation or adaptation. The interview was recorded at Growth Week in London in September 2011.

Many policy proposals to limit greenhouse-gas emissions revolve around efforts to tax carbon emissions. But many studies point out that such energy taxes are regressive. This column models the distributional impacts of carbon pricing on over 15,000 US households, challenging the view that the policy by itself is regressive.

At the Global Economic Symposium in Schleswig-Holstein in September 2008, Nebojsa Nakicenovic of the Vienna Institute of Technology and the International Institute for Applied Systems Analysis spoke at a session on energy versus climate change. Afterwards, he talked to Romesh Vaitilingam about the options for reducing greenhouse gas emissions – improved energy efficiency; renewables; nuclear energy; and carbon capture and storage.

US climate change policy relies on corporations voluntarily reducing their greenhouse gas output. But recent research shows that pledging to cut carbon is bad for business, which is why so few firms take such voluntary measures. Reducing carbon emissions will require regulation.

If the world wants to stabilise atmospheric greenhouse gases at 550 parts per million, massive changes are required, especially in the energy sector. This article discusses means and costs of drastically reducing carbon emissions.

A new climate change prediction market has been launched. Here are the details on motivation and participation.

Targets and trading must be at the heart of a global agreement to reduce greenhouse gas emissions, according to Sir Nicholas Stern delivering the Royal Economic Society’s 2007 annual public lecture today, ahead of next week’s world summit on climate change in Bali.
