Since the Kyoto Protocol, black carbon and other non-gaseous short lived climate pollutants (SLCPs) have played little role in global climate policy making. Over the past ten years, however, there has been an increasing recognition in the climate science literature of their importance for the...

Congress is likely to consider domestic climate change legislation during 2009, with a cap-and-trade system continuing to draw support from the Obama Administration and many leaders in Congress. Yet cap-and-trade regulations would take years for EPA to develop and implement, the desired price...

The United States has long suffered from a schizophrenia about energy policy. The importance of one of the factors in energy policy, the environment, has never been formally defined. Climate change adds another distinct layer to this complexity, as neither energy policies nor environmental...

This Article challenges the prevailing view that state action on climate change is misconceived because it cannot meaningfully impact greenhouse gas emissions. We argue that inducing technological change provides an independent ground for state programs; one can think globally and still act...

"Prices versus quantities" (Weitzman 1974), a hugely influential paper, is widely cited (and taught) in current debates about the best policy to reduce greenhouse gas emissions. The paper's criterion for ranking policies suggests that technological uncertainty favors taxes over cap and trade....

We provide ex-post empirical analysis of the effects of climate policies on carbon dioxide emissions at the aggregate national level. Our results are based on a comprehensive database of 121 countries. As climate policies we examine carbon taxes and emissions trading systems (ETS), as well as...

This paper provides ex-post empirical evidence on the effects of green technology support policies, in comparison with other climate policies, on carbon dioxide emissions at the aggregate national level. The paper uses cross-country dynamic panel estimation for a sample of 38 countries over the...

The social cost of carbon (SCC), commonly referred to as the carbon price, is the monetized damage from emitting one unit of CO2 to the atmosphere. The SCC is typically obtained from large-scale computational Integrated Assessment Models (IAMs) that consolidate interdisciplinary climate research...

We examine the impact of a carbon tax on consumer choices via a large-scale online randomized controlled trial. Higher taxes generally reduce the demand for high-carbon goods. Compared to an import tax, a carbon tax reduces demand when the tax is zero (i.e., announced but not levied) but leads...

The article discusses the ongoing green transition towards climate neutrality in 2050 with a focus on the options of green growth, zero- or de-growth. First, the key facts about the greenhouse effect and the status quo are shown with special attention to the industrialisation of emerging...
