Policies on climate change that encourage 'clean innovation' while displacing 'dirty innovation' could have a positive impact on short-term economic growth while avoiding the potentially disastrous reduction in GDP that could result from climate change over the longer term.

This report presents new evidence relating to the effects of climate policy in Europe, particularly the European Union Emissions Trading Scheme (EU ETS). The evidence is based on new data from almost 800 phone interviews we conducted with managers in manufacturing plants in six European...

There is an increasing demand for putting a shadow price on the environment to guide public policy and incentivise private behaviour. In practice, setting that price can be extremely difficult as uncertainties abound. There is often uncertainty not just about individual parameters but about the...

This paper considers how environmental policies should respond to macroeconomic downturns. It first explores the implications of the global economic downturn of 2008-09 for environmental policies, focusing in particular on the example of action against climate change. The arguments for and...

This article uses the European Patent Office Worldwide Patent Statistical Database to examine the geographic distribution and global diffusion of inventions in thirteen climate-mitigation technologies since 1978. The data suggest that until 1990 innovation was driven mostly by energy prices....

As many countries, regions, cities, and states implement emissions trading policies to limit CO2 emissions, they turn to the European Union's experience with its emissions trading scheme since 2005. As a prominent example of a regional carbon pricing policy, it has attracted significant...

There is an increasing demand for putting a shadow price on the environment to guide public policy and incentivize private behaviour. In practice, setting that price can be extremely difficult as uncertainties abound. There is often uncertainty not just about individual parameters but about the...

When regulated firms are offered compensation to prevent them from relocating, efficiency requires that payments be distributed across firms so as to equalize marginal relocation probabilities, weighted by the damage caused by relocation. We formalize this fundamental economic logic and apply it...

Carbon markets are central to the global effort to reduce greenhouse gas emissions. This paper introduces a new carbon market model that aims to simulate the development of the global carbon market over the next 10-20 years. The model is based on detailed regional and sectoral marginal abatement...

How much should governments subsidize the development of new clean technologies? We use patent citation data to investigate the relative intensity of knowledge spillovers in clean and dirty technologies in two technological fields: energy production and transportation. We introduce a new...
