This paper studies the implications for climate policy of the interactions between environmental and knowledge externalities. Using a numerical analysis performed with the hybrid integrated assessment model WITCH, extended to include mutual spillovers between the energy and the non-energy...

China had been singled out by Western politicians and media for dragging its feet on international climate negotiations at Copenhagen, the accusations previously always targeted on the U.S. To put such a criticism into perspective, this paper provides some reflections on China's stance and...

China's unilateral pledge to cut its carbon intensity by 40-45 percent by 2020 relative to its 2005 levels raises both the stringency issue, and given that China's pledge is in the form of carbon intensity, reliability issues concerning China's statistics on energy and GDP. Moreover, as long as...

In this paper we aim at theoretically grounding the Reducing Emissions from Deforestation and Forest Degradation (REDD ) scheme as a contractual relationship between countries in the light of the theory of incentives. Considering incomplete information about reference levels of deforestation as...

This paper updates the existing meta-analysis in coral reef recreation taking into account the previous work of Brander et al. (2007) but considering some stated preference biases and/or effects. The present meta-analysis uses twice the number of observations as the previous one and sheds more...

The importance of a focus on mobility and the kilometres travelled using light duty vehicles is reflected in the persistence of strong demand for personal mobility and emissions that tend to be linked with population and economic growth. Simulation results using the WITCH model show that changes...

The Stern/Nordhaus controversy has polarized the widely disparate beliefs about what to do in order to tackle the climate challenge. To explain differences in results and policy recommendations, comments following the publication of the Stern Review have mainly focused on the role played by the...

Two decades have passed since the Clean Air Act Amendments of 1990 launched a grand experiment in market-based environmental policy: the SO2 cap-and-trade system. That system performed well but created four striking ironies. First, by creating this system to reduce SO2 emissions to curb acid...
