There is a relationship between urban air pollution and economic activity: economic activity generates pollution, for instance through transportation; in turn, pollution spreads around and generates economic disutility. To account for this feedback effect, we propose a spatial model of city...

We present a meta-regression analysis of the relation between the concentration of carbon dioxide in the atmosphere and changes in global temperature. The relation is captured by "climate sensitivity", which measures the response to a doubling of carbon dioxide concentrations compared to...

We couple a spatially homogeneous energy balance climate model with an economic growth model which incorporates two potential policies against climate change: mitigation, which is the traditional policy, and geoengineering. We analyze the optimal policy mix of geoengineering and mitigation in...

Climate Engineering, and in particular Solar Radiation Management (SRM) has become a widely discussed climate policy option to study in recent years. However, its potentially strategic nature and unforeseen side effects provide major policy and scientific challenges. We study the role of the SRM...

We study a dynamic game of climate policy design in terms of emissions and solar radiation management (SRM) involving two heterogeneous regions or countries. Countries emit greenhouse gasses (GHGs), and can block incoming radiation by unilateral SRM activities, thus reducing global temperature....

Using data on institutional investors' bond holdings, we investigate the resilience of green bonds to the COVID-19 shock in a difference-in-differences framework. We find that during the COVID outbreak green bonds experience lower sales, on average, while in normal times no significant...

This paper shows that, when the price of emission allowances is sufficiently high, emission trading schemes improve the emission efficiency of highly polluting firms. The efficiency gain comes from a relative decrease in emissions rather than a relative increase in operating revenue. Part of the...

The rationale of voluntary corporate initiatives is often explained with preparedness for future regulation. We test this hypothesis for the Chicago Climate Exchange (CCX) and the Climate Leaders (CL), two popular voluntary US environmental programs to curb carbon emission that were operating...

Carbon dioxide removal (CDR) is a potentially important climate strategy for attaining low climate stabilization objectives. However, climate analysis has indicated a possible weakening of the ocean carbon sinks -the largest in the world- in relation to CDR deployment. Here, we provide an...

Water is a multidimensional issue, involving water availability, access to freshwater, spatial and temporal distribution of resources, competition among its uses, ecosystems conservation, climate-related disasters and risks and several other aspects. The water security approach manages such...
