The purpose of this paper is to describe global urban greenhouse gas emissions by region and sector, examine the distribution of emissions through the urban-to-rural gradient, and identify covariates of emission levels for our baseline year, 2000. We use multiple existing spatial databases to...

This paper investigates the pressure placed by cities on their environment with respect to urban air pollution. The analysis employs a spatially explicit global dataset of emissions to estimate urban emissions of four pollutants from a sample of 8038 cities world-wide in 2005. A cross-sectional...

Many states have adopted financial incentives to encourage market deployment of solar energy technology. This paper employs a cross-sectional time-series approach to evaluate the extent to which state solar financial incentives systematically encouraged market deployment of solar photovoltaic...
