Previous studies have found an inverse (or negative) correlation between urban population density and per capita emissions from land transport. In contrast, this paper finds a positive relationship between per capita CO2 emissions from transport and population density using a dataset of over 200...

Existing studies have investigated the environmental dividends of substituting high-speed rail for other energy-intensive vehicles from an engineering standpoint, but they have yet to explore the economic effects of high-speed rail and the associated carbon emission reduction benefits. To fill...

To what extent have national fiscal policies contributed to the decarbonisation of newly sold passenger cars? We construct a simple model that generates predictions regarding the effect of fiscal policies on average CO2 emissions of new cars, and then test the model empirically. Our empirical...
