In contrast, this paper finds a positive relationship between per capita CO2 emissions from … transport and population density using a dataset of over 200 cities from 28 countries. This positive relationship holds when a … the estimated relationship between urban population density and emissions from transport is different across the two …

Transportation accounts for a substantial share of CO2 emissions, and decarbonizing transport will be necessary to … limit global warming to below 2°C. Due to persistent reliance on fossil fuels, it is posited that transport is more … difficult to decarbonize than other sectors. We test this hypothesis by comparing long-term transport energy demand and emission …
