Erratum: A novel global urban typology framework for sustainable mobility futures (Environmental Research Letters (2019) 14 (095006) DOI: 10.1088/1748-9326/ab22c7)

Abstract

In the first paragraph of the Introduction (page 1), the emissions due to transportation as (IEA 2017) were incorrectly reported. The corrected sentence is: Transportation remains a key driver for carbon dioxide emissions, accounting for nearly a quarter of the 32.3 GtC02-e emissions from fuel combustion globally in 2015 (IEA 2017). In the same paragraph, estimates from the International Transport Forum report (ITF 2017) were incorrectly reported. The corrected sentence is: The number of motorized urban passenger-kilometers is expected to nearly double to 48.4 trillion in 2050, while the number of motor vehicles on the road is estimated to grow to 2.4 billion within the same period, from the 2015 level of 1 billion (ITF 2017). Furthermore, in describing the MassTransit Moderate typology in the last row of table 6 (page 11), 'low congestion' should be 'moderate congestion.' Finally, in the last sentence of section 3.2.4 (page 11), there was a typographical error. The corrected sentence is: The Hybrid Moderate typology is largely represented in South America (e.g. Havana, Cordoba, Panama City) and Central Asia, while the Hybrid Giant cities are chiefly found in Eastern Europe and East Asia (e.g. Daegu, Hiroshima, Sofia). We stress that these typographical and reporting errors were limited to the paper, and have no bearing on the modeling framework presented in the manuscript.
