Mapping and modelling global mobility infrastructure stocks, material flows and their embodied greenhouse gas emissions - Data

Dynamics of societal material stocks such as buildings and infrastructures and their spatial patterns drive surging resource use and emissions. Building up and maintaining stocks requires large amounts of resources; currently stock-building materials amount to almost 60% of all materials used by humanity. Buildings, infrastructures and machinery shape social practices of production and consumption, thereby creating path dependencies for future resource use. They constitute the physical basis of the spatial organization of most socio-economic activities, for example as mobility networks, urbanization and settlement patterns and various other infrastructures. 
The data in this repository show the material stocks contained in global mobility infrastructure networks at the country-level and mapped at 5arcmins, as well as country-level estimates of material flows for maintenance, replacement and expansion of those infrastructures, and the associated GHG emissions from materials production. This repository contains all data as shown in figures of the article, including the GeoTIFF files for figure 3, and the supplementary data file containing full country-level results.
DataThis dataset includes the following data:

Global maps of material stocks in mobility infrastructure networks at 5 arcmins, separate for all roads, all rail-based infrastructure, as well as in total and per capita
Global country-level material stock estimates for mobility infrastructures
Global country-level estimates of material flows and associated GHG emissions for materials production
Material intensity in mass per area of road (kg/m²) per road type
Material intensity in mass per area of railway track (kg/m²) per railway type
Material intensity in mass per area (kg/m²) per bridges and tunnels
Material intensity factors are available for iron and steel, concrete, asphalt, aggregate (sand & gravel), timber, and other.
