TL;DR: The most comprehensive and most highly resolved economic input–output framework of the world economy together with a detailed database of global material flows are used to calculate the full material requirements of all countries covering a period of two decades and demonstrate that countries’ use of nondomestic resources is about threefold larger than the physical quantity of traded goods.

TL;DR: In this article, the authors provide an in-depth review of the most recent multi-region input-output models used for the purpose of consumption-based environmental accounting and conclude that further research is mainly needed in two areas, improving data availability and quality and improving the accuracy of MRIO modelling.

TL;DR: This work reviews current footprints and relates those to maximum sustainable levels, highlighting the need for future work on combining footprints, assessing trade-offs between them, improving computational techniques, estimating maximum sustainable footprint levels, and benchmarking efficiency of resource use.

TL;DR: In this article, the authors provide a definition of the Footprint Family as a suite of indicators to track human pressure on the planet and under different angles, based on the premise that no single indicator per se is able to comprehensively monitor human impact on the environment, but indicators rather need to be used and interpreted jointly.
