Novel, advanced sensors, dynamic development of information technologies as well as modern high-performance computers applied in different fields of human activity result in large amount of data. Consequently, these data, grouped in the data sets are both large and complex. The complexity come from the several mutually excluding factors like acquisition with different sensors at various times, ...

Mining is among the oldest industries. It is the primary source of raw materials for most of the sectors. Little is known about the complex inter-sectoral carbon linkages of the mining industry. In this work, we estimate the inter- and intra-sectoral carbon linkage impacts of the mining sector across ten major economies by applying an input-output model, and the hypothetical extraction method a...

Xinjiang’s industrial sector accounted for more than 80% of the total energy-related carbon emissions. A further understanding of each industrial sub-sector’s carbon intensity is very necessary to make differentiated policies and measures. This paper applied index decomposition analysis and attribution analysis to examine the influencing factors and each sub-sector’s contributions to the change...
