The development of robust mechanisms for supply chain performance measurement have been identified as an integral step needed for the transition towards sustainable supply chain systems and a greener global economy. However, measuring the environmental performance of supply chains is a challenging task, due to several factors, such as the lack of standardised methodologies and the inherent multi-criteria nature of the problem. By leveraging the capability of a Multi-Regional Input-Output framework to handle the complex and global nature of supply chains, the current work presents a robust environmental sustainable performance measurement model underpinned by industrial lifecycle thinking. As a result, some theoretical insights are provided and an empirical application of the model to the Metal Products industry of the BRICS (Brazil, Russia, India, China, and South Africa) nations undertaken in an attempt to address some of the methodological and applied measurement challenges. In particular, this allowed the modelling of carbon emissions trends within, and between the BRICS nations and with the Rest-of-the-World over a 20-year period (1992-2011) as well as providing an opportunity to hypothesis on their future carbon emissions performances. Specific analyses of the Metal Product industry showed that demand represents the main driver for the increasing carbon footprint. However, the overall decline in reported carbon footprint was due to improvements in emissions intensity and efficiency gains induced by technology. The study further assesses the effects of imports and economic growth on carbon footprint and discusses the implications of the study to sustainability transition processes in the BRICS nations.
This paper adopts an industrial-level perspective towards understanding supply chains at the global level. An environmental sustainability performance model based on an industrial lifecycle thinking approach for analysing the carbon footprint of industrial-level supply chains is presented. Using this analytical perspective, a Multi-Regional Input-Output (MRIO) framework was developed and demonstrated in application to the BRICS nations and for the metal Products industries. In the assessment process, the total carbon footprint and the industrial-level supply chain efficiency expressed as a measure of the carbon emissions intensity was presented for each BRICS country between 1992 and 2011. Across the 25 industrial sectors that constitute the industrial supply chain of each country, it was determined, that over the 20-year period, for India, China and South Africa, there was a very strong linear correlation between the total cumulative carbon footprint and time. It was therefore hypothesised that the carbon footprint of these nations will continue to increase over time given the evidence of the last 20 years by following the same trajectory under a business as usual scenario.
