“…In the European context, the inclusion of consumption of carbon intensive materials into the European Emission Trading System (EU ETS) has been explored in detail (Neuhoff et al, 2016) and is an option for consideration by the European Commission in its mandate to keep the Directive under review in light of international developments and the efforts undertaken to achieve the long-term objectives of the Paris Agreement. Effectively, products sold to European consumers are subject to a charge that is proportional to the weight of the materials covered by the consumption charge, multiplied by a benchmark for the carbon intensity of the production of the material through a conventional production process (Pauliuk, Neuhoff, Owen, & Wood, 2016). Such benchmarks have already been defined and quantified for the free allowance allocation and power price compensation under the existing EU ETS and other emission trading schemes globally (Zipperer, Sato, & Neuhoff, 2017).…”
