| Abstract |
Without disruptive change, greenhouse gas (GHG) emissions from fossil production of chemicals and plastics will double by 2050. The transition to net-zero GHG emissions requires a concerted strategy for the whole chemical industry due to its integrated supply chains. A cost analysis is needed to determine the required investments and to design carbon-pricing incentives. Here, we present cost-optimal investment pathways for the global production of chemicals and plastics by using a bottom-up process model that captures the complexity of the chemical industry. To accomplish net-zero, capital expenditures need to increase by 36-51 % over the next 30 years. In contrast, the total annualized cost could be similar ( + 4 %) to fossil-based production. Net-zero production and its costs will rely on the availability of renewable electricity and biomass. At the same time, high recycling rates are a key to keeping resource demands low and reducing the sensitivity to high resource prices.(c) 2022 The Authors. Published by Elsevier Ltd.
