Resources for the Future iv Abstract Industrial energy consumption represents almost 40 percent of current global total final consumption and is still dominated by fossil fuels. In this paper, we present key decarbonization options—namely fuel switching and electrification, carbon efficiency, material efficiency, carbon capture and storage, and circular economy practices—and analyze their potential for decarbonization in six main energy-intensive industrial sectors: steel, cement, chemicals, light manufacturing, aluminum, and pulp and paper. We then develop a framework to distinguish among the different modelling approaches to industrial energy demand and emissions, with specific focus on the data challenges that constrain modelling and the difficulties of modelling innovation and technology diffusion. We present the most widely used models of industrial energy demand and emissions and classify them along three key dimensions: the analytical approach underlying each model, the methodology used to generate decarbonization pathways, and the granularity with which different industrial sectors be represented. By highlighting the strengths and weaknesses of available tools for industrial emission modelling, we point to necessary future model development efforts that would greatly improve the ability to develop deep decarbonization pathways for industry.

Introduction Increasing carbon efficiency and switching to carbon-neutral technologies for industrial production are imperative to achieve deep greenhouse gas (GHG) emissions reductions and to address climate change, as well as to ease concerns regarding energy security and higher energy prices. Energy consumption by the industrial sector represents almost 40 percent of current global total final consumption and is still dominated by fossil fuels, in particular coal. In 2021, industry was the second-largest emitting sector, after power generation, and was directly responsible for emitting 9.4 gigatonnes (Gt) of CO 2 . This estimate, which is equivalent to a quarter of global emissions, does not include indirect emissions from electricity used for industrial processes (IEA 2022c). Industrial energy and carbon intensities vary significantly across sectors as well as within sectors across different countries, with six sectors emerging as particularly energy- and emissions-intensive (see Section 2). The aim of this paper is to describe the most common approaches to the modeling of industrial emissions, with a particular focus on the ability of available models to depict the different mitigation options relevant for energy-intensive industries. These options range from increasing energy efficiency to developing and deploying novel negative-, zero-, or low-emissions technologies. Importantly, producing quantitative forecasts of industrial energy demand and emissions is strongly dependent on the availability of past data for model calibration. Furthermore, different modeling approaches and methods are characterized by the capacity to provide more or less detailed scenarios in terms of geographic, sectoral, and technological detail. Understanding the strengths and weaknesses of available approaches and tools for industrial energy and emissions modeling provides the basis for developing and interpreting results that can be used to inform energy- and climate-related policymaking. We also describe the most promising deep decarbonization options in each sector and discuss whether and how these options are represented in industrial energy models. It is important to recognize that deep emissions reductions cannot be achieved by pursuing a single decarbonization strategy alone; rather, these reductions are more likely to be achieved through a combination of many mitigation options, as well as investment in and support for different technologies and subtechnologies. Conversely, ignoring some of these options and promoting only select ones reduces the likelihood of achieving deep decarbonization targets. Therefore, our assessment of the relevance of various mitigation options for industrial deep decarbonization should not be interpreted as suggesting that one option should be chosen over the others. Resources for the Future 2 The paper is organized as follows. Section 2 identifies and describes the energy-intensive sectors that account for the majority of industrial energy demand and emissions, the focus of this paper. Section 3 reviews the available strategies through which industrial energy emissions can be reduced. Section 4 illustrates more detailed and specific technological options in each of the key energy-intensive sectors. Section 5 provides an overview of the data available to measure industrial energy demand and emissions, which are critical inputs for model development and calibration. It also discusses the difficulty of obtaining data to model several of the decarbonization approaches that are relevan
