Abstract:
This discussion paper aims to further awareness of opportunities to address loss and damage caused by climate change-related slow onset events (SOEs) through social protection. The analysis is based on a review of interdisciplinary theoretical and empirical literature. The findings suggest that designing comprehensive, climate-responsive social protection strategies can strongly support proactive measures to avoid, minimise and address the complex, long-term impacts of SOEs on human health, livelihoods, poverty and inequality. This entails improving the effectiveness and extending the coverage of existing social protection systems; mainstreaming climate concerns, including risks associated with SOEs, into national social protection frameworks; integrating social protection with broader climate and development policies and strategies; and developing innovative and transformational approaches to social protection. To this end, several issues for research and policy are discussed. Overall, the paper attempts to set the groundwork for an advanced research and policy agenda on social protection and climate change as well as emphasise the need for wider consideration of social protection in global climate change debates. In addition, the study aims to inform the future work of the Executive Committee of the Warsaw International Mechanism for Loss and Damage associated with Climate Change Impacts in the working areas of SOEs and comprehensive risk management approaches.

72. With or Without You: How the G20 Could Advance Global Action towards Climate-Friendly Sustainable Development

Abstract:
With a collective responsibility for 80% of global greenhouse gas emissions, while representing 80% of global wealth, it is imperative that the countries of the G20 throw their weight behind the implementation of both the Paris Climate Agree-ment and the 2030 Agenda for Sustainable Develop¬ment. In the past, the G20 has demonstrated that it can do that. The G20 Summit in November 2015 in Antalya, Turkey, provided strong support for the climate agreement signed a month later at the UN Climate Change Conference (COP21) in Paris. In 2016 in Hangzhou, China, the G20 adopted an Action Plan on the 2030 Agenda for Sustainable Develop¬ment and committed to “further align its work” with the 2030 Agenda. Even though both agendas have emerged in the multilateral context of the United Nations system, the G20 is expected to exert strong political leadership to address global climate change and to achieve sustainable development. Yet, since 2017 the G20 has struggled to provide such leadership, as support for multilateral commitments, especially those involving ambitious climate actions, appears to be fading. Crucially, opposition to strong multilateral climate policy in the US and Brazil resorts to outright climate denialism at the highest levels of government. These developments are challenging the G20, and BRICS and the G7 for that matter, to sustain support for multilateral commitments on climate and sustainable development. The rise of populist and unilaterally minded parties in European club members may further the risk of side-lining climate and sustainability-related issues in the G20 process. This does not bode well at a time when the G20’s support could be a vital ingredient for the success of the United Nations’ summits on climate action and sustainable development, both scheduled to convene in New York in September 2019 – less than three months after the Osaka G20 Summit in Japan. Following our analysis, we identify four ways forward that should be conducive to harnessing the G20’s economic weight and political clout to push more ambitious global action towards climate-friendly sustainable development, in spite of apparent discrepancies between domestic agendas and global understandings.

Abstract:
This paper provides an overview of what is actually known about the relationship between climate change and human mobility in West, East and Southern Africa – the most affected regions of Sub-Saharan Africa. Although there is a general lack of data on “climate migration”, trends can be deduced from the growing number of case studies and research projects. This paper also formulates some recommendations for German and European development policies for addressing “climate migration” in Africa. The adverse effects of climate change in the three regions are mainly linked to increasing rainfall variability and a higher frequency or intensity of floods and droughts. These effects are a major challenge for human security. The consequences for human mobility, which range from forced displacement to circular labour migration, are embedded in a complex and very context-specific set of political, social, economic, cultural and ecological factors. Due to generally fragile contexts and armed conflicts, the risk of forced displacement in the context of climate change is probably the highest in the Horn of Africa. In all three regions, many households affected by climate change can be considered “trapped” – mobility is not an option for them at all. If mobility is possible, it often takes the form of individual and circular labour migration. Under favourable circumstance (e.g. in the absence of labour exploitation), money earned by migrants might help their households to compensate or at least mitigate the losses induced by climate change (“migration as adaptation”). The ideal political response towards human mobility in the context of climate change is to avoid forced displacement, to maximise positive mechanisms of migration and to minimise negative aspects like labour exploitation. This demands a multi-sectoral and multi-level policy approach.

Abstract:
2019 has been marked by widespread uprisings throughout Latin America. In the last few months, protests have erupted in Bolivia, Ecuador, and Colombia, while Argentina elected a new leader, Bolivia’s president resigned following growing tensions with his political opponents and the military, and Peru’s leader is facing a political crisis. Largely fuelled by anger over graft, economic disparity, and the rising cost of living, the resulting social unrest has led to uncertainty over the energy sector outlook. Continued political and social turbulence will likely contribute to stagnant oil and gas production growth in these countries. Conversely, Brazil and Guyana are on track to become the region’s largest oil producers. In Brazil, pre-salt reserves have been attracting foreign investment, although further market-friendly reforms will need to be made to sustain development. Guyana, for its part, is in line to become the region’s newest petrostate and will see explosive economic growth in the coming years. Despite its large reserves, Venezuela is excluded from this study because the country’s political and economic turmoil, coupled with US sanctions, make any increase in investment highly unlikely in the short term.

75. Interactions between a Federal Carbon Tax and Other Climate Policies

Abstract:
Putting a price on carbon is a critical part of a low-cost strategy for reducing greenhouse gas (GHG) emissions, and a national carbon tax is a rare example of a climate change policy that has found bipartisan support in the United States. In 2018, legislation establishing a carbon tax was proposed by Democrats, Republicans, and bipartisan groups of US congressmen. However, while passing a carbon tax would certainly prove a significant step toward slashing emissions, simply adding a carbon tax to current policies is unlikely to achieve an emissions target at the lowest cost. Designing a carbon tax that contributes to achieving greenhouse gas reduction targets effectively and efficiently will require an examination of whether other new policies are also needed and whether existing policies can or should be changed or eliminated. With more proposals expected in 2019, such an examination is critical to ensuring both sufficient emissions reductions and an efficient set of policies that keep costs in check for taxpayers. As part of a broader carbon tax research program at the School of International and Public Affairs Center on Global Energy Policy at Columbia University, we have developed a framework for considering the interactions between a federal carbon tax and other policies that influence greenhouse gas emissions. Toward the goal of helping to design better policies, we identify policies and programs that are “complementary” to a carbon tax or “redundant.” A policy is defined as complementary if it: enables more cost-effective reductions of carbon dioxide emissions than a carbon tax would achieve on its own; or reduces GHG emissions and achieves a separate policy objective more cost-effectively than a federal carbon tax would on its own. Conversely, a policy is defined as redundant with a federal carbon tax if it leads to additional costs to society without achieving additional emissions reduction. In developing this framework, we recognize that real-world policies often do not fall cleanly into either category and that neither specifying the framework nor making the categorizations is an exact science. It is often difficult to identify a policy’s objective or evaluate its cost-effectiveness. In addition, the extent to which a policy complements a carbon tax depends on the nature of the carbon tax. Most obviously, with a lower carbon tax rate, fewer emission reductions would be achieved, and additional policies may be needed to make up the difference between the outcome and a science-based emissions reduction target. The results of the work, highlighted in the following table, indicate a relatively large number of policies can complement a carbon tax, such as those that support innovation in low-carbon technologies, tackle behavioral barriers to more efficient energy use, or improve public infrastructure and address barriers to reducing emissions unrelated to the price-related barriers addressed by a carbon tax. Conversely, the paper identifies regulations that force entities that pay the carbon tax to take specific actions to reduce their emissions, such as Environmental Protection Agency regulations of stationary sources of carbon dioxide emissions under section 111 of the Clean Air Act, as redundant with the carbon tax. The paper does not recommend which policies should be eliminated, changed, or added but intends to provide policy makers with information that will help them make these decisions.

76. The Risk of Fiscal Collapse in Coal-Reliant Communities

Center on Global Energy Policy
Abstract:
If the United States undertakes actions to address the risks of climate change, the use of coal in the power sector will decline rapidly. This presents major risks to the 53,000 US workers employed by the industry and their communities. 26 US counties are classified as “coal-mining dependent,” meaning the coal industry is a major employer. In these areas, the industry is also an important contributor to local government finances through a complex system of property, severance, sales, and income taxes; royalties and lease bonuses for production on state and federal lands; and intergovernmental transfers. While climate-related risks to corporations have received scrutiny in recent years, local governments—including coal-reliant counties—have yet to grapple with the implications of climate policies for their financial conditions. Importantly, the risks from the financial decline of coal-reliant counties extend beyond their borders, as these counties also have significant outstanding debts to the US municipal bond market that they may struggle to repay. To be sure, national climate policy in the United States is uncertain. Experts have long recommended strong policy action to reduce emissions, and for years, policy makers have largely ignored their advice. Nevertheless, with growing support by the public and policy makers, meaningful climate policy in the United States may be on the horizon, and those dependent on coal should be looking ahead to manage their risks. This paper examines the implications of a carbon-constrained future on coal-dependent local governments in the United States. It considers the outlook for US coal production over the next decade under such conditions and explores the risk this will pose for county finances. The paper also considers the responsibilities of jurisdictions to disclose these risks, particularly when they issue bonds, and the actions leaders can take to mitigate the risks. In short, the paper finds the following: ● Coal production in the United States fell by one-third between 2007 and 2017. Projections of the US energy system show this decline continuing gradually under current policies. However, even a moderately stringent climate policy could create existential risks for the coal industry, with potential declines in production of around 75 percent in the 2020s. ● A careful look at three illustrative counties shows that coal-related revenue may fund a third or more of their budgets. The exposure is compounded because school districts and other special districts within the counties also receive coal-dependent revenue. The complex system of local revenue instruments and intergovernmental transfers plus a lack of sufficiently detailed budget data makes it difficult to parse out just how reliant jurisdictions are on the coal industry. ● Estimates of the direct linkages between the coal industry and county budgets will almost certainly understate the risks because lost economic activity and jobs will have ripple effects across the economy. Case studies show that the rapid decline of a dominant industry has led to downward spirals and eventual collapses of local governments’ fiscal conditions, including the inability to raise revenue, repay debt, and/ or provide basic public services. ● Coal-dependent communities have a variety of outstanding bonds, and the risk of collapse of the coal industry threatens their ability to repay them. Despite regulations requiring disclosures to reflect risks to the financial health of municipalities, our review of the outstanding bonds indicates that municipalities are at best uneven and at worst misleading (by omission) in their characterizations of climate-related risks. Ratings reports are not much better than official statements in describing the risks associated with the exposure of some local governments to the coal industry. ● Climate policies can be combined with investments in coal-dependent communities to support their financial health. A logical source of funding for such investments would be the revenues from a price on carbon dioxide emissions, a necessary element of any cost-effective strategy for addressing the risks of climate change. A small fraction of revenue from a federal carbon price in the United States could fund billions of dollars in annual investments in the economic development of coal-dependent communities and direct assistance to coal industry workers. ● In considering reforms, several questions emerge for stakeholders. These include whether regulators should develop additional requirements for the disclosure of risks from future climate policies; whether ratings agencies should increase attention to the risks to local governments of climate policies; and whether stakeholders in the municipal bond market, such as borrowers, insurers, and underwriters, are appropriately accounting for risks to the coal industry.

77. PG&E: Market and Policy Perspectives on the First Climate Change Bankruptcy

Working Paper

Abstract:
The Pacific Gas and Electric (PG&E) bankruptcy, which was caused by liabilities resulting from massive wildfires, has widely been called the first climate change bankruptcy. It will likely not be the last, as climate change exacerbates natural disasters, leading to more frequent and intense wildfires, storms, and flooding. Wildfires alone could become up to 900 percent more destructive in certain regions by midcentury, and utility assets will also be increasingly exposed to threats stemming from hurricanes, rising sea levels, and other climate-related events. These extreme weather events will increase costs to utility-sector stakeholders, including investor-owned utilities, state and local governments, ratepayers, and taxpayers. These risks could place financial stress on utility companies, drive up electricity rates, crowd out essential investment in renewable energy and grid upgrades, and disrupt service. In this paper, Columbia University’s Center on Global Energy Policy reviews and analyzes the PG&E bankruptcy, assesses how capital markets have reacted to the bankruptcy through the lens of valuations in the US utility sector, and discusses policy implications of California’s recent legislative response to wildfire risk. This paper examines market indicators to assess investor expectations of climate risk exposure and likely cost allocation. Neither debt nor equity markets suggest widespread concern about climate risk in the utility sector. In the absence of strong market signals to encourage climate risk mitigation, the authors find that policy frameworks are needed to ensure that companies make necessary preventative investments and to define how costs will be allocated among stakeholders. This paper also reviews a recently passed California bill aimed at achieving these objectives and the lessons and best practices it offers for other policy makers. In short, the paper finds the following: Market indicators suggest that the California wildfires and subsequent PG&E bankruptcy have not caused imminent concern about climate risks in the utility sector. Equity valuations for the sector remain strong, with a utility stock index trading at a higher-than-average premium to the market benchmark. In credit markets, regulated utilities in the United States have raised more than $50 billion of corporate debt in 2019 to date, and borrowing spreads are currently below historical averages. There are several reasons why markets may not reflect widespread climate risk to utilities, despite the scientific evidence around likely future damage. Investors may believe that cost increases from climate change will occur too far in the future to materially impact the present value of their investments. Even if investors believe that climate change risks are material to valuation, they may also believe that such risks will not be considered by other investors for some time. Investors may be viewing wildfires as a California-specific risk, though the regional skew of wildfires is likely to shift significantly in coming years. They may lack the information or modeling tools for assessing the likelihood and geographic dispersion of high-impact tail events, such as the wildfires that PG&E faced. Financial markets may also reflect the belief that the costs of climate change in the utility sector will fall predominantly on ratepayers, insurance companies, and/or taxpayers rather than investors, and therefore investors may not view themselves as materially exposed. California’s recent creation of a wildfire insurance fund with contributions from both ratepayers and companies provides important policy lessons for designing comprehensive frameworks to allocate climate damage costs. These include the strengthening of both regulatory and corporate climate resilience expertise, mandating preventative investment as a prerequisite for cost-recovery mechanisms, defining utility financial exposure for climate damage situations, and providing cash for utilities to provide essential services when facing large disasters. The policy also presents some potential pitfalls that may be instructive for other state policy makers. The legislation sets aside large reserves for future damage, a necessary measure, but one that will result in higher electric bills. The bill does not allow utilities to earn a return on safety-related spending, which broadly diminishes incentives for proactive climate mitigation investment. The potential insufficiency of the wildfire fund also creates uncertainty about future cost allocation. Finally, failing to reform the California legal framework that allows utilities to be held liable for damages they did not cause perpetuates risks for companies and ratepayers. If the first climate change bankruptcy is indicative of a new reality, it is not that utilities are going to go bankrupt overnight. Rather, climate disasters will increasingly add financial stress to utility-sector stakeholders, as costs accumulate from both acute events and damaging extreme weather impacts. Adapting the regulatory bargain for a climate-exposed future will require lawmakers, regulators, and shareholders to develop new approaches and new incentive structures to ensure an accountable, robust utility sector. Moreover, while climate change is already presenting real financial challenges to utilities, it will not be the only sector to face large climate-driven costs. Other corporate actors can look to the utility experience to better understand how policy makers, investors, and companies will respond to the growing financial threat from climate change.

78. Engaging State-Owned Enterprises in Climate Action

Author:
Philippe Benoit

Working Paper
Institution:
Center on Global Energy Policy
Abstract:
Policy makers, academics, and others have devoted significant effort over the past three decades to considering how best to incentivize households and private companies to reduce their greenhouse gas (GHG) emissions. There has been much less discussion about how best to incentivize state-owned enterprises (SOEs) -- companies that are either wholly or majority owned by a government -- to cut emissions. Yet when it comes to energy sector GHGs, these state companies are among the world’s leading emitters. They are major emitters at both the country and global levels, notably from electricity generation. In the aggregate, they emit over 6.2 gigatonnes of carbon dioxide equivalent per year in energy sector GHGs, which is more than every country except China. Public sector companies are also major providers of low-carbon alternatives, such as renewables and nuclear power, and importantly, they often operate under incentives that are quite different from those facing their private sector counterparts. Given the emissions profile of SOEs, the nature of their corporate mandates, and their ownership structure, Columbia University’s Center on Global Energy Policy undertook research to examine how best to engage these companies in efforts to lower greenhouse gas emissions as part of its ongoing work on climate change. The paper explores the role of these public sector companies in climate change, examines the effectiveness of market-oriented solutions such as carbon taxes in changing SOE behavior, and evaluates some other potential strategies for reducing their emissions. In short, the paper finds the following: The state-ownership structure of SOEs allows governments to exercise shareholder power to press for the implementation of their climate policy preferences. Providing public sector financing and making associated infrastructure improvements are other ways that a government can encourage its SOEs to invest in low-carbon alternatives. In contrast, many SOEs operate with nonfinancial mandates, market protections, and other conditions that limit their responsiveness to carbon pricing mechanisms that are effective in changing private sector behavior. There are other ways to alter public sector companies so that they embrace a greener pathway without being directed, especially if a firm’s management determines the pathway will serve its corporate interests. This can be especially important for state-owned companies that have the political weight to resist government climate policy pressures. In emerging economies with large SOE emissions and with governments willingly direct their SOEs, using these companies to reduce emissions is a policy tactic that can present implementation and other advantages because it requires the government to target a limited number of companies that the state already owns and controls. How much a government prioritizes climate change relative to other goals is the most critical factor that will determine the extent to which its SOEs prioritize low-carbon investments. Successfully merging climate goals into growth objectives, at both the broader economic and the SOE-company levels, increases the likelihood that a state company will engage in the low-carbon transition in a sustained manner.

79. 2019 Guide to Chinese Climate Policy

Working Paper

Center on Global Energy Policy
Abstract:
In 2018, China was the world’s leading emitter of heat-trapping gases by a wide margin. Its policies for limiting emissions will have a significant impact on the global climate for decades to come. From a historical perspective, China’s status as the world’s leading emitter is relatively recent. During most of the 19th and 20th centuries, Chinese emissions were modest. Then, in the early part of this century, as the Chinese economy boomed, Chinese emissions began to skyrocket, overtaking those from the United States around 2006. China’s cumulative emissions of carbon dioxide since the beginning of the Industrial Revolution are roughly half those from the United States. (Carbon dioxide, the leading heat-trapping gas, stays in the atmosphere for many years once emitted.) China’s leaders have declared that the impacts of climate change “pose a huge challenge to the survival and development of the human race” and that China is “one of the most vulnerable countries to the adverse impacts of climate change.”[11] The Chinese government has adopted short- and medium-term goals for limiting emissions of heat-trapping gases and a wide-ranging set of policies that contribute to meeting those goals. Those policies are shaped in part by other objectives, including promoting economic growth, cutting local air pollution and developing strategic industries. This Guide examines Chinese climate change policies. It starts with a review of Chinese emissions. It then explores the impacts of climate change in China and provides a short history of the country’s climate policies. The bulk of the Guide discusses China’s principal climate policies, explaining the policy tools the Chinese government uses to address climate change and related topics. Appendices provide background on institutions that shape climate policy in China. What are “climate policies”? Monetary and fiscal policies affect emissions and could therefore qualify, as could policies on many other topics. This Guide does not catalog all policies that could affect emissions or the climate, but instead focuses on policies most directly related to climate change, including those on energy, transportation, urbanization, forestry, climate adaptation and climate diplomacy. In choosing policies to focus on, I am guided in part by international convention and in part by governments’ extensive reporting on this topic. The Intended Nationally Determined Contributions submitted by more than 160 nations to the UN Framework Convention on Climate Change show a broad international consensus that policies on energy, transportation, urbanization and forestry, among others, are considered “climate policies.” The Chinese government’s official documents on climate change show the same.[12] Several official documents are important resources for anyone interested in China’s climate policies. Every year the National Development and Reform Commission (NDRC) publishes a report on China’s Policies and Actions for Addressing Climate Change.[13] These reports provide detailed information on a range of topics. Other key sources for understanding China’s climate policies include: China’s Intended Nationally Determined Contributions, submitted to the UN Framework Convention on Climate Change in June 2015;[14] Work Plan for Controlling Greenhouse Gas Emissions in the 13th Five-Year Plan, issued by the State Council in October 2016;[15] China’s First Biennial Update Report on Climate Change, submitted to the UN Framework Convention on Climate Change in December 2016;[16] China’s Second Biennial Update Report on Climate Change, submitted to the UN Framework Convention on Climate Change in December 2018;[17] and China’s Third National Communication on Climate Change, submitted to the UN Framework Convention on Climate Change in December 2018[18] Several themes run through these documents, including strong commitments to low-carbon development, cutting coal use, scaling up clean energy sources, promoting sustainable urbanization and participating actively in climate diplomacy. Implementation is fundamental to any policy. This is especially true in China, where policy implementation can be a considerable challenge. Key ministries may fail to coordinate. Resources for enforcement may be lacking. Policies designed to achieve different objectives may conflict. The priorities of provincial leaders may not align with policies from Beijing. For these reasons and more, stated policies—while important—are just part of the picture when it comes to understanding the Chinese response to climate change. The organization of this Guide reflects that. Most chapters start with a section of background facts. This background provides context and can help in forming judgments on the impacts of policies to date and potential impacts of policies in the years ahead. Where implementation has been especially challenging or successful, that is highlighted. This Guide can be read in parts or as a whole. Individual chapters are designed to stand alone and provide readers with information on discrete topics. The Guide as a whole is designed to provide an understanding of China’s response to climate change and the implications of that response for China and the world. The Guide can be accessed in three ways: by purchasing it as a book on Amazon.com by visiting the Guide to Chinese Climate Policy website at https://chineseclimatepolicy.energypolicy.columbia.edu/, and by downloading it for free from the website above or the website of Columbia University’s Center on Global Energy Policy—http://energypolicy.columbia.edu/ This is a “living document.” Many of the facts and policies it describes will change in the months and years ahead. As that happens, this Guide will be updated. New editions of the Guide will be released regularly.

80. Low-Carbon Heat Solutions for Heavy Industry: Sources, Options, and Costs Today

Author:
Julio Friedman
Publication Date:
10-2019
Content Type:
Working Paper
Institution:
Center on Global Energy Policy
Abstract:
Recent studies indicate there is an urgent need to dramatically reduce the greenhouse gas emissions from heavy industrial applications (including cement, steel, petrochemicals, glass and ceramics, and refining). Heavy industry produces roughly 22 percent of global CO₂ emissions. Of these, roughly 40 percent (about 10 percent of total emissions) is the direct consequence of combustion to produce high-quality heat, almost entirely from the combustion of fossil fuels. This is chiefly because these fuels are relatively cheap, are widely available in large volumes, and produce high-temperature heat in great amounts. Many industrial processes require very large amounts of thermal energy at very high temperatures (more than 300°C and often more than 800°C). For example, conventional steel blast furnaces operate at about 1,100°C, and conventional cement kilns operate at about 1,400°C. In addition, many commercial industrial facilities require continuous operation or operation on demand. The nature of industrial markets creates challenges to the decarbonization of industrial heat. In some cases (e.g., steel, petrochemicals), global commodity markets govern product trade and price. Individual national action on the decarbonization of heavy industry can lead to trade disadvantage, which can be made acute for foundational domestic industries (in some cases, with national security implications). This can also lead to offshoring of production and assets, leading to carbon “leakage” as well as local job and revenue loss (with political consequences). In many cases, lack of options could lead to dramatic price increases for essential products (e.g., cement for concrete, an essential building material). Risk of carbon leakage, price escalation, and trade complexity limits the range of policy applications available to address this decarbonization need. To explore the topic of industrial heat decarbonization, the authors undertook an initial review of all options to supply high temperature, high flux, and high volume heat for a subset of major industrial applications: cement manufacturing, primary iron and steel production, methanol and ammonia synthesis, and glassmaking. From the initial comprehensive set of potential heat supply options, the authors selected a subset of high relevance and common consideration: Biomass and biofuel combustion Hydrogen combustion (including hydrogen produced from natural gas with 89 percent carbon capture (blue hydrogen) and hydrogen produced from electrolysis of water using renewable power (green hydrogen) Electrical heating (including electrical resistance heating and radiative heating (e.g., microwaves) Nuclear heat production (including conventional and advanced systems) The application of post-combustion carbon capture, use, and storage (CCUS) to industrial heat supply and to the entire facility, as a basis for comparison The authors focus on substitutions and retrofits to existing facilities and on four primary concerns: cost, availability, viability of retrofit/substitution, and life-cycle footprint. In short, the paper finds: All approaches have substantial limitations or challenges to commercial deployment. Some processes (e.g., steelmaking) will likely have difficulty accepting options for substitution. All options would substantially increase the production cost and wholesale price of industrial products. For many options (e.g., biomass or electrification), the life-cycle carbon footprint or efficiency of heat deposition are highly uncertain and cannot be resolved simply. This complicates crafting sound policy and assessing technical options and viability. Most substitute supply options for low-carbon heat appear more technically challenging and expensive than retrofits for CCUS. Even given the uncertainties around costs and documented complexities in applying CO₂ capture to industrial systems, it may prove simpler and cheaper to capture and store CO₂. CCUS would have the added benefit of capturing emissions from by-product industrial chemistry, which can represent 20–50 percent of facility emissions and would not be captured through heat substitution alone. Critically, CCUS is actionable today, providing additional GHG mitigation to industrial heat and process emissions as other options mature and become economically viable. Hydrogen combustion provided the readiest source of heat of all the options assessed, was the simplest to apply (including retrofit), and was the most tractable life-cycle basis. Today, hydrogen produced from reforming natural gas and decarbonized with CCUS (blue hydrogen) has the best cost profile for most applications and the most mature supply chain, and it would commonly add 10–50 percent to wholesale production costs. It also could provide a pathway to increase substitution with hydrogen produced by electrolysis of water from carbon-free electricity (green hydrogen), which today would increase costs 200–800 percent but would drop as low-carbon power supplies grow and electrolyzer costs drop. Hydrogen-based industrial heat provides an actionable pathway to start industrial decarbonization at once, particularly in the petrochemical, refining, and glass sectors, while over time reducing cost and contribution of fossil sources. However, substitution of hydrogen will prove more difficult or infeasible for steel and cement, which might require more comprehensive redesign and investment. Most of the other options appear to add substantially to final production costs—commonly twice that of blue hydrogen substitution or CCUS—and are more difficult to implement. However, all options show the potential for substantial cost reductions. An innovation agenda remains a central important undertaking and likely would yield near-term benefits in cost reduction, ease of implementation, and a lower life-cycle carbon footprint. Prior lack of focus on industrial heat supplies as a topic leave open many possibilities for improvement, and dedicated research, development, and demonstration (RD&D) programs could make substantial near-term progress. To avoid commercial and technical failure, government innovation programs should work closely with industry leaders at all levels of investigation. New policies specific to heavy industry heat and decarbonization are required to stimulate market adoption. Policies must address concerns about leakage and global commodity trade effects as well as the environmental consequences. These policies could include sets of incentives (e.g., government procurement mandates, tax credits, feed-in tariffs) large enough to overcome the trade and cost concerns. Alternatively, policies like border adjustment tariffs would help protect against leakage or trade impacts. Because all options suffer from multiple challenges or deficiencies, innovation policy (including programs that both create additional options and improve existing options) is essential to deliver rapid progress in industrial heat decarbonization and requires new programs and funding. As a complement to innovation policy and governance, more work is needed to gather and share fundamental technical and economic data around industrial heat sources, efficiency, use, and footprint.
